3.5 369 Relay Profibus Diagnostics
The diagnostic data available for the Profibus-DPV1 option matches Table CG–3: Profibus
Diagnostics on page CG–9. When no diagnostic information is available and the master
initiates a diagnostics read, the six slave mandatory bytes are read.
3.6 369 Relay Profibus-DPV1 Acyclical Communication
The following items have been made available through Profibus-DPV1 acyclical
communication. Data is addressed through the use of “slot and index” addressing. Three
parameters are required to read or write data from the 369 Relay using a Profibus-DPV1
master:
1. Slot number
2. Index number
3. Data length (number of 16-bit words)
