DIGITAL SENSOR PARAMETERS
Sensor: 01
Input No.: 00003
Status, normally open: yes
Text: abcdefghi
Sensor (00 ... 20): digital sensor number to be config-
ured.
Input No.: digital input where the sensor is connected.
See section 6 ‘Input and output coding’.
Status, normally open (Yes ... No):
• yes: the sensor marks ‘ 1 ’ when there is continuity
between CD and the corresponding input.
• No: the sensor marks ‘ 1 ’ when there is no continui-
