Measured variables
2.3.1
Measured 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 configuration, several different readout types are available:
• Device display
• Modbus TCP
• Modbus RTU (via optional expansion module)
• Profibus (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.
