2.3 Start-up behaviour of the controller
6827
15233
WARNING
Danger due to unintentional and dangerous start of machine or plant sections!
►When creating the program, the programmer must ensure that no unintentional and dangerous
start of machines or plant sections after a fault (e.g. e-stop) and the following fault elimination can
occur!
Realise restart inhibit!
►In case of an error, set the outputs concerned to FALSE in the program!
A restart can, for example, be caused by:
• voltage restoration after power failure
• reset after watchdog response because of too long a cycle time
• error elimination after an E-stop
To ensure a safe behaviour of the controller:
►monitor the voltage supply in the application program.
►In case of an error switch off all relevant outputs in the application program.
►Additionally monitor relay contacts which can cause hazardous movements in the application
program (feedback).
►If necessary, ensure that welded relay contacts in the application project cannot trigger or continue
hazardous movements.
►Additionally monitor relay contacts which can cause hazardous movements in the application
program (feedback).
►If necessary, ensure that welded relay contacts in the application project cannot trigger or continue
hazardous movements.

Analogue inputs
15444
The analogue inputs can be configured via the application program. The measuring range can be set
as follows:
• current input 0...20 mA
• voltage input 0...10 V
• voltage input 0...32 V
• resistance measurement 16...30 000 Ω(measurement to GND)
The voltage measurement can also be carried out ratiometrically (0...1000 ‰, adjustable via function
blocks). This means potentiometers or joysticks can be evaluated without additional reference voltage.
A fluctuation of the supply voltage has no influence on this measured value.
As an alternative, an analogue channel can also be evaluated binarily.
In case of ratiometric measurement the connected sensors should be supplied with VBBS of the
device. So, faulty measurements caused by offset voltage are avoided.

The binary input can be operated in following modes:
•binary input plus switching (BL) for positive sensor signal
• binary input minus switching (BH) for negative sensor signal
Depending on the device the binary inputs can configured differently. In addition to the protective
mechanisms against interference, the binary inputs are internally evaluated via an analogue stage.
This enables diagnosis of the input signals. But in the application software the switching signal is
directly available as bit information

• 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
→chapter Possible operating modes inputs/outputs (→page 207)
Sensors with diagnostic capabilities to NAMUR can be evaluated.
All inputs show the same behaviour concerning function and diagnosis.
Detailed description →chapter Address assignment inputs / outputs (→page 205)
Configuration of each input is made via the application program:
• FB INPUT (→page 173) > input MODE
• FBs FASTCOUNT (→page 169), INC_ENCODER (→page 171) or PERIOD (→page 175)
>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.

>
Self-protection of the output
15253
The hardware protects itself, irrespective of the operating mode of the output and of the fault
detection. In case of a too high thermal load (caused by short circuit or overload), the output driver
begins to clock.
The driver may be damaged in case of too long clocking of the output (several hours).
We therefore recommend:
that you operate device outputs with diagnostic capabilities in the following mode, since, in this case,
the software protects the drivers additionally by switching off:
• FB OUTPUT (→page 180) > input MODE = 16
This is also the default setting if only the flags in the control configuration are used.

Reaction according to the operating mode of the output
15252
In case of an overload or a short circuit, the behaviour of the output depends on its operating mode
(→FB OUTPUT (→page 180) > input MODE):
•MODE=2: binary output plus switched: no diagnosis and no protection
> the output continues to be operated.
•MODE=15: binary output plus switched with diagnosis
> error is detected and signalled on the output RESULT by the FB OUTPUT:
e.g.: RESULT = 128, 141, 142 or 145.
This depends on the type of output and the current or voltage at the output.
The programmer can react to the error in the program.
•MODE=16: binary output plus switched with diagnosis and protection
> error is detected and signalled on the output RESULT by the FB OUTPUT.
> The respective output is switched off.
> The logic state of the output remains unaffected by this!
>
Reaction when using PWM or CURRENT_CONTROL
15254
The situation is different when the FBs PWM or CURRENT_CONTROL are used:
There is no diagnosis. The →self-protection of the output becomes active.
►For outputs with current feedback:
Query the typical current for the output in the application program!
It is the responsibility of the programmer to react to the event.

Output group Q0 (OUT0, OUT1)
14583
These outputs are a group of multifunction channels.
These outputs provide several function options (each output separately configurable):
• binary output, plus switching (BH) with diagnostic function and protection
• analogue current-controlled output (PWMi)
• analogue output with Pulse Width Modulation (PWM)
→chapter Possible operating modes inputs/outputs (→page 207)
►Configuration of each output is made via the application program:
→FB OUTPUT (→page 180)> input MODE
PWM output: →FB PWM1000 (→page 182)
Current control and load current indication →FB CURRENT_CONTROL (→page 178)
►For the limit values please make sure to adhere to the data sheet!

Diagnosis: binary outputs (via current and voltage measuring)

The diagnostics of these outputs is made via internal current and voltage measurement in the output:

Diagnosis: overload

15249
Overload can only be detected on an output with current measurement.
Overload is defined as ...
"a nominal maximum current of 12.5 %" according to the data sheet.

Diagnosis: wire break (via current measurement)
19435
19400
Wire-break detection is done via the read back channel. When the output is switched (Qn=TRUE) wire
break is detected when no current flows on the resistor Ri (no voltage drops). Without wire break the
load current flows through the series resistor Ri generating a voltage drop which is evaluated via the
read back channel.

Diagnosis: wire break (via voltage measurement)
19436
19404
Wire-break detection is done via the read back channel. When the output is blocked (Qn=FALSE) wire
break is detected when the resistor Ru pulls the read back channel to HIGH potential (VBB). Without
the wire break the low-resistance load (RL < 10 kΩ) would force a LOW (logical 0).
