The results data for each inspection are stored in Random Access Memory
(RAM) and overwrite the results of the previous inspection. The data stored
in results blocks contain information regarding reference windows,
inspection gages, inspection windows, etc. For a complete description of the
results blocks, refer to Appendix C.
The user developed inspection parameters of the CVIM module are stored in
the CVIM module’s memory as configuration blocks. This area of memory
can be read or manipulated through the Remote I/O port, RS–232 ports (A &
B) or Pyramid Integrator backplane. Refer to Appendix D for a complete
description of the configuration blocks and their contents.
If you are not using the Pyramid Integrator backplane for communications,
you will have to physically link the CVIM module to the host device. If you
need to create a communications cable, refer to the chapter that describes the
communications port you are using.
Depending upon how you access the CVIM module results and configuration
memory, you will have to address the data differently. If you refer to
Appendix A, B, and C you will notice that separate columns are provided for
Backplane, RS–232, and Remote I/O communications:
Note: The RS–232 protocols (ASCII and DF1) do not access data using word and
bit addresses. Data is read/written in blocks. We have grouped the RS–232 and
Remote I/O ports together in Appendix B, C, and D (where appropriate) for your
convenience. You can ignore word and bit addresses if you are using the RS–232
ports (A & B).
