(1) Modifying bit values is not supported by all controllers. Refer to your controller manual for details.

TIP

Status bits for a particular channel reflect the configuration
settings for that channel. To receive valid status, the
channel must be enabled and the module must have stored
a valid configuration word for that channel.
