Errors during DP Start-up
If an error occurs in the parameterisation (UserPrmData) or configuration (CfgData) during DP start-up, this is
indicated both through the fieldbus LEDs and in the diagnostic data (DiagData).
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
argument
Description
1 The Reaction to DP error cannot be set to "Outputs unchanged" in synchronous mode
2 The DPV1-MSAC_C1 connection has been activated by the master, but no DPV1-
MSAC_C1 connection is defined
6 The Multi-configuration mode is not allowed if Checking the CfgData is switched off
8 Synchronous mode may only be activated when at least one DP output byte is
configured
10 The optimised input cycle is only possible in synchronous mode
11 The length of the DP buffer exceeds the size of the DP RAM in the PROFIBUS ASIC
12 Fast-FreeRun mode may not be activated together with synchronous mode
Errors when checking the CfgData
Error code 2
Error code 2 indicates that a byte in the CfgData is not correct. The error argument describes which CfgData byte has
been detected as containing an error (the offset of the faulty byte + 1).
Error code 5
Error code 5 indicates that the length of the digital outputs (in bytes) calculated from the CfgData is not correct. The
error argument contains the expected byte length.
Error code 6
Error code 6 indicates that the length of the digital inputs (in bytes) calculated from the CfgData is not correct. The
error argument contains the expected byte length.
