Issue
Can the IC GEN OPC Server communicate with an OPC XML-DA server?
Product Line
Satchwell BAS & Sigma
Environment
- IC GEN OPC Server
- Third-party OPC Clients
- OPC DA and OPC XML-DA protocols
Cause
The IC GEN OPC Server is designed to support OPC DA (Data Access) only. It does not natively support OPC XML-DA, which is a different protocol standard used by some third-party OPC servers.
Resolution
To enable communication between the IC GEN OPC DA client and a third-party OPC XML-DA server, a protocol translation gateway is required.
Recommended Solution:
Use a third-party gateway from Advosol, which acts as a bridge between OPC DA and OPC XML-DA. This allows the IC GEN OPC DA client to access data from XML-DA servers.
- For more information and to obtain the gateway, refer to Advosol’s OPC XML-DA Gateway (external link).
Configuration Example:
In the IC GEN OPC gateway.txt configuration file, reference the third-party OPC XML-DA server using the following format:
Item0=4^IndigoVision^192.168.246.95^Fromlv.analysis.motionalarm1^0
Explanation of fields:
IndigoVision: Name of the third-party OPC XML-DA server192.168.246.95: IP address of the serverFromlv.analysis.motionalarm1: OPC item path0: Item index or priority (as required by IC GEN)
Additional Notes
- Ensure the third-party gateway is installed and configured correctly on a supported operating system.
- IC GEN OPC version 4.05 or later is recommended for compatibility.
