I have added a DF1COM component in a form, and add somes controls like barlevels linked to this item.
plc is not connected to my computer but nothing append (no error messages and controls are not refreshed).
How can i know if communication with plc is ok? ComError seems to not working with this driver
Can i view communication exchanges? (send and receive messages)
A last question: if filldirection of my barlevel is left and value=0, i don't see value, is-it normal?
