SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
F_DP: actual cycle time %1 [ms] > , parameterized cycle time
%1 = actual F_DP communications cycle time
The actual F_DP communication cycle time is greater than the value
set using MD13320 $MN_SAFE_SRDP_IPO_TIME_RATIO. The para-
meterized communication cycle time is continually exceeded on the
PLC side.
Alarm display
NC start disable in this channel
Interface signals are set
Mode group not ready
NC stop for alarm
A STOP D/E is initiated (this can be set using MD10097
$MN_SAFE_SPL_STOP_MODE) on all axes with safety functionality.
Adapt the cycle time using MD13320
$MN_SAFE_SRDP_IPO_TIME_RATIO.
As a minimum, the value displayed in %1 must be set.
The selected cycle time has an effect on the runtime utilization of the
PLC module.
This must be taken into account in the setting.

F_DP: %1 communication, connection %2 signals SFC%3 error
%4
%1 = communication type
%2 = name or DP_DP_ID of the communication relationship
%3 = SFC block number
%4 = error detection
There is an F_DP communication error with the external communica-
tion partner. When attempting to access via the parameterized inter-
face, the PLC signaled an error.
The following displays are possible for communication type (%1):
-- F_SENDDP
-- F_RECVDP
As connection (%2), the name or the identifier (DP_DP_ID) of the
F_DP connection relationship is displayed.
Further, the PLC block (%3) is displayed, which identified an error, and
the error cause based on the error ID (%4).
This alarm can be suppressed using MD10096 $MN_SAFE_DIAGNO-
SIS_MASK, bit 2 = 1.
Alarm display
Check the PROFIBUS communication and the communication partner.
Check the parameterized logical basis address in MD13334/13344
$MN_SAFE_SDP/RDP_LADDR.
