How SIGMA MES for Infor LN connects to Infor LN
LN-specific integration
SIGMA positions the MES as specific to Infor LN. The cited page does not detail transactions, so request a list of the LN objects read and written, and the supported LN versions.
Infor OS / ION and web services
The partner states that it also offers integration over Infor OS/ION and web services. ION suits message-based exchange of orders and confirmations, while web services suit direct calls, and the choice affects error handling and monitoring.
What data moves
| From | To | Data | When |
|---|---|---|---|
| LN production orders | SIGMA MES | Orders, operations, bills of material and quantities | Order release |
| SIGMA MES | LN | Confirmations of quantity, time and scrap | Operation reported on the line |
| LN | SIGMA MES | Work instructions and material information for paperless display | Order start or change |
Setting it up
- 1Define the line processMap assembly steps, stations and what must be recorded at each, so paperless instructions reflect real work.
- 2Choose the integration pathDecide between ION messaging and web service calls with the partner, based on your LN version and monitoring capability.
- 3Align master dataCheck items, routings, work centres and BOMs in LN are accurate enough to drive instructions.
- 4Configure stationsSet up terminals, user rights and the confirmation rules for each station.
- 5Pilot one lineRun a single line, compare confirmations with LN daily and fix mapping gaps.
- 6Plan support and upgradesAgree who retests the MES interface when LN or Infor OS is upgraded.
What usually breaks
- !Incorrect BOMs or routings in LN producing wrong instructions at stations.
- !Confirmations posted twice after a network interruption and a retry.
- !ION message failures not monitored, leaving confirmations stuck on the MES side.
- !Engineering changes in LN not reaching running orders on the line.
- !Language and localisation of work instructions left until late in the project.
A private AI layer across both systems
Confirmation reconciliation
Compare MES confirmations to LN order status and flag mismatches or duplicates for a supervisor.
Line performance questions
Ask where scrap or rework is concentrated by station and product, reading MES and LN data together.
Instruction review drafts
Draft updates to work instructions after an engineering change, held for engineer approval before release.

When something else fits better
- A general MES with a broad LN connector may suit multi-site groups better than a regional partner product.
- LN's own shop floor modules may cover simple reporting without a dedicated MES.
- For paper-based lines, digital work instructions alone may be a smaller first step.
Frequently asked questions
Who provides SIGMA MES for Infor LN?
It comes from SIGMA Chemnitz GmbH, which describes itself as a certified Infor LN partner in Germany. The product is aimed at production and assembly lines and paperless production, and the partner also offers Infor OS/ION and web-services integration.
Should I use ION or web services for the connection?
ION suits asynchronous, message-based exchange with queues you can monitor, while web services suit direct request and response calls. The right choice depends on your LN version, network layout and who will monitor failures, so decide it with the partner.
Can AI be used on-prem alongside the MES?
Yes. A private assistant on your servers can read MES and LN data read-only, reconcile confirmations and answer line questions without sending production data out. Any change to orders or instructions needs human approval.
