Diagnostics
In the event of a diagnosis the module reports the following error causes (0
is set for bit 4 in the input byte):
Parameterization
Users can configure the following values using the programming system's
PLC configurator:
Value Description
0x14 Internal error
0x2B
Front element not plugged in
0x2C
Wrong front element plugged in
0x2D
Malfunctioning front element and/or plug-in connection
0x2E
Pushbutton fault
0x2F
Parameter fault
Function element
Description
Count direction If the module is not installed as described above, the counting direction will be inverted.
This problem can be fixed by changing the value for the module counting direction param-
eter.
Scroll direction
If the module is not installed as described above, the counting direction will be inverted.
This problem can be fixed by changing the value for the module counting direction param-
eter.
Quick scrolling
If the encoder is turned quickly for a continuous stretch of time, a "fast scroll" function will
be activated and the value will change ten times more quickly as the encoder continues
to be turned.
Updating interval
Updating interval for the numeric value from the module to the SmartWire-DT network
Scroll speed
If necessary, a prescaler can be used for particularly precise applications so that the scroll
speed will be reduced by having the value change only after the configured number of
rotary pulses is completed
Reset with pushbutton
Defines whether the pushbutton should also be used to reset the module value to the
reset value.
Upper and lower limit
Defines the upper and lower limits for counting. If these limits are reached, the counter
will not continue counting up/down. If the limits are enabled, the lower limit will always
be set as the starting value when the PLC is powered up or reset. If both values are set to
0, there will not be any limits. In this case, the lower limit will be set to 0 when the PLC
is powered up or reset.
Suppress 0x2E diagnostics
If the pushbutton is pressed for longer than four seconds, a "Pushbutton fault" (fault
number (0x2E)) diagnostic message normally occurs. Setting this parameter will suppress
this diagnostic alarm. (available from device version 02).
Reset value (in profile 2 only)
The reset value applied when a reset is carried out (with the confirmation button (if
enabled) or with the PLC).
