2.4.4 Fault indication with the discrete output
To indicate faults via the discrete output, set parameters as follows:
▪ Discrete Output Source = Fault
▪ Discrete Output Fault Action = None
Note
If Discrete Output Source is set to Fault and a fault occurs, the discrete output is always ON. The
setting of Discrete Output Fault Action is ignored.

The digital communications parameters control how the transmitter will communicate using digital
communications.
The Model 2700 transmitter with intrinsically safe outputs supports the following types of digital
communications:
▪ HART/Bell 202 over the primary mA terminals
▪ Modbus/RS-485 via the service port
Digital Communications Fault Action applies to all types of digital communications.
Note
The service port responds automatically to a wide range of connection requests. It is not
configurable.
