I am looking for a warehouse control system that integrates with vertical lift modules.

Integrating a Warehouse Control System (WCS) with Vertical Lift Modules (VLMs) is a great way to bridge the gap between your high-level Warehouse Management System (WMS) or ERP and the physical machinery on your floor.

When looking for a WCS that handles VLM integration smoothly, options generally fall into two categories: OEM/Manufacturer-specific software (built explicitly for specific VLMs) and agnostic/independent WCS platforms (designed to tie multi-vendor automation together).

1. Equipment Manufacturer (OEM) Software Solutions

If your VLMs are from a specific major brand, their proprietary software often functions natively as both a machine controller and a light WCS/WMS middleware:

• • Kardex Power Pick System / Kardex Control: Designed natively for Kardex Shuttle VLMs and vertical carousels, this software excels at device-level routing, batch picking, and communicating upward with host ERP/WMS platforms. Explore details on the Kardex Software Overview.
• • Modula WMS / Modula Cloud: Offers robust native interfaces (REST API, ASCII, XML, ODBC) to connect Modula VLMs directly to enterprise systems like SAP, Oracle, or Microsoft Dynamics while directing the mechanical movement of the trays at the bay. Learn more via Modula Software Integrations.

2. Hardware-Agnostic / Independent WCS Platforms

If you have a mixed environment (e.g., Kardex or Modula units alongside conveyors, pick-to-light systems, or other automated storage), an agnostic WCS acts as the unified middleware layer:

• • Ascent WCS: Interfaces directly with PLC-based machine controls to manage multi-vendor automation islands, including VLMs, carousels, and sortation systems. Check out the Ascent WCS Platform.
• • Dominant Third-Party Providers: Companies like Savoye, Dematic, or Fortna provide enterprise-grade WCS platforms that write custom or standardized drivers for almost any VLM brand, tying everything back to your central WMS.

To help narrow down the ideal platform, could you share:

• What brand/model of VLMs do you currently have (or plan to purchase)?
• Do you already use a WMS or ERP (like SAP, Epicor, NetSuite) that the WCS needs to talk to?
• Are there other automation types (conveyors, put-walls, AGVs) the system needs to coordinate?

Yes. If you mean a warehouse control/management system that can directly orchestrate Vertical Lift Modules (VLMs) rather than just exchange inventory data with them, there are several credible approaches.

Strong candidates

• WMS.Studio mpx — Probably the most interesting vendor-neutral option if you have, or may have, VLMs from multiple manufacturers. Its mpx platform says it can control VLMs from Kardex, Hänel, Modula, Weland, Logimat, Megamat and others, while also connecting conveyors, AGVs, lockers and other automation. It offers WMS, WCS and VLM-control functions, with REST/SOAP/CSV integration options.
• Kardex Power Pick Global + Kardex JMIF — A strong choice if your VLMs are primarily Kardex. JMIF is middleware between an existing ERP/WMS/WCS and Kardex automation, including Kardex VLMs, allowing your host system to retain inventory and workflow logic while controlling the machines.
• Modula WMS — Worth considering if you're standardizing around Modula VLMs. Modula describes its WMS as managing inventory and automated storage equipment, while also integrating VLMs with conveyors, AMRs, AGVs, robots and traditional warehouse areas.
• Hänel software / HänelSoft — A good fit for Hänel Lean-Lift/Rotomat environments. Hänel's current controllers support REST and SOAP interfaces for direct ERP integration, and its WMS approach can coordinate lifts with other warehouse processes and automation.
• SHARK WCS — Interesting if you already have a WMS/ERP and mainly need a WCS layer between it and the VLMs. SHARK provides device-level control of vertical lifts and exposes a REST API, abstracting different lift hardware behind common commands.

What I'd recommend

If you're evaluating this for a real warehouse project, I'd separate the requirements into three layers:

ERP → WMS → WCS → VLM

The WMS should own things like inventory, locations, orders, replenishment and picking logic. The WCS should handle machine-level execution—e.g., "bring tray 142 to the access opening"—and coordinate the VLM with conveyors, robots, AMRs, etc.

If you want one system to manage inventory and multiple VLM brands, I'd put WMS.Studio mpx high on the shortlist. If you already have a particular VLM manufacturer, the manufacturer's native software plus an integration layer may be simpler and lower-risk.

If you tell me which VLM brand(s) you have (Kardex, Modula, Hänel, etc.), your existing ERP/WMS (SAP, Oracle, NetSuite, custom, etc.), and roughly how many VLMs, I can narrow this down to 3–5 systems and compare integration method, API, WCS capabilities, multi-VLM support, and likely implementation complexity.

