SUMMARY

The discussion focuses on integrating an Allen Bradley PLC-5/40 into an existing DH+ network for bidirectional data communication. The PLC-5/40 lacks native DH+ support but can utilize serial communication through the 1770-KF2 DH+ & Serial interface module. The user seeks confirmation on whether the 1770-KF2 can operate transparently on the DH+ network without exposing itself, ensuring compatibility with a legacy system. The inquiry highlights the need for clarity in the configuration process to avoid disruptions in the existing network.

PREREQUISITES
  • Understanding of Allen Bradley PLC-5/40 architecture
  • Familiarity with DH+ networking protocols
  • Knowledge of the 1770-KF2 DH+ & Serial interface module
  • Experience with legacy system integration
NEXT STEPS
  • Research the configuration settings for the 1770-KF2 DH+ & Serial interface module
  • Explore Allen Bradley documentation on PLC-5/40 serial communication capabilities
  • Investigate troubleshooting techniques for DH+ network integration
  • Learn about legacy system communication protocols and their compatibility with modern interfaces
USEFUL FOR

Control engineers, automation specialists, and technicians involved in integrating legacy PLC systems into modern communication networks.

Hey all,

I am trying to get an old AB PLC-5/40 onto an existing DH+ for data communication (both ways). The PLC does not support DH+ natively like SLCs but it is capable of serial communication.

I know that the 1770-KF2 DH+ & Serial interface module are used to bringing a computer into the DH+ network with a RS-232 connection. However, I am not sure if the 1770-KF2 will be capable of acting as if it is completely transparent on the DH+ and only exposes the PLC and not itself. Since I will be sending these information into a legacy system (20 years old?? ), I wanted to make sure it would not have to be configured differently from other nodes that are already on the DH+.

I looked through the Rockwell KF2 documentation twice now and havn't been able to find anything remotely similar. So this is my last resort.


Thanks all!

Sorry, because of all the specific part number, and the jargon, we can't find anyone to answer your question.
