12. Appendix E: Profibus-DP Data and Diagnostics
For the LUFP7 gateway default configuration, the following response is received from the TSX PBY 100 coupler:
Bytes | Name | Value |
0 | Configured | 16#01 |
1 | Operating | 16#01 |
Number of %IW | 16#0010 | |
Number of %QW | 16#0010 | |
6 | Input data size | 16#20 |
7 | Output data size | 16#20 |
Bytes | Name | Value |
8 | Diagnostic data size | 16#06 |
9 | Compact diagnostic | 16#00 |
10 | Diagnostic counter (1) | 16#0A |
11 | Exchange counter (1) | 16#02 |
12 | Unavailability counter (1) | 16#03 |
13 | Invalid response counter (1) | 16#02 |
(1)The values of all four counters vary while the coupler and gateway are operating. These are modulo 256 counters, i.e. their values loop back from 255 to 0.
