## Short answer

SIGMA MES is built for production and assembly lines and paperless production, from SIGMA Chemnitz, a certified Infor LN partner in Germany. The partner also offers integration through Infor OS/ION and web services, so the LN link is a stated capability, though the specifics need confirming for your version.

## Product

SIGMA MES for Infor LN

## Vendor

SIGMA Chemnitz GmbH

## Category

MES

## Integration

**Method:** LN-specific integration

**Detail:** 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.

**Method:** Infor OS / ION and web services

**Detail:** 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.

## Data Flows

**From:** LN production orders

**To:** SIGMA MES

**Data:** Orders, operations, bills of material and quantities

**Trigger:** Order release

**From:** SIGMA MES

**To:** LN

**Data:** Confirmations of quantity, time and scrap

**Trigger:** Operation reported on the line

**From:** LN

**To:** SIGMA MES

**Data:** Work instructions and material information for paperless display

**Trigger:** Order start or change

## Setup

### Define the line process

**Detail:** Map assembly steps, stations and what must be recorded at each, so paperless instructions reflect real work.

### Choose the integration path

**Detail:** Decide between ION messaging and web service calls with the partner, based on your LN version and monitoring capability.

### Align master data

**Detail:** Check items, routings, work centres and BOMs in LN are accurate enough to drive instructions.

### Configure stations

**Detail:** Set up terminals, user rights and the confirmation rules for each station.

### Pilot one line

**Detail:** Run a single line, compare confirmations with LN daily and fix mapping gaps.

### Plan support and upgrades

**Detail:** Agree who retests the MES interface when LN or Infor OS is upgraded.

## Pitfalls

- 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.

## Ai Layer

### Confirmation reconciliation

**Description:** Compare MES confirmations to LN order status and flag mismatches or duplicates for a supervisor.

### Line performance questions

**Description:** Ask where scrap or rework is concentrated by station and product, reading MES and LN data together.

### Instruction review drafts

**Description:** Draft updates to work instructions after an engineering change, held for engineer approval before release.

## Alternatives

- 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.

## Faq

### Who provides SIGMA MES for Infor LN?

**Answer:** 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?

**Answer:** 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?

**Answer:** 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.
