Meaning of the value of the constants:
The slave basic unit can be used at the CS 31 system bus in either the digital area or the
word area. It is possible to set the number of bytes or words which are to be sent from the
master basic unit to the slave basic unit.
For use in the digital area:
-
Transmitting: 2...15 bytes
For use in the word area:
-
Transmitting: 1...8 words
Default value:
Range of values:
Note:
The default setting is
Digital area with:
-
transmit 4 bytes and
-
- receive 4 bytes.
This is defined by the default combination
KW 00,10 = KW 00,11 = 0.
The configured combination
KW 00,10 = KW 00,11 = 4
has the same result as the default combination.
The combination:
KW 00,10 = KW 00,11 = 100.
Is not allowed (It would mean transmit 0 words and receive 0 words)
Changing the system constants takes effect immediately.
