Getting an old PLC onto Allen Bradley DH+

AI Thread Summary
An old Allen Bradley PLC-5/40 is being integrated into an existing DH+ network for bidirectional data communication, despite its lack of native DH+ support. The 1770-KF2 DH+ and Serial interface module is considered for this purpose, but there are concerns about whether it can operate transparently on the network without exposing itself. The user seeks assurance that the integration will not require different configurations compared to existing nodes on the DH+. They have reviewed the Rockwell KF2 documentation but found no relevant information. This inquiry serves as a last resort for obtaining clarity on the integration process.

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!

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
