tinuation
27305 F_DP: Parameter MD %1[%2] < > MD %3[%4]
Parameter %1 = MD name 1
%2 = MD field index for MD name 1
%3 = MD name 2
%4 = MD field index for MD name 2
Explanation An SPL connection with several SPL couplings (sub-slots) was parameterized, where different values are
entered in the F_DP communication parameters or the connection numbers (%1 and %3).
Note
SPL couplings (sub-slots) of an SPL connection are designated using the same values for:
● F_DP communication parameters
● SPL connection number
The following NCK machine data can be involved:
- MD13334/13344 $MN_SAFE_SDP/RDP_LADDR or
- MD13335/13345 $MN_SAFE_SDP/RDP_TIMEOUT or
- MD13333/13343 $MN_SAFE_SDP/RDP_CONNECTION_NR
- MD13338/13348 $MN_SAFE_SDP/RDP_ERR_REAC
- MD13349 $MN_SAFE_RDP_SUBS
Response Alarm display

tinuation
27306 F_DP: Max. number of active SPL connections (%1) for (%2) exceeded
Parameter %1 = maximum number of possible SPL connections
%2 = communication type
Explanation In the active parameterizing data sets for the specified communication type (F_SENDDP/FRECVDP), more
than the permissible number of SPL connections, designated using different IDs (MD13331/13341
$MN_SAFE_SDP/RDP_ID), were parameterized.
