User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
7.8.2.
Logical channels - Hardware input mode
This mode allows the user to measure data from installed input modules which can be
displayed, and/or processed in any other logical channels (e.g. by a mathematical function or
virtual relay) or it can be the data source for controlling outputs.
The
Logical channels
parameters in the
Hardware inpu
t mode are:
–
Name
- it gives the name to the logical channel,
–
Unit
- for
Built-in
modules it will automatically use the default
Unit
, to change the
unit use the
Scaling
parameter in the
Processing
parameter block,
–
Mode=Hardware input
- in this parameter the user can select the source type of the
data for the logical channel,
–
Source
- in this parameter the user selects the source of the data from the hardware
input list for the logical channel (see below in this
Chapter
),
–
Configure source
button - after pressing this button the user can change the source
configuration, e.g. the range of the input value (see below in this
Chapter
), another
method to change the source configuration is to use the
Built-in inputs
menu
(see
Chapter 7.9. BUILT-IN INPUTS
–
Latch
parameter block - allows the user to set the
latch function
which will hold the
last value of a channel (discussed in
Chapter 7.8.1. Logical Channels - General
–
Processing
parameter block - is used for scaling and filtering data (discussed in
Chapter 7.8.1. Logical Channels - General settings
–
Displaying
parameter block - these parameters allow the user to select the format
and range of the data displayed on the screen (discussed in
Chapter 7.8.1. Logical
Source
parameter in
Hardware input
mode
After pressing the
Source
button a list of available hardware inputs appears. The
selected option will be the source of the data for this logical channel. A sample list of available
hardware inputs for a device with only one input module
