Hi all! I wonder if it possible to realise system like this. Each Station PLC must exchange data with PLCs after and before (e.g., PLC8 must exchange 100bytes with PLC6 and 100bytes with PLC4) via TSEND_C, TRCV_C. Each Station HMI will communicate only with local PLC. Central Station PC must collect cca 800bytes of data from each PLC. 1. Is this OK? 2. Is it OK to use 2 switches in branch station (stations 4 and 7), since 3xFO switches X300 are not compatibile with X100/200 (regarding waveleght)? 3. What about communication time-out for commands SEND/RECEIVE? Should I expect any problems? 4. What about aquisition cycle on PC? What do you reccomend for it? 1second? 5.Is it possible to use unmanaged switches (X100 series) since I can not see any advantages of managed switches here? Thanks!
