Basic rule 1
With a mixed fitting, consideration is given to
the address assignment of the valves, digital I/O
modules and status bits.
1. Outputs:
The address assignment of the outputs
does not depend on the inputs.
1.1 Address assignment of valves:
• Addresses should be assigned in
ascending order without gaps.
• Counting should begin on the node
from left to right.
• S-type sub-base mod. always occupy 2 add.
• D-type sub-base mod. always occupy 4 add.
• ISO valve locations always occupy 2 add.
• Maximum 26 solenoid valve coils can
be add.
1.2 Round up to 4 bits: different cases:
a) If the number of valve addresses can
be divided by 4 without remainder,
continue with section 1.3.
b) If the number of valve addresses is not
divisible by 4 without remainder, it must
be rounded up to 4 bits because of the
4-bit orientated addressing.
The rounded up 2 bits in the address
range cannot be used.
1.3 Address assignment of the output modules:
The digital outputs are addressed after the
(rounded up 4-bit) addresses of the valves.
•
Addresses should be assigned in
ascending order without gaps.
•
Counting should begin on the node
from right to left.
•
Counting on the individual modules
is from top to bottom.
•
Digital output modules always occupy
4 addresses.
