I've spent a fair bit of time searching the docs for a way to aggregate pin values into a total. This is desired as my mb2hal configuration ends up with an error count for each type of transaction. The VFD I am using is a Stepper online EV200 (Similar to a Mollum) that only supports functions 0x03 and 0x06. I have the interface working pretty well and using the QtDragonHD ui. I get one pin for modbus errors with QtDragon. I can either drop into some programming on the Qt side or use some slight of hand to aggregate all of the different transaction errors. I thought I would find an add2 component, but that doesn't seem to exist. I would really appreciate a pointer to a technique or capability to handle this. The files are in a state of flux so sorry about the lack of organization...
Thanks in advance,
Bill
