5.Configuring Local Alarms

5.1Introduction

The CN8-SW system can use the Omega Plus Protocol to read the alarm state of any controller that supports the protocol. Therefore, if an Omega Plus controllerÕs alarm parameters have been configured and the controller has detected an alarm condition, the A1 or A2 indicator on the controllerÕs Òfront panelÓ on the CN8-SW 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). Controller alarm parameter values can be changed using the CN8-SW software using the procedure described in Section 7.

As a bonus, the CN8-SW supports Òlocal alarmsÓ. These two process alarms can be configured in CN8-SW for each controller on the network, including controllers that do not provide an alarm function of their own, and controllers that support the original Omega Protocol.9 If a controllerÕs PV exceeds (high alarm) or falls below (low alarm) the configured local alarm limit, the alarm indicators on the main display will ÒlightÓ and the PV will change to red. Local alarms are configured using the procedure described below.

5.2Procedure

To configure local process alarms:

1.While logged in as MULTI (or another user with Controller Configuration privileges), select Controller Alarms. The Local Alarms window will open.

2.To enable local process alarm 1 (signaled using the controller imageÕs A1 indicator on the main display), click on the box to the left of Process High.

9Although some controllers that support the original Omega Protocol do provide parameters for configuration of controller alarms (such as the Series 16 controlers), their alarm status cannot be read using the original Omega protocol.
