Limit monitor

Description
Any analog values (2 bytes/1 word) can be monitored
for limit overshooting or limit undershooting. The limit monitor issues the
"Limit" signal at its socket. In addition, limit monitors can be "marked"
according to their function. Example: Monitoring the individual sensor
measuring circuits of the temperature module (Temperature 1 - 3) for
overtemperature.
The limit monitor consists of:
• One analog plug
• One logic component
• One socket.
Overall, there are 4 limit monitors (1 to 4) available for BU2.
