This ladder logic code on the PAC Machine Edition software for PAC System RX3i controller enables the controller to function as an OPC UA server. OPC UA clients can easily connect to the controller, enabling seamless integration for enhanced process control and monitoring of industrial processes.
Knowledge Prerequisites:
Install PAC Machine Edition software v9.0 or greater on your Windows machine
OPC UA Server is supported using the embedded Ethernet port with RX3i CPE305/CPE310 firmware version 8.20 or greater. So, the controller firmware version should be greater than 8.2. But in this case the OPC server can be started from the PAC Machine edition software using ladder logic. To start the server using online OPC commands of software there are different requirements mentioned below
The PAC Machine edition version 9.5 and greater have OPC online commands present in the software that supports OPC UA. These commands help the user to start the OPC server directly instead of using the ladder logic. Also, the suggested firmware version of controller is 10.10 or greater for effective working with PAC machine version 9.5 or greater
