4.4.4 Communication with the safety system
Communication with the safety system 4- Funktion_Kommunikation_Allg
Communication between the PSENvip and safety system is required if
you use tools that cannot be safeguarded in compliance with the stand-
ards (see section entitled "Tool shapes", under "Safety"). This is the
case with tool classes 2 and 3. User programs that do not support com-
munication with the PSENvip can be used if you only intend to safeguard
tools of tool class 1. This is the case with older versions of the PSENvip,
for example.
Communication between the PSENvip and the PLC safety system is
conducted via digital inputs and outputs. Some inputs and outputs on
the PSENvip have another function compared to normal mode.
Communication only occurs in the system status TEST. This status is
adopted
 After power-up.
 After a tool change.
 After a 0/1 pulse edge at the input System-Init.
 Periodically every 2 minutes.
