The Meter As A Remote Display; The Meter As A Double Tasking Remote Meter - Omega DP41-B Series User Manual

7. Classes of Operation

7.3 THE METER AS A REMOTE DISPLAY

The meter has the capability to become a remote display. While in this mode, it can
accept any word with 1 to 6 letters (7 including one decimal point). Valid characters
are: numbers from 0-9, upper-case letters from A-Z, space, period, "/", "–", "+", "," and
"*". Upon receiving the proper command from the host controller, the meter will switch
to the REMOTE DISPLAY mode and display whatever has been transmitted to it.
The meter will continue to operate normally during this mode.
As an example, try to write "Hello my name is Bob" to the meter number 25 decimal
(19 hex) on the RS-485 network. Assume "*" is the meter's recognition character.
Transmit according to the following steps:
1) *19Y01HELLO<CR>
2) *19Y01MY<CR>
3) *19Y01NAME<CR>
4) *19Y01IS BOB<CR>
(You would want to generate a proper delay between each step.)
To go back to "RUN" mode, use the following command: *19D03<CR>
(See Section 8 for more information on commands).

7.4 THE METER AS A DOUBLE TASKING REMOTE METER

The Process, Strain Gauge, Temperature and Universal meters can be configured as a
double tasking remote indicator/controller. This is accomplished by transmitting any
value (In HEX format Only!) from "–99999 to 999999" (and any decimal point position
between 1 to 6) to the meter. The value transmitted will be the meter's Reading Value
which allows you to display any value desired and assign a setpoint as well as set up
the value of this setpoint. The meter can also be configured to output this value via the
optional analog output boards. The double tasking is accomplished during this
operation, the meter will continue to operate normally and the Filtered Value is the
value used for normal operation.
For comparing the transmitted value with any setpoint, the decimal point of the
value should be equal to the meter's decimal point position.
