Signal Select the type of signal connected (current, voltage, etc.). The channel is switched off
if no signal type is selected (factory default).
Picklist: Switched Off, Current, Voltage, Resistance Therm., Thermocouple or
Mathematics.
Setting the mathematics functions:
Channels can be calculated with one another. The mathematics function can be selected
here instead of an analog signal. Here, the user can specify whether an analog signal is
attached or whether a calculation should be performed. Mathematics channels are
treated like "real" analog inputs, e.g. set points, totalizing. If mathematics is selected, an
analog signal can no longer be recorded there. If the device is a 3-channel device, analog
input 4 - 6 can be used as a mathematics channel.
!
Note!
Analog input 1 cannot be selected as a mathematics channel.
Range Select the input range or which resistance thermometer/thermocouple is connected.
The respective terminal layout can be found in the operating manual or on the rear of
the unit.
Connection
Only for "Resistance thermometer"
Specify whether RTDs are connected as 2-, 3- or 4-wire systems. Factory setting: 3-
wire
Channel Ident. Identifier for the measurement point connected to this input (e.g. "Pressure",
"Temperature", "Heater", ...). 10-character entry. Factory setting: Analog x
