RFIX
FUNCTION:
This block is used on the server device to read one (or two) words of FWA and to write the value in a defined
xVAR. Note that the client is able to write only in the FWA of the server. The type of var where the value is to be
copied is an input. It is possible to select integer type for IVAR or float type for VAR (in this case 2 words will
be read) .Note that this Brick acts internally to the slave DGFC, and no DeviceNet communication is involved.
