XFL823 Binary Input Module
One instance of the L
ON
M
ARK
open-loop sensor object has
been assigned per input of the XFL823 Binary Input Module.
Each digital input object has its own configuration
properties, except for heartbeat configuration, which will be
shared among all objects.

Transmission
These variables are transmitted immediately when its value
has been changed by a higher rate than the configured
"send on delta" (in the case of the totalizer, “send on delta”
has a default value of 5 counts).
These variables are also transmitted as a heartbeat output
on a regular basis as dictated by the maximum send time
(nciSndHrtBt) (default = 0 = disabled) configuration variable.
Default Service Type
The default service type of these variables is
unacknowledged.
Fast Binary Input – nvoDiSwitch[ ]
This network variable output represents the logical state of a
fast binary input connected to the binary input terminals.

Default Value
The default value is set after power-up or reset and remains
until the module has measured a valid value.
Value = 0
State = -1
Totalizer Count – nvoDiCount[ ]
This network variable output indicates the total number of
transitions from 0 to 1 since the last reset due to power-up
or network reset.
Valid Range

Value
For totalizer counts

Table 69 Totalizer counts
Power-up/Reset
After power-up and reset, the value 0xFFFF = 65535 will be
sent to the network to indicate that previous count values
have been lost due to a reset.
