Equidistant DP cycle TDP

Procedure
When the cyclic component of the DP communication is calculated, the DP master automatically
changes the value for the equidistant DP cycle to the minimum required time. This change must
be undone by re-entering the intended value for the equidistant DP cycle.
(SINUMERIK 840D sl)
Equidistant DP cycle
For SINUMERIK 840D sl, an ADI4 module is connected via an external PROFIBUS (connection:
DP1 (X126) or DP2/MPI (X136) ). The DP cycle - with constant bus cycle time - of the external
PROFIBUS must then be set the same as the position controller clock cycle parameterized in the
NC or the equidistant DP cycle of the internal PROFIBUS.
Note
The DP cycle of the external PROFIBUS must be the same as that of the internal PROFIBUS:
Equidistant DP cycle (external PROFIBUS) = position controller cycle = equidistant DP cycle
(internal PROFIBUS)
Connection to "NCU7x0.2 PN"
If an ADI4 module is connected to NCU module "NCU7x0.2 PN" then a module with the following
version and higher must be used: Article No. ...-0AA2
