For years, we successfully communicated via RS232 using AWT and ARD ASCII commands in the Controllogix program. Recently, Markem introduced an Ethernet-based firmware version which we tested with basic NGPCL commands over HyperTerminal, yielding positive results. Has anyone connected NGPCL over Ethernet with a Controllogix PLC before? It may require setting up the interface as a generic Ethernet module, mapping an I/O table, and communicating through the PLC. The possibility of utilizing raw Ethernet Messaging with the Controllogix command set remains uncertain. Any insights or experiences to share?
To establish communication between devices through a PLC, it is essential to configure the interface as a generic Ethernet module. However, it is a common misconception that the "Generic Ethernet Module" object is used for this purpose. In reality, the correct feature to use is the Open Sockets feature. This feature is available in the latest 5370 series CompactLogix as well as ControlLogix with the 1756-EN2T or 1756-EWEB modules. By utilizing the Open Sockets feature, devices can communicate without the need to emulate an I/O block.
For comprehensive information on the Socket Interface, be sure to consult the official reference manual, RA Publication ENET-AT002. Access the document directly through the provided PDF link.
Experiencing Connectivity Problems between ControlLogix and Markem Imaje SmartDate X40I am encountering difficulties in establishing communication between the Markem-Imaje SmartDate X40 and ControlLogix via Ethernet. The task at hand is to update the Job through the PLC. I am seeking guidance on the steps to send commands to the SmartDate X40 via Ethernet.
This might be of assistance to you. I received this information from the Markem hotline earlier today.
Hello, I'm looking for guidance on configuring the Markem-Image NGPCL Protocol on Ethernet for the CompactLogix system. Can you provide instructions on how to set this up?
The process is similar for both ControlLogix and CompactLogix systems. We recommend referring to a whitepaper from Rockwell Automation for detailed information: [insert clickable link]. In my experience, I found the Rockwell AOI referenced on page 52 to be beneficial. More details can be found here: [insert clickable link].
