UM344-2

4.3.3.1 Analog Mode

ŸThe Transmitter outputs a 4-20 mA signal for input to devices such as controllers and recorders.

ŸAnalog operation employs a Point-To-Point Network comprising a Transmitter, Primary/Secondary Master, and other non-signaling devices. Transmitter short address is 0 (zero).

ŸUse the optional Digital Meter for local indication of transmitter output.

ŸThe Transmitter is factory configured for analog mode unless otherwise ordered.

ŸUse an MXC for configuration, diagnostics, and reporting the current process variable.

4.3.3.2 Digital Mode

ŸThe number of Allowable Network Elements is: Primary and Secondary Masters - 1 each Transmitters - 1 to 15

ŸThe process variable is transmitted digitally. The analog output of each transmitter is "parked" at 4 mA.

ŸThe HART communication source can be a Primary or Secondary Master. A Primary Master can be used for data acquisition, maintenance, or control purposes. A Secondary Master, the MXC for example, may be used for configuration, diagnostics, and reporting current process variable.

ŸUse the optional Digital Meter for local indication of transmitter output.

ŸPlace the transmitter in the digital mode by assigning it a SHORT ADDRESS from 1 to 15 when configuring the TRANSMITTER ID BLOCK with the MXC (see Section 5).
