Discrete Bit Results Bits
(Host Input & Output Bits)
This appendix lists the function of both the discrete bit inputs and outputs.
These bits can be accessed through the Remote I/O port and Pyramid
Integrator backplane. You cannot manipulate these bits through the RS–232
ports (A or B) but you can perform many of their functions.
With each inspection that the Color CVIM module performs, individual bits
are set. There are 256 bits that can be set as inputs to a host device. These
bits (part of the inspection results) indicate:
•
Configuration faults.
•
Module Busy flag.
•
Missed Trigger flags.
•
Results Valid flags.
•
Inspection Tool Pass/Fail/Warning flags
Note: If you are using the Remote I/O link, the bits for inspection tool
pass/warning/fail apply to either t the first part or the second part. You select
which part by setting bits 4 and 5 in word 3 of the discrete output bits.
Note: For your convenience, we have provided bit numbers for both a PLC
(octal) and Pyramid Integrator (decimal).
Note to PLC–2 Users: When you use any PLC–2 family processor with the
Color CVIM node adapter, you should understand the operation of the PLC
Block Transfer Done bits for Read and Write instructions. PLC–2 family
processors use the input image table for these bits all other PLCs can specify
integer files for this function. This means that a PLC–2 user must use proper
programming techniques to avoid confusion between the following bits:
•
Color CVIM discrete I/O input word 0, bit 6 (data valid first part) and bit
7 (data valid second part).
•
PLC–2 family input image table word 0, bit 6 (BTW done bit) and bit 7
(BTR done bit).
Table B.1 lists the discrete bit inputs.
