Good Morning fellow automatons,
I am attempting a simple time measurement of data aquistion by a PLC-5 from a secondary device (in this case a KF2). The network (just these two
devices) is DH+.
What I would like to do is "see" a data request go out and the data come back. I'm not interested in truly analzing the protocol. (although that
would be fun too).
What I did was place a 485 to 232 on the DH+ network and monitor via Frontline test. The data that I see I would expect to contain many token
passing loops. However I get many errors that are probably related to data size and or parity which makes the data total indecipherable.
I ASSUME that datahighway+ is talking at 57.6k with 8 bits of data, 1 stop using standard 5v, high = 1 (485)logic is this true?
Any help would be appreciated
