Chapter 5 Programming

5.6.3.2 Setup a Point by Copying (Copy pt)

After selecting the point you wish to copy to, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Copy pt and
press the ENTER button. You will be prompted with "from pt? X". Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to
select the desired point number, 1 - 9 or A - F, from which to copy the point parameters, and then press the
ENTER button. You may continue programming to change the point parameters as needed.

5.6.3.3 Setup a Point by Restoring (Restore pt)

After selecting the point you wish to restore, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Restore pt
and press the ENTER button. You may continue programming to change the point parameters as needed.
NOTE: To restore a point, that point must have been previously programmed and still be in the system
memory. If the point was not previously programmed you will get a "PT NEVER SET" message.

5.6.3.4 Modify an Existing Point (Modify pt)

After selecting the point you wish to modify, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Modify pt and
press the ENTER button. You may continue programming to change the point parameters as needed.

5.6.3.5 Delete an Existing Point (Delete pt)

After selecting the point you wish to delete, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Delete pt and
press the ENTER button. You will be prompted with "confirm del?". Press the ENTER or YES button to
delete the point. Press the NO or EXIT button to cancel deleting the point.

5.6.4 Programming Point Types

There are various Point Types that can be selected from simple Linear to complex
equations. Once a point has been selected to Setup or Modify, the Point Type menu
will be displayed as shown in Figure 5-6. Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to
select the desired Point Type and then press the ENTER button. Some Point Types
will display a sub-menu with more specific options. Again, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN
(↓ ↓ ↓ ↓ ↓ ) button to select the specific Point Type and then press the ENTER button. The
Point Types available are:
Linear - Basic voltage and current input with linear scaling or dry contacts
Industrial Square Root (Ind sqrt) - Performs square root extraction on input
Log linear - Performs inverse logarithm on input
Rtd - Resistance Temperature Devices as defined
Calculated - Derived channels from user entered algorithms
Conditional - Boolean logic channels
External - Input channel via comm port

5.6.5 Programming Parameters

Depending on the Point Type selected, various programming parameters will be available in the Point Setup
Menu. Each of the possible parameters are described in the following sections.

5.6.5.1 Point tag

A Point tag is a name used to identify the point on the display or recorded file. It may be up to ten
characters long of which only eight will display on the screen. The Point tag appears on the bar graphs and
digital displays.
