PROFIBUS DP

10. PROFIBUS DP
This chapter contains all necessary information to operate the PROFIBUS gate-
ways in a PROFIBUS DP network.
Information!
The respective bits ground fault, overvoltage, noise, double address will only be set if
AS-i masters are used, which also support these functions.

Diagnostics

EC-flags (high) and AS-i watchdog:
EC-flags (low):
List of AS-i slaves with configuration error
Delta list:
List of AS-i slaves with periphery fault
LPF:
Each element of the user diagnostics (ec-flags and slave lists) can be switched off
by setting the appropriate bit in the parameter telegram.
ExtDiag will be set if at least one of the following conditions is fulfilled:
ConfigError ≡ 1
•
APF ≡ 1
•
PeripheryFault ≡ 1
•
bit 0: periphery fault
bit 1: ...
bit 2: failure 24 V (option safety monitor)
AUX
bit 3: failure redundant 24 V AUX (option single master)
bit 4: earth fault
bit 5: over voltage
bit 6: noise
bit 7: duplicate address
bit 0: configuration error
bit 1: slave with address '0' detected
bit 2: auto_address_assignment not possible
bit 3: auto_address_assignment available
bit 4: configuration mode active
bit 5: not in normal operation
bit 6: AS-i power fail
bit 7: AS-i master offline
1: ConfigError
0: no ConfigError
1: periphery fault
0: no periphery fault
