Festo CPX-FB36-EN en 1611a English
The function of DIL switch 2 is dependent on the set operat­
ing mode of the CPX terminal (è Tab. 1/1).
Diagnostics mode
(Remote I/O)
I/O diagnostics interface and
status bits switched off
I/O diagnostics interface is
switched on
Status bits switched on
Reserved
During subsequent activation of the diagnostics mode (status
bits or I/O diagnostics interface), the CPX-internal I/O illustra­
tion or address allocation can be shifted. The system control­
ler carries out this adjustment automatically. Manual manip­
ulation, e.g. a reconfiguration of the CPX terminal or manual
adaptation of the hardware and network configuration, are
not required.

munication of the bus node
with a control block
(e.g. B. CPX-FEC)
16 byte I/16 byte O for com­
munication of the bus node
with a control block
