5.2.1.1 PASS_ON
With the variable PASS_ON = 1 a passivation of the safety-oriented data of the
CD_75_-EPN E/A safety module can be activated, e.g. depending on defined
states in the safety program. The passivation is not performed directly in the
measuring system, instead the status of these variables is registered by the F-Host
and the passivation is only activated by means of the safety program data. Cyclical
data are still output by the measuring system!
If a passivation is performed with PASS_ON = 1, the preset adjustment function is
switched off.
5.2.1.2 ACK_NEC
The official application of this variable would be an operator acknowledgment for the
measuring system after F-I/O faults. However, for the measuring system no process is
defined, for which this procedure is permissible. For safety reasons these faults must
be removed first and then the supply voltage must be switched OFF/ON.
