The following parameterizing data sets are obtained:
1. SPL connection (sub-slot 1)
$MN_SAFE_SDP_ID[0] = 2000
$MN_SAFE_SDP_NAME[0] = WZM1
$MN_SAFE_SDP_CONNECTION_NR[0] = 1
$MN_SAFE_SDP_LADDR[0] = 288
$MN_SAFE_SDP_TIMEOUT[0] = 0.5
$MN_SAFE_SDP_ASSIGN[0] = 001004
$MN_SAFE_SDP_FILTER[0] = 1111
$MN_SAFE_SDP_ERR_REAC[0] = 0
2. SPL connection (sub-slot 2)
$MN_SAFE_SDP_ID[1] = 2000
$MN_SAFE_SDP_NAME[1] = WZM1
$MN_SAFE_SDP_CONNECTION_NR[1] = 1
$MN_SAFE_SDP_LADDR[1] = 288
$MN_SAFE_SDP_TIMEOUT[1] = 0.5
$MN_SAFE_SDP_ASSIGN[1] = 033036
$MN_SAFE_SDP_FILTER[1] = 8888
$MN_SAFE_SDP_ERR_REAC[1] = 0
Note
All machine data of a parameterizing data set are linked with one another using the common
machine data index.
MD13331 $MN_SAFE_SDP_ID: Identifier of the SPL connection
Every SPL connection must be assigned a freely selectable, unique identifier (DP_DP_ID),
however, this must be unique across all F-CPUs that are connected using F_DP
communication.
MD13332 $MN_SAFE_SDP_NAME: Connection name
An SPL connection can be given a freely selectable connection name with a maximum of 15
characters using MD $MN_SAFE_SDP_NAME. The connection name is displayed at the HMI
and in the alarm display. If a connection name has been assigned, then for alarms 2735x, the
name is displayed; if a name is not displayed, then the corresponding DP_DP_ID identifier is
displayed.
The connection name does not have to be specified in all of the parameterizing data sets
associated with an SPL connection. The connection name is always used that is specified in
the first active parameterizing data set, i.e. the parameterizing data set with the lowest machine