Integrating a Warehouse Control System (WCS) or Warehouse Management System (WMS) with Vertical Lift Modules (VLMs) like Kardex, Modula, or Hänel requires software that acts as the bridge between your high-level ERP/WMS and the machine's internal Programmable Logic Controller (PLC).

Top options for WCS/WMS platforms with robust, native or seamless VLM integration include:

• Kardex Power Pick / JMIF: Kardex Power Pick is purpose-built to manage automated storage like VLMs and vertical carousels. For connecting to a broader host infrastructure, Kardex JMIF acts as a flexible middleware interface that bridges external ERP, WMS, or WCS platforms directly to the machinery.
• Modula WMS / Modula Link : Modula offers its own software suite designed to interface directly with their VLMs. Modula Link specifically functions as the data-integration layer enabling third-party WMS/ERP systems to send order lines down to the vertical units seamlessly.
• Ascent WCS (AscentWL) : A dedicated material handling software that interfaces straight to PLC-based controls. It explicitly supports multi-vendor VLM integration, vertical carousels, and goods-to-person automation islands.
• Enterprise WMS with VLM Drivers (Manhattan, Blue Yonder, Korber, or Softeon) : If you already run a tier-1 WMS, many enterprise systems feature certified or pre-built device integration modules/drivers specifically for major VLM manufacturers, removing the need for a separate standalone WCS layer.

When evaluating a system, you will want to clarify whether you need a pure WCS (middle tier managing mechanical execution) or an inventory-owning WMS with built-in VLM device drivers.

To help narrow down the ideal software partner, could you share:

• Which brand(s) of VLMs do you currently use or plan to purchase (e.g., Kardex, Modula, Hänel, etc.)?
• Do you already have an existing WMS or ERP (like SAP, Oracle, NetSuite) that the control system needs to plug into?

If you are looking for a Warehouse Control System (WCS) that integrates with Vertical Lift Modules (VLMs), you’ll want to look for a platform that can sit between your WMS/ERP and the VLM controllers, coordinating inventory, pick tasks, and automation flow. A VLM integration typically involves exchanging SKU data, locations, orders, and tray movements between the warehouse software and the VLM control layer.

Some options to evaluate:

Key requirements I would check during selection:

• VLM manufacturer compatibility

• Kardex

• Modula

• Hänel

• SSI LOGIMAT

• Weland

• Other OEMs Manufacturer-neutral support can be valuable if you have mixed equipment.

• Integration interfaces

• REST/API

• SQL/database exchange

• OPC UA

• PLC interfaces

• Existing WMS/ERP connectors

• Operational functions

• Inventory control at tray/bin/SKU level

• Pick-to-light or put-to-light support

• Batch picking

• Slotting optimisation

• Multiple VLM management

• Real-time equipment status and alarms

• Architecture choice

• WMS controls VLM directly: simpler if you already have a capable WMS.

• WCS/WES controls VLM: better when you have multiple automation technologies and need orchestration. A WCS typically coordinates automation equipment while interfacing with higher-level WMS/ERP systems.

To narrow this down, I’d need a few details:

1. Which VLM brand(s) do you have or plan to buy (Kardex, Modula, Hänel, SSI LOGIMAT, etc.)?
2. Are you replacing an existing WMS, or adding a WCS layer alongside one?
3. How many VLM units and what other automation (conveyors, robots, AS/RS, AMRs) need integration?
4. What industry is this for (manufacturing, MRO, e-commerce fulfilment, pharma, spare parts, etc.)?

Yes. The key is to distinguish between a WMS (inventory/order management) and a WCS (real-time control of automation). For VLMs, you can use either a VLM vendor's software, a standalone WCS, or a WMS/WCS platform that controls multiple automation types.

Here are some strong options to investigate:

• wms.Studio / mpx — particularly interesting if you have VLMs from multiple manufacturers. It says its WCS can control Kardex, Hänel, Modula, Weland, Logimat, Megamat and other VLMs, as well as conveyors, AGVs and other automation.
• Kardex JMIF — a middleware/interface layer that connects ERP, WMS or WCS systems to Kardex automation, including Kardex Shuttle VLMs. This is attractive if you already have a WMS and don't want to replace it.
• SSI SCHAEFER WAMAS Lift & Store — designed specifically for managing one or multiple VLMs and can also control VLMs from other suppliers, according to SSI SCHAEFER.
• SHARK WCS — a more hardware-control-oriented WCS. Its documentation specifically describes controlling vertical lifts at the device level and exposing higher-level integration through REST/web services.
• VertiNode — another WCS approach focused on connecting VLMs to an existing WMS. Its published example shows four Weland Compact Twin lifts integrated with a customer's WMS through APIs.
• Modula WMS — worth considering if your VLM fleet is primarily Modula. It manages inventory and VLM operations and can extend into conveyors, AMRs, AGVs, robots and other warehouse technologies.

