CHAPTER 3 CREATING PANEL APPLICATIONS
Link Type Description
Communication
service To allow other panels to communicate with the device that is directly connected to the target panel,
you need to add an appropriate communication service link to the application for that purpose. The
following table describes the available communication services.
Communication
Service Description
2-to-1 Server (COM) You need to specify the data link, i.e. the associated direct link,
for this communication service. This service allows two panels
to talk with one device and only one communication port is
required on that device.
2-to-1 Transparent
Server (COM) This communication service makes the target panel a gateway
for another computing device, such as a PC, another PM panel,
or a panel of other brand, to access the associated controller.
See the following diagrams to know the possible applications.
Any kinds of controller whose communication protocol is of the
request-reply type can be supported by this communication
service. Ask your local representative to check if your controller
is supported. Note that the communication parameters (baud
rate, number of data bits, number of stop bits, and type of parity
check) of the computing device and the communication
parameters of the 2-to-1 Transparent Server must be identical.
N-to-1 Master (COM) You need to specify the data link, i.e. the associated direct link,
for this communication service. This service allows up to 16
panels to talk with one device and only one communication port
is required on that device.
N-to-1 Master (Ethernet) You need to specify the data link, i.e. the associated direct link,
for this communication service. This service allows up to 16
panels to talk with one device and only one communication port
is required on that device.
