B3.4 Operation
Once you have completed the setup described in Sections B3.1, “Setting Controller
Parameters,” B3.2, "Setting I/O Parameters," and B3.3, “Setting Operation Parameters”,
the module is ready for operation. Start module operation in manual or automatic mode
by writing to the RUN/STP and A/M/C registers. To operate in Manual mode, specify an
output level using the Manual Output (MOUT) register.
For information on SP number selection, remote set point, and other operation control
functions, see Section C7, "Operation Control."
