The settings for start-up mode are located in byte 3 of the User_Prm_Data
(the default settings are printed bold):
Bit no. Description is supported by
Bit 0/1 Start-up mode
0: Process data exchange
1: Parameter mode
2: Parameter mode with Stat_Diag BK3500
DPV1 settings
More details regarding the DPV1 services will be given in a later chapter
(DPV1). In order, however, to be able to use the DPV1 services with the
DP master that is also executing the cyclical data exchange (class 1
master), DPV1 functionality must be switched on.
A new diagnostics format is also described in the DPV1 standard that can
be activated in place of the diagnostic formats used formerly. The structure
of the diagnostic data for both formats is described in detail in a later
chapter (Diagnostics).
The DPV1 settings are located in bytes 0-2 of the User_Prm_Data (the
default settings are printed bold):
Bit no. Description is supported by
Byte 0
Bit 7 DPV1 service (class 1)
0: are not supported
1: are supported BK3x10 / BK3500 / LC3100
Byte 2
Bit 3 Diagnostic format
0: old format
1: DPV1 format BK3x10 / BK3500 / LC3100
Multi-Master Operation
It is possible with the DPV1 services to access the terminals acyclically. In
order to avoid access conflict with the cyclical data exchange, a decision
can be made for each terminal as to whether it can be accessed by means
of the cyclical data exchange or acyclically via the DPV1 services.
The assignments of the terminals are located in bytes 15-31 of the
User_Prm_Data (the default settings are printed bold):
Bit no. Description is supported by
Byte 15
Bit 0/1 Assignment for terminal 1
0: DP data exchange
1: acyclical DPV1 services BK3x10 / BK3500 / LC3100
Byte 15
Bit 2/3 Assignment for terminal 2
0: DP data exchange
1: acyclical DPV1 services BK3x10 / BK3500 / LC3100
... Assignment for terminal i
0: DP data exchange
1: acyclical DPV1 services BK3x10 / BK3500 / LC3100
Byte 31
Bits 6/7 Assignment for terminal 64
0: DP data exchange
1: acyclical DPV1 services BK3x10 / BK3500 / LC3100
If no User_Prm_Data are transmitted, the bus couplers adopt the most
recently programmed value. If the bus coupler does not support any
particular setting, then the default value is set at the coupler.
