There is also a possibility of registering ERRC occurrences in event
loggers by connecting the ERRC output to the ERROR PC element,
which adds a time stamp to the event and stores it in the event logger.
From there, the time stamp and the ERRC value can be observed with
Drive
Window or the CDP 80 panel (first two digits of the error code are
converted to descriptive text, the last two digits are shown numerically).
However, usually the ERRC pins are monitored with FCB, using its
online mode and dynamic measurement features. It is also customary
to use FCB to assert the RESET input pins temporarily to “1” with its
“forcing function”.
It is highly recommended to connect the ERR pin to some logic PC
elements of the application itself instead of having them checked
sporadically by the application designer or service personnel. In most
applications, an “ERR = 1” status indicates that the respective function
is not safe to use and should therefore not be used at all. However, it is
the application designer’s responsibility to write the program so that the
“ERR = 1” status is handled the correct way (e.g. the system is stopped
in a controlled manner). The AC 80 system does not register or react to
ERR signals in any way. For the system program, ERR signals are
ordinary, quite like any other output signals from the PC elements.
Using DriveDebug Drive Debug is a Windows-based diagnostic tool for devices that use
the DDCS communication protocol. These devices include e.g. the
AC 80 and the ACS 600. Drive
Debug can be used for e.g. monitoring,
trending and adjusting user-selectable memory locations.
The Drive Debug User’s Manual is included in the AC 80 Software
Package (directory Drideb) as DRIDEB.DOC.
