DIGITAL OUTPUTS
DigiRail Connect
has versions with transistor-sourcing digital output, identified as
K1 ... K8
, and with relay-type digital outputs, identified as
R1 ...
R4
, on its front panel.

Digital outputs
DigiRail Connect
has up to eight digital outputs (DOs), which obey commands received via digital communication. The registers of the
HR_DOx_VALUE
group are assigned to the digital outputs command. The writing of value
1
in these registers ENABLES the respective digital
output. Writing the value
0
, in turn, corresponds to DISABLES the respective digital output.
It is important to note that the ENABLE output status does not necessarily imply that the output is ON or activated.
A group of parameters determines the operation of the digital outputs. These parameters are presented by the
NXperience
configuration software
(see the
Configuration Software
chapter), which allows you to define the most suitable configuration for your needs.
The parameters required for configuring the digital outputs are described below.
5.6.1
ACTUATION MODE
The digital output has three actuation modes:
•
Logical Status
: The digital output reproduces the logical status of its respective status register of the
HR_DOx_VALUE
group.

"Logical Status" mode
•
Pulse
: With the status register receiving the
value
1
, the output will turn on for a specific time interval (set in the
Pulse Duration
parameter)
and then return to the OFF status.

"Pulse" mode
The ENABLE output status does not necessarily imply that the output is ON or activated.
•
Pulse Train
: With the status register receiving the value
1
, the output will create a defined number of pulses (set in the
Number of Pulses
parameter), with a defined duration (set in the
Pulse Duration
parameter) and in a defined period (set in the
Repetition Period
parameter). Af-
ter the pulse sequence, the digital output will return to the off status.
