Our management want to offer customers to control our machinery using MODBUS protocol. Does Beijer have a special manual (e.g. which functions are supported)? Which simulators or test programms are recommended? I found some on simplymodbus.ca. Are they good?

The manuals for all controllers are found in the same place. Modbus is a standard protocol, therefore it does not matter what programs you use to test it. They should all play together because of this standardization.

Thank You Mark.
The task is to send the value of register D0 , of PLC (for example, FX3U) after an external master demand through ethernet. I added controller"MODBUS": MODICON, Modbus Slave RTU/TCP. Created a new tag. What values should I put in the Tag table in the column "MODBUS" and in the column "FX3U"?

In each controller column you should put the address you want to read to/ or write from. Then look in the iX help file and read up on using the Data Exchange feature of iX. You can use it to read data from one controller, and send it to another.
