can you compose a MODBUS telegram with a macro ?

5 posts in this topic

I am controlling a Danfoss FC051 with a OMRON CJM1 plc using a modbus master program .

the control is done with a OMRON NS5 screen that reads the parameter value .

to change a parameter I need to send a modbus telegram to the FC051 with a specific Node address .

Can this be done with a macro that is activated by changing the value in a input box ?

a example would be most appreciated

Hallo Jay .

I am using FTP/IP communication

FTP is File Transfer Protocol.

Do you mean EIP protocol?

What is DP Protocol?

Mistake 1 : I use IP number to communicate between the screen and the PLC .

using a adapted program MODBUS master : see File SV357.

Mistake 2 : forgot to remove the DataProtocol V1 what is a Devicenet protocol for Danfoss inverters .

I am using Modbus for the control off the FC051 Danfoss drive .( see file ssp you need MCT10 from Danfoss to read the file  )

In the prog you may find the text " Smart Logic" what is a small program that runs in the Danfoss Drive
