Product description
In addition to the type of connection, you can also configure the following parameters for
an input/output:
Parameter
Description
Output (Out A,
Out B)
You can configure one of the following signals on the output:
Permanently 24 V, e.g. as voltage supply
Permanently 0 V (Out)
FPLC output signal
test signal for safety components fitted with contacts, e.g. an
emergency stop pushbutton
field-signal connections 7 and 8 only: monitoring a muting lamp
signal bit of an SDL-compatible component on the SDL connection
(bit set = 24 V)
Safety input
(In A, In B)
You can pass on the input signal as follows:
to the FPLC safety input
to the safety input of a device connected to the SDL connection
Input delay
[ms]
Delay (5–90 ms) between the detection of the signal change and the
effective evaluation of the input signal
Application: Several unintentional brief signal changes occur when
opening or closing a component fitted with contacts as the result of the
bouncing. In order for the bounce of the components fitted with con-
tacts not to influence the evaluation in the bus node, you must set the
input delay time longer than the bounce time of the components fitted
with contacts.
If you read in a contact without bounce time via the safety input, e.g.
the switching output (OSSD) of a light grid/light curtain, you must set
the input delay to
Inactive
in order to safeguard immediate signal
processing.
Check the response time of the protective device!
The configured input delays increase the response time of the protective device. You must
take these times into account when calculating the response time of the protective device
(see chapter 10.2 “Response time” on page 57).
Deactivate unused sections of the field-signal connections!
If you are not using an input of a field-signal connection, you must configure the safety
input of the corresponding channel with the aid of the CDS to
Off
.
If you are not using an output of a field-signal connection, you must configure the output
of the corresponding channel to
Static off
.
If a signal is still present on an input or output configured in this way, the bus node detects
this as an error status.
The bus node monitors the bounce time on each input and detects if the bounce time
exceeds the input delay time set.
