Starting up the CS31 system after power ON, warm or cold start
(only 50 series)
Absolute identifier:
Symbolic identifier:
This system constant only takes effect if the basic unit is configured as the bus master.
Meaning of the value of the constants:
The user program is started.
The basic unit does not take any notice of whether the remote units are initialized and
adopted into the CS31 bus cycle: =0
The user program is not started until at least
n remote modules have been initialized and adopted into the CS31 bus cycle: =+n
Range of values:
Default value:
i.e. user programs are started immediately.
Changes to these system constants take effect:
on the next warm start or
on the next cold start
•
Size of the transmitting area of the slave basic unit
Absolute identifier:
Symbolic identifier:
Meaning of the value of the constants:
The slave basic unit can be used either in the digital area or word area at the CS31 system
bus. The digital values are transferred byte by byte. It is possible to set the number of bytes
(or words) which are to be sent from the slave basic unit to the master 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:
Changes to these system constants take effect:
on the next warm start or
on the next cold start
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.
