Addresses and Assignment of the Input Variables
Upon start the measurement program (1.bat) automatically assigns the input variables
(see menu
Specialist: System edit: Results or Specialist: System edit: Zero/Calib/Purge/
Other programs) to the board addresses (that are preset on the boards, ref. “ACQINIT”
→
p. 124, §9.2 ).
The assignment of the addresses of the digital board is invariable (
→
Table 2 ). For the analog
boards and subsequently for the heating controllers, the software first searches the
addresses of all physically existing boards and then assigns the channel numbers AO1,
AO2, etc. to the addresses one after the other. The channel number is thus
independent of
the plugged-in board type, its position and the individual board address!
Example:
“ AIx ” reads the xth analog input found .
In the following example “AI2” reads the analog input with the address 33.
The existing assignment is stored.
If, upon a new start, the measurement program finds that there is a change in the
addresses (e.g. because a board has been removed or a new one has been added),
then a message is generated (
→
p. 45, §5.3 ).
Example (continued) :
If, e.g. the analog input module with the address 32 had been removed:
Upon re-start of the measurement “AI2” will read again the 2nd analog input, but this is
now on the module with the address 34 (AI1 on address 33).

Usually the addresses mentioned above are pre-assigned in this way.

For the assignment of the board addresses of your system please refer to
your system documentation.

Please write down the board addresses, as a board can loose its address in
case of a possible fault.
You will find the pre-assigned addresses in your system documentation.
