3.4 Arrangement of solenoids
The following drawing shows the arrangement of solenoids:
Station:
Slot for a monostable, bistable or center position valve. Depending on the valve
type, either
one or two
solenoids can be present.
Monostable
5/2-way valves have only
one solenoid
on the top position. (odd
numbers, solenoid
1, 3, 5,..
and so on).
3/2-way-, bistable and center position valves
have
two solenoid
s on top and
bottom position (solenoid 1+2, 3+4,... and so on).
Numbering of the solenoids starts top left and ends right bottom (see figure above).
The
„14“
on the label in the middle of the valve means, that air is flowing from
connection
1
to connection
4
when activated.
Group:
A group consists of
4 stations
(valves) or
8 solenoids
. The groups are numbered
from left to right. Each group is linked with one byte output data (8 bits) of the PLC,
i.e. o
utput byte 1
controls
group 1
,
output byte 2
controls
group 2
and so on.
HINT:
For valve types with
one
solenoid (odd numbers), the second solenoid is not present.
Therefore the output bits with straight numbers have no effect, they are "don't care".
