txBundle. Implemented by counting transitions
to 0 of txPosition.

txPosition
Description
Transmission permission position. 0 indicates no transmission either because the conductor has not
granted permission (due to bandwidth constraints or bundle conflict) or
txBundle is set to 0. Valid
values are 0 through the number of bundles active on the network. A value of 1 indicates the
transmitter has the highest priority on the network and will be the last to be dropped if bandwidth is
exhausted.
