5 Configuration Tips

5.1 Targeting Points

The ENVOX workstation makes target information part of the source

point. This allows a point to be targeted to multiple devices without

entering the target data multiple times, but will still allow different target

parameters for different devices if desired.

This is accomplished through the use of Target Groups. A target group

is a list of target devices for a point, PROVUEs, UOCs, CHIPs and Trend

Units, which share the same target definition (reporting parameters, etc.).

This prevents the need for multiple entry of the same data if the target

parameters are the same for more than one device.

For example, consider a point that is targeted to 2 PROVUEs and a CHIP,

all with change-of-state reporting, 0.5% dead zone, and 3 a second

sample interval. These would all be targeted by creating one target

group with those parameters, plus all the other PROVUEĆspecific

parameters such as extended alarms, message suppress, etc. The

appropriate information for those three devices (the target group), which

are going to share target parameters, is entered on the Target Data

device list.

Now assume the same point is to be targeted to three other PROVUEs

with exception reporting, 0.125% dead zone, and a 1 second sample

interval. The targeting would be accomplished by creating another target

group with these parameters, and entering the list of device names.

The target parameters may be different for each device if desired. In a

worstĆcase scenario, where all devices that are to be targeted have

different target parameters, a different target group would be created for

each target device.

To target a point, select the Target!" menu option to access the Target

Data form. This form has fields for entering most of the target

parameters, plus a group field where a list of target devices can be

entered. The list of devices actually shows all the devices the point is

targeted to, with the devices in the current group being identified by the

word YES in the Current?" field.

To look at a different target group select the Next!" menu option. This

will display a different set of parameters, and a different list of devices will

be marked Current". To create a new target group, select New!" and

enter the new data.

Notice that not all of the PROVUE target parameters are on the Target

Data form(e.g. message suppress, unit point, etc). They are accessed