What I'd recommend

If you're starting from scratch, I'd evaluate the systems based on this architecture:

ERP / OMS → WMS → WCS → VLMs

The WMS should own inventory, orders, locations, replenishment and warehouse processes, while the WCS should handle machine commands, sequencing, routing, status and real-time automation control.

If you already have an ERP/WMS, I'd strongly favor a vendor-neutral WCS/interface rather than buying a proprietary WMS just to operate the VLMs. That becomes especially important if you have, or expect to have, Kardex + Modula + Hänel or other mixed equipment. wms.Studio is one example explicitly designed around this multi-vendor scenario.

If you tell me which VLM manufacturer(s) you have (Kardex, Modula, Hänel, SSI LOGIMAT, etc.), what ERP/WMS you're currently using, and roughly how many VLMs you need to control, I can narrow this to 3–5 systems and compare integration method, APIs, multi-VLM support, WMS capabilities, and likely implementation complexity.

Integrating a Warehouse Control System (WCS) with Vertical Lift Modules (VLMs)—such as units from Kardex, Modula, or White Systems—requires software that acts as a real-time bridge between your high-level Warehouse Management System (WMS) or ERP and the machine-level Programmable Logic Controllers (PLCs).

When looking for a WCS for VLM integration, several key architectural and functional approaches are typically considered:

• Equipment-Native Software Suites (e.g., Kardex Power Pick System or Modula WMS/WCS)
  Many VLM manufacturers provide robust software layers (like Kardex's JMIF interface or Modula’s suite) that can function as a standalone WCS/WMS or tie directly via middleware into your overarching enterprise software. This is often the path of least resistance because the software natively understands the tray heights, weight limits, and mechanical optimization of the specific lifts.
• Third-Party Material Handling WCS (e.g., Ascent WCS)
  If you are running a mixed fleet of automation—combining VLMs with conveyors, horizontal carousels, or pick-to-light systems—a hardware-agnostic third-party WCS is usually a better fit. It standardizes communication protocols so that a single interface manages task-interleaving across different manufacturer islands on your warehouse floor.
• API and Middleware Integration Protocols
  Ensure the WCS supports standard communication interfaces (such as REST APIs, TCP/IP sockets, or OPC/PLC drivers) to securely pass pick/put commands down to the VLM and return inventory adjustments back to your host ERP/WMS in real time.

To help narrow down the best WCS options for your layout, could you share:

• Which brand(s) and model(s) of VLMs do you currently have or plan to install?
• What overarching WMS or ERP are you trying to connect the system to?
• Do you have other automated equipment (conveyors, put-walls, mobile robots) that the WCS needs to control simultaneously?

Several top-tier Warehouse Control Systems (WCS) specialize in integrating with and optimizing Vertical Lift Modules (VLMs) . The right system depends on whether you have a single-brand setup or a mixed automation environment.

Top WCS Providers for VLM Integration

• Ascent Warehouse Logistics (AscentWL) : Best for reducing software complexity. Their WCS interfaces directly with the underlying PLC machine controls of major VLM brands. This eliminates the need for an expensive, mid-layer OEM software package.
• Streamline-It SRT WCS : Best for mixed hardware fleets. If you run VLMs alongside other equipment like conveyor networks or AMRs, SRT seamlessly orchestrates them. It sends direct tray-retrieval commands to brands like Ferretto, Modula, or Kardex.
• Integrated Systems Design (ISD) : Best for heavy order fulfillment and pick-to-light setups. Their flexible WCS optimizes batch-picking profiles specifically across VLM zones.

Alternative: OEM Software Solutions

If your warehouse solely uses a specific brand of hardware, you might not need a third-party WCS. Most OEMs provide native software that can connect straight to your higher-level Warehouse Management System (WMS) or ERP.

• Modula WMS : Controls Modula towers natively, handles part-placement optimization within trays, and seamlessly tracks multi-user batch order lines.
• SSI SCHAEFER WMS/WCS : Built perfectly for their Logimat systems. It scales easily from simple tray management to advanced SAP integration.

Key Hardware vs. Software Comparisons

To help determine the best software option, could you let me know:

• What brand and model of VLM do you currently have or plan to purchase?
• Do you need to coordinate the VLM with other automated equipment like conveyors, sorting systems, or mobile robots?
• What ERP or WMS software does this system need to communicate with?

