The address of Color CVIM module shared memory is always SD13, with
the addressing as follows:
Color CVIM Thumbwheel No. SD13 Word/Bit No.
For example: Assume that the Color CVIM module has a thumbwheel
setting of #2. The data that you want to read is window 1
fault flag. Refer to Appendix B, the bit you want to read is
bit 01 of word 17. The PLC bit address would then be:
To access numerical values, you can use any PLC instruction which
manipulates file values. Values can be read individually or in groups. For
example, you can use the compute (CPT) function to move a single word
from the shared data (SD) file (resides in resource manager) to an integer file
on the local logic processor. Other PLC file instructions such as copy (FAL)
or compare (FSC) can also be used to manipulate shared data results.
Note: ACVIM family processor in the same rack must have different
thumbwheel settings.
When you transfer configuration data from the Color CVIM to a PLC–5/250
you use a message command and designate a long integer file as the
destination (internal table address). Long integer files contain 32 bit
elements. With this format, configuration block 1 would be arranged as
shown in Figure 6.1.
