Hello all,
I have a customer with an Omron CQM1 PLC. I had originally written the
program in the now dead Omron CPT programming software for this PLC.
However, the customer has recently purchased the new CX programming
software.
I imported the program and all the documentation successfully into the CX
programming package. BTW The program was well documented symbols,
descriptors, and rung comments. I then went on-site to make some program
changes. After getting on-site I wanted to make sure that the off-line copy
of the program that I had was accurate so I did an Upload of the program
from the PLC. Before the upload process began I was presented with a dialog
box stating that all my tag names and symbols would be overwritten I
acknowledged the dialog box and the upload completed. Upon completion all of
my rung comments disappeared. I still had all of my symbols and descriptors
but no rung comments.
I reopened the original program to get my rung comments back. However,
whenever I do an upload they are erased. Very Very VerRRRRRRYYYYYYY
frustrating!!
Needless to say I called Omron tech support about this problem. There
explanation is that this is normal behavior. An almost direct quote "Since
the rung comments are not stored in the PLC they should be erased when an
upload is performed."
I have never experienced this behavior with other versions of Omron
programming software LSS, CPT, or Syswin. I refuse to believe that this is
normal behavior. I tried to explain to the tech support rep, that this just
shouldn't happen, to no avail.
Anyone else had the same problem or any insight they can provide? Is anyone
from Omron lurking??
BTW I have been programming PLCs for 10 years. I know the difference between
uploading and downloading. I also know that all documentation is stored
off-line (i.e. not in the PLC memory). I also know that it is possible to
store in the CQM1 some documentation. I am not using that feature.
