Description
Participation flag
When a Slave Unit participates in the network, the bit
corresponding to the node address will be on.
Once the target Slave Unit is participating, the bit remains on. It
stays on even the Slave Unit separates due to a
communications error.
Communications
error flag
The bit will be on if a communications error occurs to the once
participated Slave Unit whose participation flag is on, and its
communications with the CompoNet Master Board is
prevented. The bit will be off when the error is resolved.
