4.3.4 Start devices
In the course of the analysis, after all monitoring, logic and EDM devices have been processed,
the result of the AND link of all device states is determined for each OSSD. In the start devices,
this result is analysed together with a possible start condition.
For each independent OSSD, at least one start device is required. If multiple start devices are
present in an OSSD, they are linked with one another by means of an OR function. Thus, for
the validation of an OSSD, it is sufficient when one of the start devices fulfils the condition for
the validation.
Possible start conditions are:
Automatic start (no additional start condition)
Monitored start by means of an AS-Interface standard slave
Monitored start by means of start input on the AS-Interface safety monitor
Monitored start by means of a safe AS-Interface slave
Activation via standard slave
Activation via monitor input
Note
A start device can only be assigned to one OSSD. If, for example, both OSSDs are to be star-
ted with one button, a start device is to be configured for each OSSD. Both of the devices, ho-
wever, use the same button.
