The Manual Management menu allows the user to manually control the I/O
of the controller. The user can manually input values for the analog inputs
and digital inputs. The user can also manually control the analog outputs
and digital outputs. EXTREME CAUTION should be used when manually
controlling the I/O. It is highly recommended that manual control of the I/O
is done only with factory assistance. The controller’s safeties and lockouts
are bypassed by this manual management and should only be used as
a troubleshooting feature. If the controller is powered down, I/O Manual
Management is reset to off. Therefore, if using this troubleshooting feature, the
best way to clear manually input values is to power down the controller.

details.
