4.3.3 Programming under ORPHEE

Objects Designation
Input Input table with 8 words (each 16
tabulation - bit) as image of the inputs.
Words
The valve terminal occupies max.
64 bits of these.
Output Output table with 8 words (each 16
tabulation - bit) as image of the outputs.
Words
The valve terminal occupies max.
64 bits of these.
Input Error word. Shows an update error
tabulation - in the image of the inputs of a
Fault valve terminal.
A value other than zero indicates
that the values contained in the
input table are not valid (not
currentl).
*)
The operands of the input and output tables must be entered as a symbol, as
the format does not fit into the entry field of the screen mask. Assignment of
the symbols to the operands takes place in the Declaration Editor. Make sure
that you carry out this assignment without mistakes. You will then avoid
addressing errors.

4. Commissioning
With the variables defined in the configuration
screens for the valve terminals, the user
can access the inputs of the valve terminal and
set their outputs. The table below explains the
formats (mnemonic codes) of the objects avai-
lable for the valve terminal (device reference
FSD_C8).
All the error messages of the valve terminal can
trigger diagnostic processing %TD (like each
card in the rack and every other device
connected to the FIPIO-bus). More detailed
information can be found in the chapter "Diagno-
sis."
