Setting Modbus Digital Inputs - Siemens SIPROCESS GA700 Operating Manual

6. Read out gas measured values of components: Display in display fields "Gas measured
value 1 to 5". The number of displayed gas measured values depends on the available
components. For additional information go to → [3.05.5] Communications (Page 223).
– The display is updated every time you start MODBUS communication.
– If a MODBUS TCP node is unavailable (communication status "stopped"), TAG, gas
7. Assign designation for external measured values:
– Each MODBUS node can receive up to two pressure measured values, two
– Use the corresponding parameter fields "Pressure 1/ 2", "Temperature 1/ 2" and/ or

Setting MODBUS digital inputs

Procedure
1. Main menu > "4. Communications" > "2. MODBUS TCP" >
"2. MODBUS TCP digital inputs"
The menu lists the up to eight MODBUS digital inputs that other MODBUS nodes can
use. The information in the navigation lines depends on the assigned function (pre-
selection) of the digital input:
