Technical Information
PIN Functions
Software program on PC or PLC can use the same ASCII protocol
described below for human interface for doing automatic control and
monitoring of the controller.
Every 500 msec, if the controller is in Report mode (default), all the 3
Report strings made of 30 characters each, corresponding to the
3 HV channels are sent by the IPCU.
The string is always made of 30 characters for each HV channel
(independently by the channel status).
A transmission from the external PC, turns the IPCU to the
Command Mode
To go back to the Report Mode complete the command string with
CR (0x0D) or ESC (0x1B).
Every single received character is Echoed back in order to allow a
control by the operator.
