4.2.7 Special Operations
Display menu:
The DSP command has to be placed at the beginning of a program. DISPLAY
commands must be in sequence. Other commands follow.
The order in which display commands are used determines the sequence of parameters
displayed when pushing the STEP key on the device front.
Example
• input 1, trip point 1,
input 2, trip point 2
or
• input 1, input 2,
trip point 1, trip point 2
Front push buttons will operate ONLINE, i. e. trip points continue to be monitored while
the buttons are pushed. The program will read the push buttons once every cycle. It may
therefore be necessary to press a push buttons several times before the unit responds.
Push buttons can be used to change constants. This is used to set trip points. Press SET
to initiate changes (two keys simultaneously to protect against unintentional changes).
The STATUS line will flash.
Use UP/DOWN ">" "<" push buttons to adjust the value.
Store the result in non-volatile EEPROM by pressing STEP key. Prior to storing the value
in EEPROM you can restore the previous setting by pressing the UP/DOWN buttons
simultaneously "ESC". The keys terminate the programming mode (display stops
flashing). If keys are not pressed for 30 seconds the SET mode is terminated
automatically.
Action:
Display operand op1 in mode op2.
The lower line will carry the alpha character a and the numerals nn . DSP commands
have to be placed at the beginning of a program. The front push buttons are used to step
DSP commands or change constants.
In the EDITOR operands op3 ... op5 are grouped together.
Example
DSP,X01,Z00, E01 (see example programs in DEMO directory)
Call DSP,op1,op2,op3,op4
DSP = display
op1 = variable or constant upper line
op2 = mode: (0 = float, 1 ... 4 = (n
o
- 1)decimals)
op3 = ASCII: (A ... Z e. g. "#E")
op4 = num. (0 ... 9 e. g. "#1") lower line
op5 = num. (0 ... 9 e. g. "#0")
