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 (4380 Downloads) |

HiAbdel-Qader, The present program is made only for the modules CP341, CP340 and 1SI modules. I did not worked on S7 1200 plc. So I am not sure weather the same program will work with S7 1200. Please give a try and let me know about the result.

HI,
All the displayed errors are related to the Modbus Slave. The information about the error can be seen in the slave device manual. Check the Attached document at the page numbers 65 & 66 for the information about the error codes. It says clearly either check the slave device or See the manual of salve device.
