Modbus Reg Write
-
Hi Modbus experts. I have a energy meter and would like to set a certain register. Mango allows me to write to the register from the write tool see here write ok
When i add the point and try to set it i get this error in the logging console error.txt
Any Ideas?? -
There are a couple setting that might help. Are you able to read this register as well? If not you might need to set the data point to be a write only rather than read and write.
The other thing is on the data source setting try setting the Max Write Register count to 1. With modbus you can do a single write command or multiple write command. Mango will try and be as efficient as possible and some devices don't support the full modbus specification.
Let me know if either of these help.
