Press<F7> (HELP) to change KF format (fixed point number) to KH format
(hexadecimal number) and vice versa.
3. Specify the status of the outputs that you want to force. Press <F6> (EN-
TER) to confirm the status.
Result: At the end of every cycle, COM ET 200 transfers output data to the
selected station. The software requests input data and (station) diagnostics
data. If problems occur, fault messages appear as text in the STATION
DIAGNOSTICS field.
The assignment of the function keys changes:
F2 F3 F4 F5 F6 F7 F8F1 F2 F3 F4 F5 F6 F7 F8F1
STOP EXIT
To freeze the screen, that is, to stop the update of the input fields, proceed as fol-
lows:
4. Press <F6> (STOP).
Now you can set the outputs again.
COM ET 200 displays the state of the inputs in the INPUTS
field in KM for-
mat for digital modules or in KH format for analog modules.
Inputs for a 464–8MA21 module (module ID 4AI, analog module):
Channel 4 3 2 1
KH = 0001 1E00 00A0 0250
In the OUTPUTS field, you can change the state of individual outputs (al-
ways shown as 0 when this screen appears). COM ET 200 displays the state
of the outputs in KM format for digital modules or in KH format for analog
modules.
Outputs for a 482–8MA12 module (module ID 027, digital module):
Bit 15 8 7 0
KM = 0110 0010 0001 0001
You can execute the FORCE function with the load circuit turned on or off as
follows:
