4.Establishing Communication with Controllers
4.1Introduction
Once you have connected the controllers and the computer to the network, installed the CN8-SW software, and changed the password on the MULTI login account, you are ready to establish communication between the CN8-SW computer and the controllers on the network.
You must do the following tasks.
∙Use the front panel user interface of each controller to assign each a unique address (between 1 and 254).
∙If the Omega Plus controllersÕ communication parameters have been
changed from the factory defaults, use the front panel of each controller to set the communication parameters at their default values as described in 4.2.
∙Use the Communications option on the CN8-SW Options menu to specify the COM port to be used by the Multi-Com software. If you choose not to use the automatic Òfind controllersÓ feature described in 4.4.2 to set up your
network, then you must also specify the baud rate to be used by the CN8- SW software.7 Configuration of communication parameters is described in 4.3.
∙Set the communication parameters of the controllers that support the
original Omega protocol to match the CN8-SW software as described in 4.2.
∙Make the CN8-SW system aware of all devices on the network as described in 4.4. This can be done using the automatic Òfind controllersÓ operation, in which the CN8-SW system seeks and finds Omega Plus controllers using the default baud rate of each controller and sets all the Omega Plus controllers to work at 9600 baud. Alternatively, you can add controllers to the network one at a time. If you use this manual method, then the software will poll at the baud rate specified in the CN8-SW Communications Setup window.
∙Save the set up as an .MCS files as described in 4.8.
7If you do use the Òfind controllersÓ function, the CN8-SW software will automatically use 9600 baud.
