PROFIBUS-DP 5.4
Communications 5-219
Mode for details on using this register and the differences between these two sub-modes.
The order of the input registers for an n-axis module with a Sensor DI/O running in Compact
Mode with Sync is shown below. I represents the RMC’s input base address. If your module does
not have a Sensor DI/O, drop the last two registers:
Number
Specified by command for axis 0
Specified by command for axis 1
Specified by command for axis n
Sensor DI/O Inputs 0-15 (if present)
Sensor DI/O Inputs 16-17, Outputs 0-7 (if present)
The following chart shows the same for an RMC running in Compact Mode without Sync:
Number
I + 0 Status for axis 0
I + 1 Specified by command for axis 0
I + 2 Status for axis 1
I + 3 Specified by command for axis 1
: :
I + 2*n + 0 Status for axis n
I + 2*n + 1 Specified by command for axis n
I + 2*n + 2 Sensor DI/O Inputs 0-15 (if present)
I + 2*n + 3 Sensor DI/O Inputs 16-17, Outputs 0-7 (if present)
