5.2.5.4 Logical Channel Assignment
E981.07
The Logical Channel field is used to address one of the six possible satellites connected to the two physical
channels of the 981.07. Each physical channel can support up to three satellites. Each of these three satellites
is assigned to a separate time slot on the bus. Each time slot has a appropriate sensor data register (A, B, C).
The 981.07 response to requests for undefined physical channels with an error message with the CNC bit is set
(CNC=1). This illustrated in the table below.
