XRIO
XRIO realizes the direct I/O level on the XCx. The RIO EC X2 bus
coupler and the expansion modules from the modular RIO system are
used (see also section Expansion Modules from the RIO System).
The bus coupler X2 IN is connected directly to X4 on the XCx
using a 9-pin subminiature-D connector cable.
Max. 4 bus couplers RIO EC X2 can be connected to the XCx.
The max cable length is 10 meters between two connection
points. Use shielded cables.
The RUN, ACCESS and ERROR LEDs indicate when the XCx
operating system is accessing the bus coupler.
So the RUN LED is red if the bus coupler is operating without XCx
or the PLC is in stop or startup status.
During normal operation with the XCx RUN and ACCESS are
green.
