4–1
Using the Remote I/O Link
In this chapter we provide:
•
Basic description of Remote I/O communications.
•
Connection diagrams.
•
Description of Color CVIM module setup requirements.
•
Three example PLC programs for accessing Color CVIM module data.
•
An example 6008–SI program.
As stated earlier, the Remote I/O port is located on the front of the Color
CVIM module and is labeled RIO. This port allows the Color CVIM module
to become a link in an Allen–Bradley Remote I/O network which can be up
to 10,000 feet long. Data on the network can be transmitted at baud rates as
high as 230K.

Use twin–axial cable (Catalog No. 1770–CD) to connect the Color CVIM
module to other devices. This cable connects to the Remote I/O port (labeled
RIO) and the next device on the network. Refer to Figures 4.1 through 4.8
for connection diagrams.
