Input group I0 (IN0...IN3)
These inputs are a group of multifunction channels.
These inputs can be used as follows (each input separately configurable):
• analogue input 0...20 mA
• analogue input 0...10 V
• analogue input 0...32 V
• voltage measurement ratiometric 0...1000 ‰
• binary input plus switching (BL) for positive sensor signal (with/without diagnosis)
• binary input minus switching (BH) for negative sensor signal
• fast input for e.g. incremental encoders and frequency or interval measurement
Possible operating modes inputs/outputs
→ chapter
Sensors with diagnostic capabilities to NAMUR can be evaluated.
All inputs show the same behaviour concerning function and diagnosis.
Detailed description → chapter
Configuration of each input is made via the application program:
INPUT
• FB (→ page 173) > input MODE
FASTCOUNT
• FBs (→ page 169),
>
If the analogue inputs are configured for current measurement, the device switches to the safe
voltage measurement range (0...32 V DC) and the output RESULT is set accordingly in the
function block INPUT when the final value (23 mA for > 40 ms) is exceeded. After about one
second the input automatically switches back to the current measuring range.

Input group I1 (IN4...IN7)
These inputs are a group of multifunction channels.
These inputs can be used as follows (each input separately configurable):
• binary input plus switching (BL) for positive sensor signal
• input for resistance measurement (e.g. temperature sensors or fuel sensors)
Possible operating modes inputs/outputs

Sensors with diagnostic capabilities to NAMUR can be evaluated.
