The following explains how to turn a bit device ON/OFF.
Note that this operation can be performed only when the display format is "Vertical".
POINT
If a communication error has occurred during connection, make connection target
setting again.
Danger
When controlling (data change) a running C Controller module
connected to a development environment (personal computer),
configure an interlock circuit in the user program so that the whole
system will function safely all the time.
Also, before performing any other controls (operating status change
(status control)) to the running C Controller module or handling the
development environment (personal computer), configure an
interlock circuit in the user program to ensure the safety of the whole
system.
In these controls, especially, the one from an external device to a
remote C Controller module, the C Controller module side problem
may not be resolved immediately due to failure of data
communications.
To prevent this, create an interlock circuit in the user program, and
establish corrective procedures for communication failure between
the external device and C Controller module.
1)Double-click the bit device No. whose ON/OFF status is to
be changed.
2) To accept the change, select in the dialog box.
Select to cancel.
