Omega Engineering #M3350/0101 manual Viewing and Changing Controller Configuration Parameters

8.Viewing and Changing Controller Configuration Parameters

8.1Introduction

The CN8-SW system permits any operator with View/Change Parameter privileges to access parameter values stored in each controllerÕs memory.

The Omega Plus Protocol supports viewing and changing all parameter values over the network. These Omega Plus controller values are read and stored in non-volatile (permanent) memory.

The original Omega Protocol supports viewing the most important parameters and changing a sub-set of these parameters. You can specify whether you want to see and change the values in volatile (temporary) memory or in non-volatile (permanent) memory.

8.2Accessing Configuration Parameter Displays

To access the parameter displays:

1.Log in as MULTI (or another user with View/Change Parameter privileges).

2.Use one of the following two methods to access the displays:

∙select the controller by clicking on it in the main graphic display, then using Controller Parameters,

or

∙double-click on any controller in the main graphic display.

Either method will open the window showing the current value of the controllerÕs accessible parameters.

In the case of an Omega Plus-compliant controller, the window will contain a set of tabbed ÒlayersÓ. Click on a tab to select the group of parameters to be viewed.

8.3Using Configuration Parameter Displays

Be aware that not all displayed parameters apply to the selected device, or to the current configuration. In some cases the value of an unused parameter is gray, and no input is accepted. For example, on the 16th DIN Omega CN8500 Input tab shown earlier in this section, the Low Scale and High Scale parameters do not apply when a thermocouple input is used. Therefore, the Low Scale and High Scale values are gray. They do not apply to the current configuration and cannot be changed.
