Siemens SENTRON PAC4220 - 2.3 Measured Variables

2.3 Measured variables
2.3.1 Measur
ed variables
The total set of representable measured variables is restricted by the method of connecting the
device. The availability of the measured variables depends on the type of readout.
Depending on the device con󹪝guration, several di󹪜erent readout types are available:
• Device display
• Modbus TCP
• Modbus RTU (via optional expansion module)
• Pro󹪝bus (via optional expansion module)
• Web server
A measured variable that cannot be indicated due to the connection method is shown on the
display by means of a broken line "----".
The table below shows which measured variables can be displayed with each connection
type.
