3.5 Address assignment of the valves
3.5.1 MPA-S valve terminal with CPX terminal
Maximum 16 MPA pneumatic modules are permitted on
the MPA-S valve terminal with CPX terminal. The following
number of solenoid coils is therefore possible
(if only valves of the same size are used):
– MPA1: up to 128 solenoid coils
(maximum of 64 valve positions)
– MPA2: up to 64 solenoid coils
(maximum of 32 valve positions)
Note
Note with the addressing that an MPA2 pneumatic module
has only 4 addresses compared to an MPA1 pneumatic
module.
Assigning the addresses
– The assignment of the addresses is module-o rientated
– A pneumatic module always occupies
– MPA1: 8 addresses
– MPA2: 4 addresses
– Counting begins on the valve terminal from left to right
– Each valve position occupies 2 addresses, irrespective of
the valve or blanking plate fitted.
The following assignment applies:
– solenoid coil 14 occupies the lower-val ue address,
– solenoid coil 12 occupies the higher-value address.
