Hidden code in Omron CPM1A

[kokko254]

I've got a problem with Omron Sysmac CPM1A-40CDR-D.
My machine controlled by cpm1a doesn't make all programmed moves like before. I suppose PLC is a cause. I thought that some instructions in code hangs or malfunction, so I have connected PLC to PC, imported instruction set code into Syswin 3.4 and analized. Seems like some code doesn't display. Those what is displayed is not complet. I was told that a software producer hides some code, provides himself monopoly for repair service So my question is:

How can I view hidden code?


Thank you in advance for any help.

If it can be revealed without authorization what would be the point of hiding it in the first place.
I would think (hope) that it cannot be done without assistance from the original author.

Sounds like job security to me.

First of all I would like to check is there hidden code or not, to make sure if my ladder is complete but partly hidden.

In syswin 3.4 there is no option like hide, secure or password protect. Which program should I try then?
