Input group ANALOG0...7
20856
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 ‰ von 32 V
• binary input plus switching (BL) for positive sensor signal (with/without diagnosis)
→ chapter
Possible operating modes inputs/outputs
(
→ page
187 )
All inputs show the same behaviour concerning function and diagnosis.
► Configuration of each input is made via the application program:
• configuration byte ANALOGxy_MODE
• FB
INPUT_ANALOG
(
→ page
123 ) > input MODE
If the analogue inputs are configured for current measurement, the device switches to the safe voltage
measurement range (0...32V DC) and the corresponding error bit in the flag byte ERROR_A_INx is set
when the final value (> 23 mA) is exceeded.
>
When the value is again below the limit value, the input automatically switches back to the current
measurement range.

Input group IN08...IN11 / FRQ00...FRQ03
19979
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 (with/without diagnosis)
• fast input for e.g. incremental encoders and frequency or interval measurement
→ chapter
Possible operating modes inputs/outputs
(

187 )
Sensors with diagnostic capabilities to NAMUR can be evaluated.
► Configuration of each input is made via the application program:
• configuration byte INxx_MODE
• Fast inputs with the following FBs:
FAST_COUNT (→ page 131 ) Counter block for fast input pulses
FREQUENCY (→ page 132 ) Measures the frequency of the signal arriving at the selected channel
INC_ENCODER (→ page 133 ) Up/down counter function for the evaluation of encoders
PERIOD (→ page 135 ) Measures the frequency and the cycle period (cycle time) in [µs] at the indicated channel
PERIOD_RATIO (→ page 137 ) Measures the frequency and the cycle period (cycle time) in [µs] during the indicated periods at
the indicated channel. In addition, the mark-to-space ratio is indicated in [‰].
PHASE (→ page 139 ) Reads a pair of channels with fast inputs and compares the phase position of the signals
