Page 5 of 27
3.1.3.2 Pressure and Temperature Transmitters
The FGM 160 can be configured to accept analog 4-20 mA transmitters or HART compatible
transmitters. The pressure and temperature transmitters may be omitted if the system is
configured to get the pressure and temperature data from the DCS system (Modbus
communication link).
3.1.4 Output Signals
3.1.4.1 Modbus Communication (RS-485)
The FGM 160 has two separate Modbus communication ports.
One is dedicated for communication with a DCS system. The second is a service port for
configuration and monitoring of the FGM 160 system.
In the FGM 160 Foundation Fieldbus configuration, DCS Output is disabled.
3.1.4.2 Foundation Fieldbus Output
A maximum of four (4) parameters can be predefined according to customer requirements.
The list of parameters available for the customer can be found in Fluenta AS doc. No.
72.120.305 (all parameters available by using Modbus Serial Interface are accessible using
Foundation Fieldbus output).
3.1.4.3 Current Loop Outputs
Up to six (6) current loop outputs are available for output of selectable parameter values, where
three (3) analog outputs are configured as the default. The 4-20 mA current loop output
channels can be configured as active or passive outputs.
4-20 mA Outputs are replaced by FF Outputs in FGM 160 Foundation Fieldbus Configuration.
3.1.4.4 HART Output
One of the current loop outputs can be also configured for HART output communication. Refer
to HART Output Interface Specification [5] for details.
3.1.4.5 Pulse/Frequency Output
The FGM 160 can be also configured to provide a pulse or frequency output signal. The pulse
output will represent an incrementation of the totalizer (of e.g. volume or mass), whereas the
frequency output will represent a process parameter (e.g. volume flow rate, mass flow rate
etc.)
