Example 1
In this example the “group 1 proportional band” with modbus address 5 is read.
DB associated to the instrument is DB 3, created with UDT5 or 6, and it is specified at the first input parameter
“DBNr”.
The instrument MODBUS address to call is 1.
The word reading operation code is 3
The word address to be read is 5.
The INValue parameter for this operation is indifferent.
When the bit M1.0 associated to the “Done” flag goes to 1, in the word MW108, associated to the OUTValue output
parameter, there will be the active setpoint value.
The request must be reset only when the “Done” flag goes to 1.
If there were errors the bit M1.1 would go to 1 and in the word MW110 we would have the error code.
