Subject : communication error on debugger: "overrun"

Keywords: Communication - error - debugger - overrun


Concerning communication between ISaGRAF debugger and target:

The error message "OVERRUN" indicates a synchronization error while

receiving characters (on debugger side). This generally corresponds

to a character received on the RS line before the preceding one is

read by the debugger. This can appear under Windows 3.1 if the

system is blocked (ex: some mouse manipulations).

This is a non severe error, due to the system behavior, and not due

to the safety of the communication link.

Intermediate states "disconnected" or "appli XXX active" are the

normal re-connection procedure run by the ISaGRAF debugger after any

communication error.
