Configuring the Alarms
Alarms allow the user program in the S7-200 CPU to initiate interaction with the operator by
displaying an alarm message on the TD device. When your user program sets an alarm bit,
the TD device reads the text of the alarm from the S7-200 CPU.
The figure below lists the key tasks for creating alarms. You configure the following
information for each alarm:
● Number of alarms: Up to 80 alarms for the TD 200, TD 200C and TD400C, and up to 40
alarms for the TD 100C to be configured for the TD device
● Text message for the individual alarms
