Discrete Bit Results

B–10

Note: When using the backplane, don’t write directly to word 2. Write to
word 1023. The CVIM will copy the data from word 1023 to word 2.

Note: When communicating with a device through the Pyramid Integrator
backplane, CVIM module results are posted in shared memory immediately
after processing. When communicating with a device through the other ports,
results are only available at the end of the inspection program.

Lock Request

0 = No Change
1 = Lock

Do not set bits 8 and 9 at the same time. If you set
both bits, the CVIM will be unlocked.

You must reset this bit to 0, then back to 1 to repeat
a lock request.
