Writing to Contact Outputs of Slaves
To output to slave contacts, use a WRITE instruction (Special Module Write). Data is
written in (16-bit) word units.
Special Module Write
WRITE s sl n2 k
s : First device number storing data to be written to slave contact outputs.
sl : Slot number where F3LA01-0N is installed.
n2 : First data position number for writing ( n2=103 - 118)
k : Transfer size in words (number of word (16-bit) units to be transferred)
The table below shows the mapping between slave addresses and contact output data.

Note: I/O number for output 3 cannot be used for a V2.1-compatible slave because output 3 is used by the system for
selecting Slave B. (any data written to output 3 is ignored).
TIP
- Data in the above table maps to slaves with addresses 1A-31A and 1B-31B. A '—' character
indicates no mapping to any slave.
- Each bit position in the above table maps to a contact output with I/O number between 0 and 3 on a
slave. A bit is 1 if its corresponding contact output is to be turned on and 0 if its corresponding
contact output is to be turned off.
- Up to 4 contact outputs (4 bits) are represented for each V2.0 slave. Up to 3 contact outputs (3 bits)
are represented for each V2.1 slave.
