Good day! Here is a link to the project, which will comply. I can not understand what was happening. Is not any work on RS485. The task here is what I put: A. S7-1200 module with the RS485. Two. Sensors 30 pcs. Gas - RS485 (MODBUS RTU) We must make sure that the controller queried periodically sensors and filmed testimony from them in memory to him. Next on the LAN (Ethernet), they should arrive on the PC (as I understand it is necessary to use a Web server controller?). Am now at the stage: there is no connection from RS485 (on the controller display Tx and Rx, there is only DIAG - green light). Can you please tell what's the problem?
