OPC 40082-3 describes the interface between injection moulding machines (IMM) and liquid silicone rubber (LSR) dosing systems for data exchange via OPC UA. The target of OPC 40082-3 is to provide a standardised interface for IMM and LSR dosing system from different manufacturers to ensure compatibility.

The following functionalities are covered:

• General information about the LSR dosing systems
• Status information
• Process data

Synchronisation of dosing between IMM and LSR dosing systems is not part of OPC 40082-3 and must be done by additional interfaces e.g. via hardwired signals.

Safety related signals like emergency stop are not included.
