4.3.3 Tab: I/O Submodule DI16_01:Channels
The
I/O Submodule DI16_01:Channels
tab contains the following parameters and
statuses for each digital input.
Global variables can be assigned to the statuses and parameters with
->
and used in the
user program. The value without
->
must be directly entered.
Name Data type R/W Description
Channel no. --- R Channel number, defined by default
-> Channel Value
[BOOL] BOOL R Boolean value of the digital input LOW or HIGH.
-> Channel OK BOOL R TRUE: Faultless channel
The channel value is valid.
FALSE: Faulty channel
The input value is set to FALSE
Ton [µs] UDINT W Time on delay
The module only indicates a level change from LOW to
HIGH if the HIGH level is present for longer than the
configured time t
on
.
Important: The maximum reaction time T
R
(worst case) for
this channel is extended by the delay time, since a level
change is not detected until the delay time has expired.
Range of values: 0…(2
31
-1)
Default setting: 0
Toff [µs] UDINT W Time off delay
The module only indicates a level change from HIGH to
LOW if the LOW level is present for longer than the
configured time t
off.
Important: The maximum reaction time T
R
(worst case) for
this channel is extended by the delay time, since a level
change is not detected until the delay time has expired.
Range of values: 0…(2
31
-1)
Default setting: 0
Test Suppression [µs] UDINT W The module can filter out external test impulses (set from
HIGH to LOW for a short time) that last for the duration of
t
Pulse
< t
Suppression
.
The suppression time t
Suppression
can be configured by the
user.
The highest suppression time configured for a channel
applies to all channels on the module if the suppression
time set for the channels is greater than 0.
Note that the duration of the I/O cycle and thus that of the
CPU cycle is extended.
Range of values 0...500 µs
Default setting: 0 (deactivated for this channel)
Sup. used BOOL W Activated: The supply is used.
Deactivated: The supply is Not used.
Default setting: Activated
redund. BOOL W Requirement: The redundant module must be configured.
Acivated: Activate the channel redundancy for this
channel
Deactivated: Deactivate the channel redundancy for this
channel
Default setting: Deactivated
