Standard Screens
There are eleven standard screens available which require very little application programming. They are capable of
displaying a selection of up to eight process variables, together with their units of measure and tag description. Once a
screen format has been chosen, each input variable can be brought into view by pressing the up and down arrow keys.
These standard screens are ideal for many simple applications and can be implemented very quickly. However, where a
unique display format is required these can be built up using the commands that can be found later in this Programming
Guide.
For hosts that support the Modbus protocol, registers can be written to directly, without using any BEKA
protocol commands. Please see the “Serial Text Display – Modbus Interface Guide” for further information.
The screen format is selected by either using the local menu (as described in the Instruction Manual) or by using the
<SO
n
> Screen Option BEKA protocol command. One of eleven standard display formats can be selected as shown in
the following table:
