Programming
The channel type and the display value can be configured.
The channel type has to be chosen between voltage (-/+ 10 V), current (0-20mA or 4-20mA) or
temperature measurement (Pt100 or Pt1000 2, 3 or 4 wires). This configuration is selected
channel by channel with the position of a dip switch, the push button on the front plate or by
the user program.
The display value can also be configured. The scale and the position of the dot can be
modified. Therefore, it is possible to display a process data, i.e. Pressure, speed, etc.
It is also possible to change the filtering : the choice is 50hz, 60Hz, integration or standart

4.3.1. Hardware configuration

Dipswitches on the left side of the extension have to be set on the right position.
