DMC-18x6 Command Reference

OP
FUNCTION: Output Port
DESCRIPTION:
The OP command sends data to the output ports of the controller. You can use the output port to
control external switches and relays.
ARGUMENTS: OP m,a,b,c,d
where
m is an integer in the range 0 to 65535 decimal, or $0000 to $FFFF hexadecimal. (0 to 255 for 4
axes or less).
m is the decimal representation of the general output bits. Output 1
through output 8 for controllers with 4 axes or less. Outputs 1 through output 16 for controller
with 5 or more axes.
a,b,c,d represent the extended I/O in consecutive groups of 16 bits, (values from 0 to 65535).
Arguments which are given for I/O points which are configured as inputs will be ignored.
The following table describes the arguments used to set the state of outputs.
