1. Introduction 1.1 Features 1.1.1 Transforms a PC into an Operator Station The CN8-SW software makes it easy for operators to use a personal computer to monitor networked Omega controllers. Linked to the controllers by an RS-485 network, the PC can be used to read process values, change setpoints and other parameters, change 1 controller mode, and monitor for alarms. CN8-SW is also ideal for quickly configuring a single controller in a lab or service department, using an RS-232 link.
CN8-SWÔ UserÕs Guide 1.1.2 Graphical Interface The CN8-SW software uses a graphical user interface and familiar point-and-click techniques. The main CN8-SW display shows PV and SP of every controller. The CN8SW system can be set up to show all controllers on the network on a single display, or only selected controllers. Any message that can be displayed on a controllerÕs front panel will also be shown on the CN8-SW display.
Introduction 1.1.3 Automated Ramp and Soak Cycles Use the CN8-SW Ramp and Soak function to configure any number of recipes consisting of any number of ramp and soak steps. These recipes are stored on the CN8-SW computer. Under the direction of CN8-SW, any controller on the network can execute your choice of recipe, even models that do not support configuration and execution of ramp and soak cycles using the controller front panel.
CN8-SWÔ UserÕs Guide 1.1.6 Local Alarms If a controller that supports the Omega Plus Protocol is in alarm, the A1 or A2 indicator on the controllerÕs Òfront panelÓ on the main display will appear to be lit (red), matching the behavior of the A1 and A2 indicators on the controller faceplate. The process value on the CN8-SW graphic display will also change color from magenta (normal) to red (alarm). As a bonus, the CN8-SW supports Òlocal alarmsÓ.
Introduction 1.3 Overview 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 CN8SW 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. St e p Ta sk Se c t io n in t h is M a n u a l 1 Connect the controllers to the network.

Establishing Communication with Controllers 4.1 Introduction 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.
CN8-SWÔ UserÕs Guide 4.2 Configuring Communication Parameters and Assigning Network Addresses in Controllers 4.2.
Establishing Communication with Controllers 4.2.2 Network Addresses Your goal is to assign each controller on the network a unique address between 1 and 254. This can be accomplished using the buttons and display on the front panel of the controller as described in the manual supplied with each controller. If you will have fewer than 254 controllers on the network and plan to use the CN8-SW function of automatically detecting devices on the network, use the lowest address numbers first.
CN8-SWÔ UserÕs Guide 4.3 Configuring Communication Parameters for CN8-SW System Your goal is to select the COM port to be used by the CN8-SW software. · If you do not plan to use the automatic Òfind controllersÓ option described in 4.4, then you can also specify a baud rate other than 9600 (the default) for the network. · If you do use the automatic Òfind controllersÓ feature, then the software will use 9600 baud, regardless of the baud rate specified using the Communications Setup window shown below.
Establishing Communication with Controllers 7. If necessary, change the Timeout from the default value. The Timeout is the number of milliseconds the CN8-SW system will wait to receive a reply from a controller before giving up and moving on to the next controller. 8. When the settings are correct, click on OK to save the settings and close the window.
CN8-SWÔ UserÕs Guide 4.4 Recognizing Controllers with the CN8-SW Software 4.4.1 Introduction Once you have assigned a unique network address to each controller, and set communication parameters in all controllers to their defaults, and set the CN8-SW to use the desired COM port, you are ready to enable the CN8-SW software to recognize the controllers.
Establishing Communication with Controllers · T h e s o ftw a r e p o l l s a d d r e s s e s 3 th r o u g h 2 5 4 a t 9 6 0 0 b a u d . · T h e n e tw o r k i s r e a d y t o o p e r a t e a t 9 6 0 0 b a u d . To use the automatic function: 1. Make sure all the controllers are powered up. 2. Use the front panel display and buttons on controllers that do not support the Omega Plus protocol to set their communication parameters to 9600 baud, 8 data bits, no parity, 1 stop bit.
CN8-SWÔ UserÕs Guide 8. Any message that can be displayed on a controllerÕs front panel will also be shown on the CN8-SW display. Operators can see at a glance if a controller is in standby or other special mode, and if the controller detects a problem such as an open sensor.
Establishing Communication with Controllers To return to the graphic view, select View | Graphic. When the instructions in this manual refer to the Òmain CN8-SW windowÓ, that means the graphic view.
CN8-SWÔ UserÕs Guide 4.4.3 Manually Using the Controller Menu If you want some operators to be able to see only some of the controllers on the network, you must use the manual process described here to add the controllers one operator will see, save the configuration to an .MCS file as described in 4.8, then start again, adding controllers to create a new different .MCS file for the use of a second operator.
Establishing Communication with Controllers 4.5 Deleting a Controller Any controller can be deleted from the CN8-SW setup, regardless of whether the controller was added using the automatic process described in 4.4.1 or the manual method described in 4.4.2. To delete a controller: 1. While you are logged in as MULTI (or another user with Controller Configuration Privileges) select the controller to be deleted by clicking on it (left button) on the graphic display.
CN8-SWÔ UserÕs Guide 4.6 Changing Baud Rate after Communication Has Been Established You can use the CN8-SW application to change the rate of all controllers that support the Omega Plus Protocol. As soon as you change the rate, you will lose communication with the controllers. Once all the controllers have been set to the same new rate, change the CN8-SW communication setting to match. Detailed instructions for changing the baud rate follow.
Establishing Communication with Controllers 4. To select another baud rate, use the dropdown list. 5. Click on OK. The value will be sent to the controller and the window will close. (Once the value is written to the controllerÕs non-volatile memory, communication with this controller is lost until the CN8-SW baud rate has been set to match.) 6. Repeat the process to assign the same new baud rate to every Omega Plus controller. 7.
CN8-SWÔ UserÕs Guide 4.7 Naming Controllers By default, the CN8-SW displays use a controllerÕs address as its name. However, you can assign a more meaningful name to each device. This can be done during the manual addition process described in 4.4.3. You can also assign a name (or change the assigned name) of any controller using the Controller | Configure menu function. A name may contain up to twenty letters, numbers, spaces, and special characters.
Establishing Communication with Controllers 4.11 Opening an Existing .MCS File To open a different .MCS file, use File | Open (or button on the toolbar). The operating system Open window will be displayed. Use it to select the .MCS file to open.
