Trip Amplifier 2/209
Software description
After calibration has been completed the jumpers have to be changed back to the
operating mode. MODE = RUN (X5 3–6) and TEST jumper removed.
The calibration procedure eliminates tolerances of the precision resistors in the input
channels of the device. Conventional potentiometers have been replaced by non-
EN
volatile EEPROM memory.
4.3.9 Constants
P801 ... P820 contain constants K01 ... K20.
Constants are stored in EEPROM and can be altered ONLINE using the front push
buttons (see special commands). External access is often not permitted in safety
applications.
Data will be retained upon loss of power.
4.3.10 Variables
P901 ... P920 contain variables X01 ... X20.
Variables are stored in RAM and will be used for computed or interim values.
RAM contents will be lost upon loss of power.

Programming example

Install your PC software for the 2/209 trip amplifier (see section "How to install your
program").
Power the trip amplifier (24 V DC) and connect it to the personal computer (COM1 or
COM2). Analog inputs should be connected to signal sources.
Set the MODE jumper (X5) to programming X5.4 - X5.5 (see section "Functions –
General").
Start the PC program by entering START/1 (device connected at COM1 of the PC) or
enter START/2 (device connected at COM2). The screen will now show the main
MENU.
Open communication by entering keys <ALT><E> simultaneously. The selected serial
data link COM1 or COM2 should be echoed in the display window. Now enter the
command P700 followed by RETURN (ENTER).
The communication window will display as follows:
In case there is no reply from the device, please check your connection:
a) use the correct cable
b) use the correct serial data link COM1 or COM2
c) check the jumper positions
of the device (see above).
