I have installed CX-One 4.29 on Windows10 Home and updated it after. No problems.

The project was working and being developed, but at some point... wtf?

2..4 are only suggestions. They were not deemed solutions of your problem. N-type CPU supports the ORG instruction.

1. What is your PLC CPU type?     Do you intend to search origin or set it by the program?    The ORG instruction is not supported in E-type CPU.    If supported in yours, something may be wrong with the origin search method or sensors    (do you have the home and home proximity sensors connected?). 2. A276 is 32-bit value, so use LMOV instruction. 3. You are using odd register numbers for 32-bit frequency value in the SPED instructions.    This is not forbidden, but it is a good practice to use even registers for 32-bit. 4. You may want to use PLS2 instruction, as it also features acceleration and deceleration,    while the SPED changes the frequency instantaneously.

I use Yaskawa Sigma-7 EtherCAT drives (equivalent of Omron R88M) with NX102. The MC_Reset instruction resets servo drive errors but not 9xx warnings. Once appeared, a warning stays on the drive display until the drive reboots (by control power cycled). Is there a way to reset the warnings programmatically?

I wonder why FB for such a small and simple task? As long as the program memory allows, I would simply rewrite it as many times as necessary, in the main program. FBs are data memory and scan time significant consumers.

Well, better than nothing. Thanks. Definitely, aliasing should be added to improvement requests.

That's very sad, as very often there is a dilemma between a variable individual meaningful name and being a part of array/structure/union.

This is not aliasing, neither its emulation even for the simplest example I gave.

I mean a rotary axis. Yes, from the program point of view it means cyclic position value. But what happens internally in the system for the axis position reading? Does the system create a true ring counter with position reset in every modulo cycle? If so, it will never overfill/rollover and the axis is truly infinite. Or the counter remains linear and only is recalculated into cyclic position? If so, it will overfill sooner or later, and this is exactly the moment I am aware of.

This is what I suspected. My concern is the rotary axis behavior at this moment, if it is moving forward in NoDirection mode.

Is a rotary axis truly infinite? Can it move infinitely in the same direction, without overfilling something eventually? I have not found any mentioning of rotary limits in the manuals, but still...

AutoHotkey does not work within Sysmac Studio window on my PC (Win 10). Specifically, automatic substitution of typed text. Does anybody have it working?

Is it possible?

Is it possible? For instance, I want a BOOL with own name to be aliased to a member of ARRAY OF BOOLS.
