5.8. WFIX: WRITE FIXED WORD
SYMBOL:

WFIX
FUNCTION:
This block is used on the server device to write the value from a defined xVAR to one (or two) Fixed Word (s). Note
that the client reads from the server only in the FWA and not in the xVAR area. The type of var to be read is an
input. It is possible to select integer type for IVAR or float type for VAR (in this case 2 words of FWA will be
written).Note that this Brick acts internally to the slave DGFC, and no DeviceNet communication is involved.
