I am using Zelio PLC SR3B101BD with SR3MBU01BD Modbus card and i am trying to read %MW16-19 registers. I can read %MW20-48 registers but when i read %MW16-19 I get zeros.
What's the problem?
Hi, The IOs of Zelio Logic are starting on Mobdus Register MW20 (decimal).
These values are always mapped to modbus.
If you want to read values from MW16-19 you need to write values into these Variabels.
If you don´t connect a value to these outputs. The modbus Value should alltimes 0.
I hope this will help you.
