Test programs using the EMULATOR
The EMULATOR allows you to check programs which have been written for the trip
amplifier 2/209. Once the program has been tested successfully it can be stored in the
trip amplifier (see <ALT><S>).
This tool replaces the hardware during program development. This effectively speeds
up the process of writing applications software. The program simulates the device 2/209
in all its functions. You can generate input signals on screen to check the relay and LED
action as well as that of the front display.
Call a program which you have written with the aid of the EDITOR. Run the program
through the COMPILER. Load this program into the EMULATOR by entering its
NAME.209 (NAME the program of your choice).
The EMULATOR offers:
•
single stepping (F7)
•
a monitor for variables (F8)
•
a monitor for constants (F9)
•
a monitor for the system (F10)
The basic EMULATOR input setting is for 0 % ... 100 % signals. However it is also
possible to apply hardware equivalents of 0 mA ... 20 mA, 0 V ...10 V, 0 V ... 5 V.
Reconfigure the EMULATOR dialling <F9>.
Solution
Check the cable.
Check that the correct COM link is being used typing
<ALT><C>. Check that the jumper MODE is in position 4–5.
Check that the jumper MODE in position 3–6.
Jumper KEY must be in position 1–8.
Use action 6 to load parameters from the trip amplifier with
<ALT><L>. Modify the program with <F5>. Use the
<TAB> key to move to the command which determines the
MIN or MAX-contact. Overwrite the line in question. e. g.
AHS MAX-contact which switches exactly on the set point.
Change to:
ALS MIN-contact which switches exactly on the set point.
End action by saving the program in the trip amplifier
following action 5 <ALT><S>.
The display can be altered in the same way, e. g. overwrite
H01 with L01.
