Byte 4 (Min. Station Delay Responder)
This is the time that the DP slave must wait before it is allowed to send its
response frames to the DP master, unit: bit times.
Bytes 5 and 6 (Ident_Number)
This number is assigned by the vendor. The DP slave only accepts parameter
assignment frames when the Ident_Number transferred with the parameter
assignment data matches its own Ident_Number. The value is transferred in
Motorola format, in other words, the higher order half is in byte 5.
Byte 7 (Group_Ident)
With this parameter, a group can be formed for the DP_global_ctrl() function. Each
bit represents a group. The Group_Ident is accepted only when the Lock_Req bit is
set (see byte 1).
Byte 8 (DPV1_Status_1)
Bit Meaning
7
DPV1_Enable
This bit is set to activate the DP-V1 functionality of a DP-V1 slave. If
the bit is not set, the slave operates in the compatibility mode
whenever possible.
6
Fail Safe
This bit is set to show that the slave operates in the fail-safe mode.
5-3 reserved
2
WD_Base_1ms
If this bit is set, the watchdog time is calculated according to the
following formula:
T
WD
[ms] = WD_Fact_1 * WD_Fact 2
If the bit is not set, the watchdog time is calculated as follows:
T
WD
[ms] = 10 * WD_Fact_1 * WD_Fact 2
1 to 0 reserved
