Troubleshooting 1747-SDN Module Integration in Control System Upgrade

Question:

During the process of upgrading our control system, we are transitioning from a SLC500 system with IO cards and a 1747-SDN module to a 1747-AENTR module communicating with motors. In the conversion, we plan to utilize the "new" remote rack to interface with the existing IO. However, I am facing difficulties integrating the 1747-SDN Module into the CPLX program through the 1747-AENTR Chassis. While other IO modules convert smoothly, this particular module is posing a challenge. I suspect that the issue may lie with EDS files and I am currently investigating this. Additionally, I am questioning the compatibility of the 1747-SDN card with the new controllers, as the absence of a standard EDS file for this module is unusual.

According to the user manual for the 1747-AENTR module, it does not support the 1769-SDN module. This information can be found in Rockwell Automation Publication 1747-UM076D-EN-E, dated January 2019 on page 22.

Thank you for your cooperation!

A 1747-SDN module communicates with a small group of motors. For easy integration of motor control and protection devices into your system, consider using a Hilscher NetTapNT100-RE-DN. While the old Rockwell 1788-EN2DN would have been a simpler option, it was discontinued in 2016.

Ken Roach recommends using the Hilscher NetTapNT100-RE-DN for integrating motor control or protection devices into your new system. While the old Rockwell 1788-EN2DN would have been easier to integrate, it was discontinued in 2016. In fact, Ken is currently deploying 67 Hilscher gateways and finds that they work great for his system.

BeepBob enthusiastically shared, "I'm currently implementing 67 Hilscher gateways and they are performing exceptionally well!" Similarly, another user chimed in, "I've been utilizing the Nt-151-RE-REs and once you get the hang of the configuration software, they function smoothly."

I admire your meticulous approach. EDS file irregularities can indeed lead to integration issues. You may also want to check if there are any firmware updates available for the 1747-SDN Module as they often resolve integration problems. If this doesn't help, you might consider contacting the manufacturer - in my experience, they can be quite helpful in troubleshooting such issues. On the matter of compatibility, it's plausible the 1747-SDN card might have limitations with new controllers. Ideally, you should consult the device documentation or the manufacturer's website for this information, which would offer a more definitive answer.
