Integrating external pressure sensor via MODBUS TCP

Requirements
The following requirements must be met before you can connect an external pressure
sensor via MODBUS TCP:
● MODBUS node(s) is/are configured: → Setting communication via MODBUS TCP
(Page 248).
● MODBUS communication is active.
Procedure
1. Component > Main menu > "2. Settings" > "11 Pressure sensor selection"
The currently set signal source and the currently measured pressure are displayed.
2. Set the signal source: "Signal source" parameter field.
– Authorize access with the Expert PIN, if necessary.
– Select "MODBUS TCP" setting.
3. Select an external communication partner: "MODBUS node" parameter field.
The selection list contains all MODBUS nodes (servers) which have been activated for
communication.
4. Select required pressure value P1 or P2: "Measured value" parameter field.
5. Repeat steps 1 to 3 for the other analyzer modules if two analyzer modules are installed
in your device.
The pressure value of the signal source can also be returned via an analog input instead
of MODBUS TCP or be created device-internal:
→ Using device-internal pressure sensor (Page 181). In this case, no further signal source
settings are required.
→ Integrating external pressure sensor via analog inputs (Page 182).

Integrating external pressure sensor via analog inputs

Requirements
The following requirements must be met before you can connect an external pressure
sensor via an analog input:
● Option module 2.2 is installed.
● Pressure sensor is connected correctly.
● SIPROCESS GA700 analog inputs are configured accordingly.
