CFIX
FUNCTION:
It defines a communication of 0, 1, 2 or 3 Fixed Words to be transmitted and/or received at every Bricks execu-
tion in RUN status. When this block is used, it defines the card as a client for this communication. The commu-
nication is enabled with the appropriate bit of the “SlaveMapLow” or “SlaveMapHigh” parameters. The Bricks
programmer will supply an instance of this Brick with the Slave ID, the number of words to be transmitted to
and/or received from the slave, the source and/or destination in FWA and the IVARS of the master to be trans-
mitted and/or received.
