Relay outputs for the moduls 1, 2 and 3.
Explanations see prog.-no. 5890.
Sensor input for the moduls 1, 2 and 3.
Functions in addition to the basic functions will be possible by configuring the
sensor inputs BX21 and BX22.
Explanations see prog.-no. 5930).
Explanations see prog.-no. 5950.
Explanations see prog.-no. 5951.
The linear sensor curve is defined over two fixed points. The setting is made with
two parameter pairs for Function value and Voltage value (F1 / U1 and F2 / U2).
