Wow... really? Man, this is important, IMHO. I really like just about all of what OMRON creates, I have for years, but this PLC not having even simple embedded debugging capabilities really puts the NJ series (and others) at a disadvantage up against some of the competitors. On-board single stepping and breakpoints are critical to the development of large systems with a lot going on. If I had known this I probably would have specified a competitive PLC instead of the NJ501. But, I'm here now.
OK, I guess I need to figure out if I can build some of my own simple debugging primitives in ST. I hope you guys consider adding on-board debugging capabilities, soon! If you do, or if you already are, I would be happy to be a focused and communicative beta tester for you on that functionality.

I'm fairly new to Sysmac Studio, and the NJ series, but have done a lot of automation work for years.
It appears there are four ways to write/run code in the NJs, but there is only monitoring/debugging support for three of them:
- Ladder logic running on PLC: connection highlighting and variable watch/modify
- Ladder logic running in simulator: all the simulator single-step and other debugging tools
- ST running on simulator: all the simulator single-step and other debugging tools
- ST running on PLC: no way to debug or single-step?
Is my understanding here correct? I am just starting a large project that I was intending to do largely in ST, but if I can't single-step execution on the PLC, set breakpoints, etc., that's not going to work out very well for me and I guess I would have no choice at that point but to revert to ladder logic.
Thanks!

I've been through all the documentation I can on CX-Programmer, and for the life of me I can't find out what a small symbol means that has recently appeared on some of my instructions. It looks sort of like a capital 'T', I've attached a small screen capture that shows it. What is this thing? Thanks! -Hoobs WhatIsThis.bmp
NJ501: Details needed on the SktSetOption instruction
in NJ Series / Sysmac Studio
Posted
In doing a bunch of socket programming on the NJ501-1300, I have found what appears to possibly be an error/omission in all the manuals related to this controller. There is an instruction mentioned in numerous places, the "SktSetOption" instruction, but nowhere am I able to find details on it. What options can be manipulated? How is that done? Is there status information returned? While it is mentioned in several places, it is *not* in the NJ Instruction Reference manual, unless there has been a recent update to this manual that I have been unable to track down.
Does anybody know where the usage details for this instruction may be found?
Thanks!
