Chapter 15
Connecting to a remote CX-Supervisor application
This chapter explains how to connect multiple CX-Supervisor applications together to form a
distributed solution. Point data from one application can be 'shared' directly with other CX-
Supervisor applications across the PC network. Depending on the requirements, there are many
reasons and topographies for interconnecting CX-Supervisor applications.
Two Tier, Client - Server or Master - Slave
One application is configured as a Server application or Master . The Server is often the main station,
and is permanently switched on, and often used locally for HMI for example but could have no
graphical element, which is termed a
Blind Server . It has direct access to the Devices or Device
network and is responsible for collecting the data from the devices.
Other applications may connect to the Server to read and even control values in the Server. These
applications are called Client applications or Slaves . Client s are often used remotely and therefore are
often configured 'display-only' applications, transferring the data from the Server using the corporate
PC network. The
Clients do not talk directly to the devices, and often only connect when required.
