5 Function module F23
Festo – P.BE-CPX-FB23-24-EN – 1305a – English 65
– The following table applies for the sequence of address assignment:
Address assignment (address type)
Area Addressing rules
1 Remote Ready (RR) Bit range – The last 16 inputs and outputs
(2 byte each) in the bit range (RX, RY) of
the last assigned station are
CC-Link-specifically reserved.
2 System diagnostic mode (status
bits and I/O diagnostic
interface)
1)
Word range – The system diagnosis occupies the first
16 inputs and outputs in the word range
(RWr, RWw) of station 1
1)
3 Digital I/O modules, e.g.:
–CPX-4DE
–CPX-8DE
–CPX-4DA
– CPX-8DE -8DA
or
Pneumatic interfaces, e.g.:
–CPX-VMPA-…
– CPX-VPMPA-FB-…
or
Pneumatic modules, e.g.:
–VMPA1S-D…
2)
–VMPA2S-D…
2)
Bit range – Addresses are assigned in the free bit
range (RX/RY) of stations 1 to 4.
– Arrangement from left to right
corresponding to the address range one
next to the other beyond the station
limits (ascending without gaps)
4 Analogue modules, e.g.:
– CPX-2A E-…
– CPX-2AA-…
Word range – Addresses are assigned in the w ord
range (RWr/RWw)
– The first module lies at a new station
address
– Addresses are assigned in the address
space after digital I/O modules and
pneumatic modules.
– Arrangement from left to right
corresponding to the address range one
next to the other
– Maximum 4 stations can be assigned
5 Technology modules e.g.:
–CPX-FEC
– CPX-CEC-…
– CPX-CTE L-…
– CPX-CMAX-C1-2
1) Only with ac tivated system diagnostics
2) Type of electronic module contained.
