Hello, I need help with solving rather trivial problem, which is tormenting me. Problem: - no communication between WinCC flexible and S7-200 224. Proof: - I/O field showing ###### as a sign of no connection - button has a function on press to write a constant to QB0 -nothing - button has a function on press write to a bit QB0.0 - nothing - button has a function on press write to a bit in a tagQB0, QB0.0 - nothing - Tx/Rx LEDs on RS232/PPI cable not flashing(no transmission) My goal is: - to create SCADA(on PC) with WinCC flexible - control and data acquisition from S7-200 CPU224 Connection between PC and PLC: - RS232/PPI cable: 6ES7 901-3CB30-0XA0 - settings: 9.6kbaud, PPI/Freeport, Local/DCE, 11bit(everything zero exepct DIP No2, for selection of speed 9600kbps) PLC address: 2 PC address: 0(tried others, nothing) PLC speed set up to 9.6 in system block with Micro/WIN PLC is communicating normally with Micro/WIN and WinCC(trough OPC server) I've done everything as here: link and link I tried to: - change Access Point of the application (S7ONLINE,Micro/WIN,custom)- nothing - change baud rate(in PLC and WinCC flexible) - change both addresses(PLC and PC) - tried another RS232/PPI cable(same type) - tried another PLC(same type) - tried another PC Also read trough: link, link, link, link So, if you read trough last two links, same problem, but it looks like that this problem isn't solved yet and I must ask my self, if I'm totally incompetent or is this simply not working. Thanks for reading and helping. |
