Dear All, Attached is the sample project for the Modbus communication between CP341, CP 340 and 1Si (Master) and the third party (slave) devices. Manual for slave devices used in program backup also integrated in the attachment. Main driver block is FB50 (Modbus standard block) andthis block should be called for each master module. Blocks associated with the FB50 is, FB 7 = Modbus_Rcv (Siemens standard block) FB 8 = Modbus_Send (Siemens Standard Block) DB1 = Send list DB (Modbus Queries list) DB3 = Modbus Misc DB4 = Modbus Data (Received Data’s) Advantages of using this block,
Use the Modbus block and achive communication tasks quickly and easily without any problem. Please revert back for any clarification. AttachmentMODBUS_V6.0.zip (4350 Downloads) |
