Hi Michael_P,
Problem solved, thanks for the info.
I was scared, had spent several hours making a program for a V130, and suddenly happended the above issue.
Now I can continue debugging the program.
Conecting to a VFD using MODBUS, the V130 will send all the params to the VFD, and will read all the information params that can be read from the vfd, and display all the info on V130 screen, also reading of a water level sensor. Now struggling to make graphs of the variables readed, including water level, DC bus voltaje, amperaje, power, alarms, params.
Happy with Mr V130.
All the best,
