Using The Totalizer Block

Building the Strategy

Adding Communications

1. Select the Library icon.

2. Select Communications from the library menu.

3. On the left side of the screen select the communications block required for the protocol being

used. Select either a Modbus or ICN block.

4. Place the block near the loop compound.

5. Open the block and set the slot location. For example: If you are using the on-board channel

of serial communications and are configuring the instrument from the front port the Modbus
block slot location will be “On-board”.

6. Compile the configuration and download it into the instrument.

Display Operation

Unless other changes were made in the strategy to cause a different behavior, the instrument will
come up in a manual mode with a local set-point. The output is displayed on the bottom line.
Pressing the scroll key once causes the set-point to be displayed on the bottom line. Pressing the
scroll key a second time causes the totalized value to be displayed on the bottom line and an up
arrow to be illuminated.

To enter the totalizer commands menu, press the up key while the totalized value is being
displayed on the bottom line. The action of “RESET” will appear on the bottom line and “ENT” will
flash next to the scroll key. Pressing the enter key (scroll key) causes the reset operation to be
enacted and transfers the operator to the totalizer display. If the enter key is not pressed the
action will time out, reset will not be enacted, and the operator will be prompted to exit the
totalizer commands menu.

This same operation applies to the STOP, RUN and HOLD commands. Each of these commands
are accessed after entering the totalizer commands menu and pressing the up key for each
command.

Pressing the enter key when “EXIT” is displayed on the bottom line causes the totalizer
commands menu to close returning the operator to the totalized value display.
