Integrating WMS and material tracking into SMT processes
A warehouse management system (WMS) organises stock and warehouse processes. In SMT manufacturing, material identity, jobs and confirmations must align with equipment and production systems.
When does it make sense?
When inventory information from storage, transport and production must be combined and traceable movements are important.
How the process works
Identification events capture material movements. Software associates them with inventory, locations and orders. The integration concept defines which systems own the data.
Configuration follows your application.
| Characteristic | Description |
|---|---|
| Data basis | Material ID, part, location and movement event |
| Integration | ERP, MES and equipment connectivity after interface review |
| Operation | User roles, booking rules and error handling |
Interfaces: distinguish each role
This overview describes the systems and standards to consider during planning. It does not mean every proposed device supports every interface.
| System or standard | What to define for the project |
|---|---|
| ERP | Part and inventory master data, ownership of bookings and stock reconciliation |
| MES | Production orders, material status and shop-floor feedback |
| IPC-CFX (IPC-2591) | Manufacturing-data exchange: check supported messages, version and endpoints |
| IPC-HERMES-9852 | Machine-to-machine communication in the SMT line: check the handover use case and implemented version |
IPC-CFX and IPC-HERMES have different roles. Interfaces available on the selected equipment must be verified. About IPC-CFX · About IPC-HERMES
Integration & prerequisites
Document the system of record, master data quality, identification and interfaces. Define inventory reconciliation, exception handling and recovery rules.
Limits & dependencies
Software integration is not a blanket compatibility promise. Available APIs, data fields and booking workflows must be assessed for the existing systems.
Practical questions
Which software modules are needed?
Depending on the process, warehouse management, material management, equipment control and robot coordination are combined. Required modules, interfaces and licences are defined against your existing IT.
Is existing SMT equipment automatically compatible?
No. Connectivity must be checked for the model, software version and available interface. We need the specific equipment configuration and interface documentation for the assessment.
Which system owns inventory: ERP or WMS?
Ownership must be defined clearly in your integration concept. We recommend assigning master data, physical stock, reservations and corrections separately. Also specify transfer direction and behaviour when transactions are delayed or fail.
Explore this solutionWhich interfaces and data formats are required?
The general product page does not replace an interface specification. Document available protocols, data fields, access rights, events and error codes before planning. Specific API, ERP or machine connections are confirmed against that documentation.
Explore this solutionWhat should an integration test cover?
We recommend testing a complete material journey: receipt, storage, reservation, retrieval, line handover and return. Add duplicate messages, connection interruptions and stock corrections. Reconciliation of physical material and system state should be part of acceptance.
Explore this solutionHow can duplicate postings be prevented when messages are resent?
Agree a unique transaction identifier for messages that change inventory. Resending the same transaction must not change stock again. Also define acknowledgements, retries and the order of related events. An important test is a connection failure after a successful posting but before its acknowledgement: the retry must be handled without a second inventory change.
Explore this solutionWhat roles do IPC-CFX and Hermes play in SMT integration?
IPC-CFX supports manufacturing-data exchange between equipment and higher-level systems. Hermes focuses on board flow and associated data between machines. The standards complement each other but serve different purposes. For material-logistics integration, check the messages, versions and functions actually available. Supporting a standard does not replace an agreed mapping of package, order and inventory data.
Explore this solutionWhich data and workflows matter when recovering from an IT outage?
Recovery needs locations, inventory, open orders and unacknowledged movements as well as master data. Define which actions are permitted while disconnected and how they will later be reconciled. A backup alone does not demonstrate operational recovery. Agree a restore test that includes user roles, permissions and reconciliation against the material physically present.
