5. If T
o
= (T
DP
- 125 μs)
Then for T
i
, the following must apply: T
i
> 3 * 125 μs
6. If T
o
= (TDX + 125 μs)
Then for (T
i
+ T
o
), the following must apply: (T
i
+ T
o
) ≠(T
DP
+ 125 μs)

Typical parameter values
Equidistant DP cycle (T
DP
) 2.000 ms 3.000 ms
Actual value acquisition (T

) 0.250 ms 0.250 ms
Setpoint acceptance (T
o
) 1.250 ms 1.000 ms
Note
ADI4 DP slaves
• Order no.: 6FC5 211-0BA01-0AA0
• Order no.: 6FC5 211-0BA01-0AA1 or …-0AA2
exhibit a different behavior for a parameter assignment for actual value acquisition (T
i
) and
setpoint acceptance (T
o
) deviating from the boundary conditions indicated above.
• ADI4 DP slave with order number ...-0AA0
If parameters are assigned that deviate from the boundary conditions indicated above,
they are ignored by this ADI4 DP slave, as parameters are fixed internally. The ADI4 DP
slave establishes cyclic communication with the DP master using the preset values (and
not the assigned parameters) without an error message.
• ADI4 DP slave with order number ...-0AA1 or ...-0AA2
If a parameter assignment that deviates from the boundary conditions indicated above is
downloaded to this ADI4 DP slave, the ADI4 DP slave does not establish cyclic
communication with the DP master.
