Hello all. I am trying to communicate with an external device which is ModbusTCP compatible with a S7-1200 PLC. The external device is a heater and I would like to set the setpoint temperature of the heater and periodically check the actual temperature. So I used the example program from Mr.Pegia. When I downloaded the PLC configuration and the PLC code to the PLC I see the following status on the MB_Server block: 7002 - Intermediate call. Connection is being established. This does not change. The command consists of 10 characters, so I sent the following to change the setpoint of the temperature in HEX: 007B, 004D, 0000, 0000, 0000, 0008, 0009, 0008 000D,000A Can anyone please give me some input on what to try next. Cheers. Aleix ------------------------------------------------------------------------------------------ |

Hello Evereyone I am having one masibus 85xx+ scanner. I want the plc (s7 1200 cpu1214c) to read temperature values. I have used MB Client instruction in programme but showing error 7006. The scanner communicates via modbus TCP/IP interface. I am enclosing a zip file containing pic of scanner settings and the v13 programme that i have made. Pls help, its urgent Thanks AttachmentMODBUS TCP TEST 1.zip (1080 Downloads) |
