Chapter 9
Reject Tracking
9–2
When you place the color CVIM system in the setup mode (or download a
configuration) in order to set reject tracking parameters, the system sets the
Module Busy status bit. Once you have set the appropriate reject tracking
parameters and returned the system to the run mode, they are available to
your PLC through the
Remote I/O connection on the color CVIM’s front
panel.
The PLC must initiate the transfer of these parameters when the Module
Busy bit (word 0, bit 3) turns off. These are the main steps that a PLC
program should perform in order to read tracking data:
1. Wait for Module Busy bit (word 0, bit 3) to change from 1 to 0.
2. Set bits 0 and 1 of output word 2.
3. Wait for bit 7 of input word 0 to turn on.
4. Read tracking parameters in input words 0 – 3.
5. Clear bit 1 of output word 2 (leave bit 0 set to post Part 1 inspection
results).
6. Wait for bit 7 of input word 0 to turn off.
7. Ready to begin inspections.
In order to accommodate the new commands and data pertaining to reject
tracking, the formats of the discrete input and output bits have been changed.
Specifically, Tables B.1 and B.3, in Appendix B of the Color CVIM
Communications Manual (Cat. No. 5370-ND010) have been changed.
Table 9.A on page 9–3 is an excerpt from the portion of Table B.3 on page
B–21 of Appendix B in the Color CVIM Communications Manual. The only
change to Table B.3 is in word 2, bits 0–3. The shaded area identifies the
affected word and bit numbers for the Remote I/O function. The arrow (
←
)
points to the new tracking usage item (in bold type).
When the bits are set as indicated, the PLC will request the color CVIM
system to send the data pertaining to the reject tracking parameters that you
set in the
Tracking menu.
Table 9.B on 9–4 is a modification of Table B.1 (page B–2) in Appendix B
of the Color CVIM Communications Manual. The modifications to Table B.1
are indicated by the shaded areas. Note that the tracking inputs are available
only through the Remote I/O port.
