A serial communication module optionally uses 2 channels. With the Channel number setting, you specify
the channel number (1 or 2) used to connect the 20-mA unit to the device. The communication module inputs
are labeled with the channel numbers.
Parameter: Slave address
•
Default setting (_:2311:106) Slave address = 1
Use theSlave address setting to define the device address of the 20-mA unit. If only one 20-mA unit is
connected to the serial bus, the default value
mA unit. The device address is important for distinguishing several 20-mA units that are connected to a serial
bus. Set an unambiguous device address on every 20-mA unit, for example, 1, 2 and 3 when connecting 3 of
the 20-mA units. On every 20-mA unit, set for the Slave address setting in the 3 functions 20-mA Unit
Serial the same device address for each.
Parameter: Unit
•
Default setting (_:13111:103) Unit = °C
You use the setting Unit to specify which physical unit of measurement the measured values represent. The
possible setting values are listed in the settings table.
Parameter: Conversion factor
•
Default setting (_:13111:104) Conversion factor = 100
The Conversion factor setting allows you to set the conversion factor for the measuring transducer.
Parameter: Resolution
•
Default setting (_:13111:108) Resolution = 0.1
The Resolution setting is used to specify the measured value resolution.
Parameter: Range active
•
Default setting (_:13111:107) Range active = false
If you do not activate the Range active setting (no x in the check box), the function operates over the
range 0 mA to 20 mA. The setting of the range for the scaled value goes from a usable range of 0 mA to 20
mA.
If you activate the Range active setting, then 4 additional settings Upper limit, Upper limit -
Sensor, Lower limit and Lower limit - Sensor appear.
Parameter: Upper limit, Lower limit, Upper limit - Sensor and Lower limit - Sensor
•
Default setting (_:13111:105) Upper limit = 20 mA
•
Default setting (_:13111:109) Upper limit - Sensor = 100
•
Default setting (_:13111:106) Lower limit = 4 mA
•
Default setting (_:13111:110) Lower limit - Sensor = 100
If you activate the Range active setting, then 4 additional settings Upper limit, Lower limit, Upper
limit - Sensor and Lower limit - Sensor appear. The setting Upper limit - Sensor is the
calculated measured value if the input current corresponds to the value in the Upper limit setting. The
setting Lower limit - Sensor is the calculated measured value if the input current corresponds to the
value in the Lower limit setting.
The following settings and information table shows only 1 of the 12 channels, as the setting possibilities of
the 12 channels do not differ.
