Summary:

Connecting CitectSCADA OPC I/O Device to Rockwell FactoryTalk OPC Gateway Server.

OPC Sniffer returns an error of 0xc0040008 and fails at the AddItems call.

 

Solution:

The FactoryTalk server does not support the OPC 'topic name' in the AccessPath (where as RSLinx does). Completely removing the definition for access path from the citect.ini and then instead specifying the variable tag address as [TopicName]tag.name will resolve this.

FactoryTalk server supports DA2 so UseOPC2 = 1 must also be set in the citect.ini.
