Chapter 4
Using the Remote I/O Link
4–6
When installed on a Remote I/O network, the Color CVIM module acts as a
slave device. Another device such as a PLC or computer will act as a host
device. This means that the Color CVIM module will not initiate the sending
of any data until a request is made by the host. To a host device, the Color
CVIM module will appear simultaneously as both a full I/O rack on the
network (256 input bits and 128 output bits) and as an intelligent module
with block transfer capability in group 0, slot 0 in the same rack. Refer to
Appendix B for a description of discrete bit data.
Note: If the Color CVIM module is the last node on a network, you must
terminate the communication line (refer to Figure 4.9 for an example).
Any Color CVIM communications port can be used by an external device to
read inspection result information. (Refer to Appendices B and C for more
information.) In addition, any device selected as a system (SYS) host can:
Change run–time display menus.
Enable/Disable local I/O board.
Force local I/O On or Off
A host device selected as a configuration host can also:
Upload or download Color CVIM module configurations for inspections.
Refer to Appendix D.
