Connection of Alarm Relays
The selection of a signal transmitter for the
watchdog alarm is optional. It is recommended
that a switch for turning off the alarm be
provided.
NOTE:
Terminal 69 is used to control the module MCE
3, only. The digital output cannot be used for a
relay.
Normally Open/Normally Closed Attribute
Beginning with V2.04.00 firmware, the point attribute NO/NC defines the relation
between the physical states (contact position and relay ON/OFF, respectively) at the
digital inputs and outputs and their logical status; see also Table 8 and Table 9.
Table 8. Digital input parameters
