Final parameterization of the equidistant DP slaves

7-238
After all the planned DP slaves have been inserted into the configuration and
parameterized individually, the following parameters of the equidistant DP
slaves are set in two separate steps for final parameterization of the equidistant
DP communication:
Step1:
S
Enabling of the equidistant DP cycle
S
Master cyclic portion T
Step2:
S
Equidistant DP cycle T
S
Master application cycle T
S
Actual-value sensing T
S
Setpoint acceptance T
An overview of the various times of a DP cycle is shown in Fig. 7-2, page 7-205.
Note
The procedure of final parameterization of equidistant DP communication is
exemplified by one DP slave 611U. For other equidistant DP slaves, e.g. SIMO-
DRIVE POSMO SI, CD/CA; ADI4; etc., proceed analogously.
Notice
If a project you want to perform final parameterization on contains DP slave
ADI4 interfaces, please observe the boundary conditions for the following pa-
rameters:
S
Equidistant DP cycle T
S
Master cyclic portion T
S
Actual-value sensing T
S
Setpoint acceptance T
