Log on and log off at the effective range

Introduction

An effective range is the range within which plant units, e.g. a machine, can be operated with

the enabling buttons of the HMI device. The prerequisite for this is that the operator must log

the HMI device on at the effective range.

Logging on at the effective range

If the operator enters an effective range with the HMI device the system shows that he can

log the HMI device on at the effective range via the "Effective range name" object.

To log on he touches the "Effective range name" object. Then he reads the effective range

ID in the plant and enters this ID in the ""Effective range logon" dialog box.

If the entered effective range ID agrees with the configured ID then the HMI device is logged

on.

When the HMI device is logged on the enabling buttons are active.

The system alerts the operator that the HMI device is logged on at the effective range in the

following manner:

● The LED "RNG" is illuminated.

● The "Effective range name" object is displayed in green.

● In the process cell the indicator for the effective range is active, e.g. a lamp.

When the HMI device is logged on at the effective range the following rules apply:

● The operator should not leave the effective range without logging off. Local rampdown

● No other HMI device can log on at this effective range.

Log off at the effective range

Before the operator exits the effective range at which the HMI device is logged on, he must

log off from the effective range. To log off he touches the "Effective range name" object and

edits the dialog box ""Effective range logoff".

When the HMI device is logged off the enabling buttons are no longer active. The

LED "RNG" is not illuminated.
