Configuration on PCD3.T760 RIO Module
When the PCD3.W745 is used on PCD3.T760 RIO station, 6 registers are available
in the Profi S-IO or Profibus DP configurator.
The 2 first registers (anal_16 , anal_17) contain the diagnostic bits of the 4 inputs
channels.
The first 2 bytes (low bytes) gives the diagnostic bit of 2 analog channels (1 byte per
channel) as indicated in the following screenshot:
Channel 0
Channel 1
Channel 2
Channel 3
Signification of each 8 bits (from right to left) as explained in chapter 3.2.
