Output State Control
On changing the Operating Mode of the PLC from RUN/MONITOR
→
PROGRAM, an I/O Bus Error or an Overflow/Underflow
Error, the Digital Outputs can be configured to:
•
Continue automatic updating Output States
•
Freeze Output States*
•
Predefine Output States*
Refer to 3-5-4
"Output Control Configuration"
Output Driver Configuration
The Output Driver of every Digital Output can be configured as:
•
NPN
•
PNP*
Refer to 3-5-4
"Output Control Configuration"
Reset Signals
Every Counter can be reset to zero by (a combination of) the following sources:
•
Software Counter Reset Bit
•
Digital Input*
•
Z-Input*
Refer to 3-6
Extra Functions
•
Programmable Output Pulse*:
To every Digital Output an ON-delay and/or a Pulse Duration [1, 9999 ms]
can be applied (refer to 3-7-1
•
Rate Measurement*: For every Counter the Pulse Rate can be measured by
defining a Time-Window [1, 9999 ms]. Up to a maximum of 64 Rate Values
are stored in the Rate History Log File. Rate Values from the Rate History
Log File can be read using the IORD-instruction. Additionally for every
Counter two Rate Ranges can be defined that control the Outputs according
to the measured Rate Value. Refer to
•
Hysteresis*: To prevent Outputs from being switched On and Off by very
small fluctuations in the Counter Value around Range Limits, for every
Counter an Hysteresis-value [1, 255] can be defined (the Unit must in Range
Mode). Refer to 3-7-3
Noise Filtering Counter Inputs
and Digital Inputs
To suppress noise on the signal lines of the Counter Inputs (A and B) and the
Digital Inputs (I0, I1, I2 and I3) a Noise Filter can be configured:
•
10 kHz*
•
50 kHz (default)
•
500 kHz*
For the Digital Inputs the 500 kHz filter can not be selected. The Z-Input
Signals of every Counter are filtered with a fixed Noise Filter of 1 kHz. Refer to
3-7-4
Initial Counter Value
•
The Initial Counter Value* is transferred to the Unit when the Unit is Powered
Up or Restarted. The Initial Counter Value is very useful to overcome
problems in case of power failure. Refer to 3-7-5
