Communicate over Networks
Communicate Over a Universal Remote I/O Network
For the controller to control I/O over a universal remote I/O network,
you must perform this procedure.
1.
Configure the remote I/O adapter.
2.
Lay out the remote I/O network cable.
3.
Connect the remote I/O network cable.
4.
Configure the scanner channel.
As you design your remote I/O network, remember that:
•
all devices connected to a remote I/O network must
communicate using the same communication rate. These rates
are available for remote I/O:
–
57.6 Kbps
–
115.2 Kbps
–
230.4 Kbps
•
you must assign unique partial and full racks to each channel
used in remote I/O scanner mode.
Both channels of a 1756-DHRIO module cannot scan the same
partial or full rack address. Both module channels can
communicate to 00...37 octal or 40...77 octal, but each channel
can only communicate with one address at a time in whichever
of these two ranges it falls.
•
a channel can have up to 32 rack numbers with 32 physical
devices connected to it.
•
a channel can have a maximum of 16 block-transfer
connections.
