A 14 Startup and restart
A 14.1
Startup/restart following power up
The module starts up once the configuration and parameterization data record has been
downloaded successfully and the internal tests have been completed without errors.
A 14.2
Restart after triggering a safety function
The VersaSafe system resets a safety-related output to "1" automatically when the safety
function trigger is reset.
A 15 Memory sizes for the safety logic
The maximum size of the safety logic is 20 kB.
The following guide values can be used as a basis for creating your safety logic:
– Size of the first instance of each block: 800 bytes
– Size of each additional instance: 300 bytes
– In the mix calculation, both of these values include a reserve for various other logic
operations (AND, OR, NOT, etc.).
For the actual size of the data record, please refer to VersaConf Safety. If the safety logic
limit has been exceeded, a corresponding error message is displayed by VersaConf
Safety. In this case, reduce the size of your safety logic.
WARNING: Unexpected machine startup
If you do not want the machine to start up/restart automatically, configure the safety logic
accordingly.
