FORCED ACTIVE Mode
The module is in FORCED ACTIVE mode when you set ACTIVE mode
from the AbRioCfg program. FORCED ACTIVE mode lets you send
and receive data without having to create messages in the module. It
is intended primarily for setting up and testing RIO networks.
If you try to download a configuration when the module is in
FORCED ACTIVE mode, AbRioCfg software asks if you want to take
the module out of ACTIVE mode. If you click OK, AbRioCfg software
changes the mode, downloads the configuration, then puts the
module in INACTIVE mode.
IMPORTANT
When the module is in FORCED ACTIVE mode, the RIO network
is in run mode.
