D
RAM initial address:
This relative address gives the position of the 2-byte data word for the
analog channel within the rho4.0 internal RAM area. The first RAM
initial address must be set equal to the initial address adjusted in P31.
If the initial address is set on 0, it follows the following RAM initial ad-
dresses.
RAM-BegAdr ANA-input 1:
0
RAM-BegAdr ANA-input 2:
2
RAM-BegAdr ANA-input 3:
4
RAM-BegAdr ANA-input 4:
6
If the initial address in P31 is set on 8, because for instance a B~IO
module has been connected with 4 analog ínputs, the RAM initial ad-
dresses in P407 must be changed into 8,10,12,14.
D
Format:
The data format is to be set to the 2 complement (positive and nega-
tive decimal numbers: Format = 0).
D
Nominal value:
The required nominal value to be doubled, since the internal number
representation of the SR-CAN module is connected to the factor 0.5.
The SR-CAN module only yields the value 500 for a nominal value of
1000 in the case of the applied maximum voltage of 10 volts. In com-
parison with this, a B~IO module would yield the value 1000. The de-
sired nominal value must be therefore multiplied with 2 to
compensate this behaviour.
Example
If the decimal value read is to be 1000 for a voltage of +10 volts, the
nominal value of the corresponding analog input is to be set to 2000.
