Explanation of the process data
Appendix B: Explanation of the process data
NOTE
The addresses shown in the tables in Appendix B use 0-based addressing. The Productivity Suite soft
-
ware uses 1-based addressing. So, add 1 to any address in these tables when accessing these values in
Productivity Suite.
Digital Input
The order of the digital input data depends on the configuration parameter “Pin_Port_based_IO_Layout”.
This is explained in the following tables:
