Parameterizing The Profibus Interface (X101) - Siemens SINUMERIK 840Di sl Commissioning Manual

NOTICE
If the interface X102 is not networked with PROFIBUS, then it must at least be networked
with MPI, in order to enable the internal communication via SOFTMC. See Subsection
"Parameterizing the MPI interface (X102) (optional)" (Page 169)

Parameterizing the PROFIBUS interface (X101)

When you have inserted the 840Di sl Rack, the dialog box for assigning parameters to the
PROFIBUS interface (X101) opens automatically as for slot X2. Make the following settings
in the Properties box:
● PROFIBUS address of the DP master
● Subnet
● Equidistant DP cycle
● Equidistant time
Equidistant time
The set equidistant DP cycleis accepted in case of SINUMERIK 840Di sl as NC system clock
cycle and position controller cycle.
Position controller cycle = NC system clock cycle = equidistant DP cycle
The time you can set for the equidistant DP cycle depends on:
1. The cyclic communication load by the drives and field devices on the PROFIBUS DP
2. The capacity utilization of the cyclic position controller level by the NC due to the number
