Introduction

1.3Overview of Setup Tasks

The following tasks must be performed in this sequence to use the CN8-SW application successfully with an RS-485 network. The same basic process applies to using the CN8- SW application to communicate with a single controller over an

RS-232 link. In the case of RS-232 links, the ÒnetworkÓ consists of only the controller and the PC.

Change the password on the default account ÒMULTIÓ (not required, but

strongly recommended).

Set up operator accounts and assign passwords.

7

For controllers that support the original Omega Protocol, use each

instrumentÕs front panel to set the controller to use 8 data bits, no parity,

and controller

 

1 stop bit. Configure each controller to match the baud rate you plan to use

for the network. If you plan to use the automatic Òfind controllersÓ option

 

 

described in Step 11, set the Omega Protocol controllers to 9600 baud.

 

 

 

 

8

Use the front panel of all controllers (Omega Protocol and Omega Plus

4

 

Protocol) to assign a unique address (between 1 and 254) to each controller.

9

Configure the CN8-SW communication parameters and port selection. (The

4

 

CN8-SW communication settings will override, but not change, the operating

 

 

system settings for the selected port on your PC.)

 

 

 

 

10

Use the CN8-SW software to recognize each controller on the network

4

 

automatically. In the process, the CN8-SW software will set the baud rate in

 

 

all Omega Plus controllers to 9600. (By default, not all Omega controllers are

 

 

set to the same baud rate.)3

 

11

Name the controllers (optional, but recommended). By default, each

4

 

controllerÕs name will be its network address.

 

 

 

 

12

Save the .MCS (CN8-SW system) file so that the process of recognizing the

4

 

controllers does not have to be repeated if CN8-SW is restarted.

 

 

 

 

13

Set up local alarms (optional).

5

 

 

 

At this point you are ready to configure new controllers, or to begin monitoring process variables with the CN8-SW computer.

To change setpoints, see Section 6.

To change controller mode, including use of Autotune, see Section 7.

3You had to use the controller front panel in Step 8 to set the baud rate of controllers that support the original Omega Protocol, because that protocol supports reading the baud rate, but not changing it.
