○Output number assignment
Output data
: The output numbering refers to the solenoid position on the manifold and starts at zero.
: Standard wiring of the manifold is for double-solenoid valves and the output number starts at the A side and then B side in that
order as shown in the figure a.
If a single-solenoid valve is mounted on the standard wiring manifold, the output number for the B side valve is skipped.
: Custom wiring for mixed mounting single-solenoid valves and double-solenoid valves can be specified with a Wiring Specification
Sheet. Example wiring is shown in the figure b.
: Bit status "0" and "1" in the data corresponds to solenoid valve status OFF and ON (0: OFF, 1: ON), and the output number starts
at zero from LSB (least significant bit).
