Channels
Channels are the media through which information about inputs/outputs of the MW (or broker) equipment
are sent or received.
These channels can be linked to physical entry points of the equipment like MODBUS queries according
to their compatibility with the channel.
The GRD/cLAN have 4 types of channels::
Digital inputs channels
Digital outputs channels
Analog inputs channels
Pulse inputs channels
The most common option is to link them in the following manner:
Channel Input/Output
I1..n DI1..n
O1..n DO1..n
AN1..n AI1..n
PI1..n DI1..n
Where:
Ix: is a digital input channel.
DIx: is a physical digital input.
Ox: is a digital output channel.
DOx: is a physical digital output.
ANx: is an analog input channel.
AIx: is a physical analog input.
PIx: is a pulse input channel
Beyond the most common way to link the channels like the previous example, it can be done in a
disordered manner or repeating them. This means that you could create a channel I5 linked with the DI13
input and a channel I6 that is also linked to the DI13 input.
On GRD/cLAN with serial port, I/O channels can be linked to Modbus queries if you use the embedded
Modbus master feature. If you do it, the queries will be shown on the "source" combo box (MB-DIx, MB-
DOx, MB-AIx or MB-PIx)
On GRD/cLAN with script programming support you can link script variables to any channel. The
channel will take variable value to send reports and when creating historical records. You can also
change the variable channel remotely if you link it with a digital output channel.
Adding Channels
To add channels in the “Configurator” you must enter the menu “Channels -> Type of desired channel”.
