GEMCAN SPECIAL FUNCTION
5.1 INTRODUCTION
The application interface to the GEMCAN I/O Scanner consists of P-Table configuration data and
a Special Function: CANCMD (T114). This function is only required when operating the
GEMCAN network with Masters operating in Change-over mode.
The Special Function validates the parameters supplied by the user and writes a report in the
function Status Word and Q rung output. If errors are detected during the validation phase, no
further action is performed by the Special Function and bit 15 of the Status Word and Q rung
output are set.
If no errors are detected the request is passed to the appropriate GEMCAN I/O Scanner module
and the Status Word and Q rung output updated. The GEMCAN I/O Scanner module actions the
request. The result of the request may be found by monitoring the respective Statistics in the F-
Tables.
WARNING
When using this software, the user program must include the correct use of
the diagnostic data to ensure that the data exchanged is valid, error-free and
current.