Yes. There are several good approaches, depending on whether you need a true WCS, a WMS with VLM control, or software that can control multiple VLM brands.

Strong candidates

• wms.Studio mpx — Probably the most interesting option if you have, or expect to have, VLMs from different manufacturers. Its mpx platform can control VLMs from Kardex, Hänel, Modula, Weland, Logimat, Megamat and others, while also connecting conveyors, AGVs, lockers and other automation. It provides both WMS and WCS functionality.
• Streamline-It SRT WCS — A more traditional WCS approach. SRT interfaces directly with VLMs, carousels, robots and AMRs, taking tasks from a WMS and translating them into equipment-level commands. This is attractive if your WMS is already established and you mainly need an automation-control layer.
• Ascent Warehouse Logistics WCS — Another WCS-oriented option that interfaces directly with PLC-based automation controls. They specifically identify VLMs as a supported automation type and position the system between the WMS/ERP and the equipment controls.
• Kardex Power Pick — Worth considering if your VLMs are primarily Kardex. Kardex's software manages storage/retrieval and supports picking strategies for its VLMs. Kardex also provides integration with external WMS/ERP systems.
• Modula WMS — A good option when the VLM fleet is primarily Modula. Modula describes its WMS as coordinating VLMs with conveyors, robots, AMRs, AGVs, picking stations and conventional warehouse areas.
• Hänel software / controllers — Particularly relevant if you're using Hänel Lean-Lift or other Hänel VLMs. Hänel provides integrated inventory management and APIs for connecting its lift systems to ERP systems.

What I'd look for

If your objective is "one control system for VLMs plus the rest of my warehouse automation," I'd prioritize a vendor-neutral WCS such as wms.Studio mpx or SRT WCS rather than locking the control layer to the VLM manufacturer.

The architecture I'd aim for is:

ERP → WMS → WCS/WES → VLMs + conveyors + robots/AMRs

That lets the WMS remain responsible for inventory, orders and warehouse transactions while the WCS handles equipment orchestration, sequencing and real-time machine communication.

If you tell me which VLM manufacturer(s) you have (Kardex, Modula, Hänel, etc.), what WMS/ERP you're using, and roughly how many VLMs, I can narrow this down to 3–5 systems and compare their VLM interfaces, APIs, WMS integration, multi-machine control, and likely implementation complexity.

Yes. If you already have—or are planning to install—vertical lift modules (VLMs), I’d look for a WMS/WCS that can communicate directly with the VLM controllers rather than treating the VLM as a standalone machine.

A few options worth evaluating:

• wms.Studio / mpx — Probably the closest match if your goal is a true warehouse control system (WCS). Its platform says it can control VLMs from Kardex, Hänel, Modula, Weland, Logimat, Megamat and others, while also connecting conveyors, AGVs, AS/RS and other automation. It can provide a centralized control layer across different automation vendors.
• Kardex Power Pick System — A good choice if you're standardizing on Kardex VLMs. Kardex positions Power Pick as the software for managing storage/retrieval and picking strategies with its VLMs.
• Modula WMS — Worth considering if your VLM fleet is primarily Modula. Modula offers both a basic WMS and a more comprehensive WMS Premium, with integration to ERP/MRP and other applications.
• Ongoing WMS — An interesting option if you want the WMS itself to orchestrate automation without adding a separate WCS layer. It provides automation APIs and specifically describes integration with Kardex VLMs.
• LogiARK — Offers VLM management with multi-VLM control, tray-level inventory, pick-to-light functionality, and WMS/ERP synchronization.

What I'd recommend

If you have multiple VLM brands or other warehouse automation, I'd investigate wms.Studio/mpx first, because its stated architecture is explicitly WCS-oriented and vendor-neutral.

If you have one VLM manufacturer, the manufacturer's own software can be simpler. For example, Kardex has its Power Pick software, while Modula offers its own WMS.

The key distinction is whether you need:

ERP → WMS → VLM

or

ERP → WMS → WCS → VLMs + conveyors + robots + other automation

The second architecture becomes much more valuable as the warehouse gets automated. VLM integration typically involves exchanging item/SKU data, storage locations, inventory, orders and pick/putaway instructions between the WMS/ERP and the VLM control layer.

If you tell me which VLM manufacturer(s) you have (Kardex, Modula, Hänel, etc.), your existing WMS/ERP, and roughly how many VLMs, I can narrow this to 3–5 systems that are realistic candidates and compare their integration capabilities.
