7.4 Errors on the SWD line
Different events can occur in conjunction with the SWD line, which require
rectification.
No SWD line present
If there is no connection between the SWD line and easy800-SWD, or if the
actual configuration has not found any station at all, the “STOP on SWD
error” device parameter determines how easy800-SWD is to respond:
•
“STOP on SWD error“ is activated: easy800-SWD switches to STOP.
The POW LED shows continuous green, Config LED shows continuous
green; SWD LED shows continuous red.
•
“STOP on SWD error“ is deactivated: easy800-SWD stays in RUN mode.
The POW LED flashes green, Config LED shows continuous green; SWD
LED shows continuous red.
Missing station: When is this an SWD error?
If easy800-SWD determines that an SWD station of the target configuration
is missing in the actual configuration, the PRSNT diagnostic bit is set to 0 and
the group alarm I13 is set to 1.
If the “All devices optional” device parameter has been clicked on
easy800-SWD, missing stations do not trigger an SWD error. The
“Mandatory station” device parameter, which can be set individually for each
SWD station, is no longer checked in this case. easy800-SWD stays in RUN
mode. The POW LED flashes green, Config LED shows continuous green;
SWD LED shows continuous green.
If the “All devices optional” device parameter has not been clicked on
easy800-SWD, the “Mandatory station” device parameter is checked for
each SWD station. If the missing SWD station is not a mandatory SWD
station, easy800-SWD stays in RUN mode and continues working with the
remaining SWD stations. The POW LED flashes green, Config LED shows
continuous green; SWD LED shows continuous green.
If the SWD station is mandatory, the SWD LED flashes red and the “STOP
on SWD error” device parameter decides how easy800-SWD is to respond
further:
•
“STOP on SWD error“ is activated: easy800-SWD switches to STOP.
The POW LED shows continuous green, Config LED shows continuous
green; SWD LED flashes red.
If this error occurs during operation, e.g. because a station responds too
late or is faulty, easy800-SWD switches directly to RUN mode as soon as
the error is rectified. A restart is not necessary.
•
“STOP on SWD error“ is deactivated: easy800-SWD stays in RUN mode.
The POW LED flashes green, Config LED shows continuous green;
SWD LED flashes red.
