General Communication Status - Communication Attempted Bit
Word 0, bit 1 – is the Communications Attempted status bit. When
RIO communication has been attempted with all configured devices,
this bit is set to 1. There are no further transitions of this bit until a
processor change of state occurs (i.e., Program mode to Run mode or
Test mode, or Test mode to Run mode).
Until this bit is set, all devices in M1 file word 10 (active device
status) appear to be inactive. This bit can be used to condition the
Enabled Device Fault bit. If the Communications Attempted bit is 1,
the Enabled Device Fault bit is valid.
