Will there be an external electronic card to achieve effective communication between them or could it be built? |

Hello trebol; As you see in the proposed table above, an OP77A supports Profibus-DP. If your PLC rack contains a CP 541 you might be able to connect it to the operator panel. CP 541 Communications Processor - Industry Support Siemens The reason that the OP 77B can connect to the S5-103U's porgramming port, which supports AS511 communications, is that it has a RS-232 interface (IF1B) that you can use with a TTY-RS-232 cable (with an addes 25-pin to 9-pin adapter). See for example this video: PC/TTY:cable between computer RS232 port and siemens simatic S5 The OP 77A does not support RS-232 communications, so this solution cannot be used. Hope this helps, Daniel Chartier |
