6.2.2 Errors during DP Start-up
If an error occurs in the paramétrisation (UserPrmData) [}35] or configuration (CfgData) during DP start-up,
this is indicated both through the fieldbus LEDs [}61] and in the diagnostic data (DiagData) [}64].
Possible DP start-up errors are identified by an error code and an error argument.
Errors when checking the UserPrmData
Error code 1
Error code 1 indicates that a reserved bit in the UserPrmData has been set to an incorrect value, or that the
function corresponding to the bit in the UserPrmData is not supported. The error argument describes which
UserPrmData byte has been detected as containing an error (the offset of the faulty byte + 1).
Error code 3
Error code 3 indicates that a combination of functions selected in the UserPrmData is not allowed. The error
argument describes the impermissible combination.
Error code argu-
ment
Description
1
The Reaction to DP error [}53] cannot be set to "Outputs unchanged" in synchronous
mode [}69]
2
The DPV1-MSAC_C1 connection [}56] has been activated by the master, but no DPV1-
MSAC_C1 connection is defined
6
The Multi-configuration mode [}73] is not allowed if Checking the CfgData is switched
off [}73]
8
Synchronous mode [}53] may only be activated when at least one DP output byte is
configured
10
The optimized input cycle [}53] is only possible in synchronous mode [}53]
11 The length of the DP buffer exceeds the size of the DP RAM in the PROFIBUS ASIC
12
Fast-FreeRun mode [}53] may not be activated together with synchronous mode [}53]
