Hi Team, require help in getting AB SLC5/04 to talk to Citect 7.2 sp4. via USB 232 convertor using AB_DF1 Driver. RSlinx 2.58 is talking to the PLC and l can up/down load.
I have tried all sorts of config's l have read on Citect KB as well as searched on this site. None of the configs line up to what is available on Citect Boards/Ports/I/O devices or RSlinx as drivers, as the example info seems to be quite old. As well as trying changing the Duplex and PLC Channel 0.
I have just been rereading another article were Ken Roach (back in2004) was explaining some of the complexities of using the serial comms to do the connection.
Q1) Is one of the issues that we have to use half duplex DF1 because we are trying to talk to 2 devices (i.e. PLC and Citect) were as Full duplex is for talking to one device only (i.e. PLC) hence why we have the complexity of polling?
Q2) Would anyone have the correct settings to enable me to talk to Citect via USB-RS232 and RSlinx2.58?
I have also tried doing comm’s via a 1747-KE series C. module but was unable to get info back via HyperTerminal software, although it says it is connected and l believe l had done things as per an instruction.
Q3) Am I right in thinking you can talk to Citect via serial comms and a 1747-KE without using RSlinx, which would then enable you to talk to the PLC via RSlinx + DF1?
Thanks for any help, as trying to config this is making my glasses starting to melt from all the steam coming off my brain ( I think l will try cooling it down from the inside with a beer)
Thanks for any responses to get this working.
