I am very curios of why at all one would need to know that.

Other possible methods: - Use CNR/CNRX instruction. - Write desired time preset value to the timer present value, e.g. with MOV instruction.

Did you try increasing the responce timeout value in the Network Type in CX-Programmer?

Only decimal digits may be encoded in the bytes? The result value integer only? SIgned? Unsigned?

I already have the ST font adjusted, and wanted to do the same for LD. Maybe somewhere in the Windows Registry?

Is it possible to change the ladder font, and how? I am running Sysmac Studio 1.41 on Windows 10 and 7. Would like to change the font to narrower one, in order to fit more information in the screen. 

Will buy Beijer HT60t-Ne or Hitech PWS6620T-N operator panels, new or fully functional with no cosmetic flaws. Shipping to Canada will be required. These exact models. Not interested in other models.

Two projects. The same PC. Both projects created and edited on this PC, using the same version of Sysmac Studio. Able to attach element comments in one project and unable to attach to any element in another (the option is greyed out in the right-click menu). Element comments are enabled in the Sysmac Studio Option menu in both cases. Any ideas?

Thanks, this helped. It was set to 1.30 in the project. Another one is set 1.31.

Can you clarify, please, firmware version of what and where in the project?

As I said earlier, there is no difference in the PLC model (NX102 v1.41), Sysmac Studio version (also v1.41) and both projects are on the same PC. One project allows creating element comments, while another does not.

I wonder when/why would port(s) need reset?

Hello everybody I am using non-Omron (Yaskawa Sigma7) EtherCAT servo with absolute encoder on rotary axis. Can anybody explain the meaning of the setting on the picture? What values to be set here? Does it have to be the axis modulo in servo control pulses? What if the absolute encoder cycle is more than one cycle of the axis?    

Mind you, I created a small test program, and it was OK even in Smart Input Mode. Still, this mode is a disaster, and I never use it.

Try switching from Smart Input Mode to Classic Input Mode.

Plug to PLC USB port, autoconnect, and read its IP address in the port setup (CJ units) or D1200,1201 (CP1 communication board).

CP1L7Performance Specifications●CP1L CPU Unit (EM/EL Type) Memory backup Flash memory: User programs, parameters (such as the PLC Setup), comment data, and the entire DM Area can be saved to flash memory as initial values. Battery backup: The Holding Area, DM Area, and counter values (flags, PV) are backed up by a battery. Battery service life: Service life expectancy is 5 years at 25C, less at higher temperatures. (From 0.75 to 5 years depending on model, power supply rate, and ambient temperature.) According to the above, the counters are battery-retained. Do you have "Clear all memory on power up" or something similar activated in the PLC settings?

The precision of such registration will be limited to the value at the end of the last scan. Whatever count since- will be lost. I would do this in an interrupt.

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

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

So, here is a knife to the Beijers back- a simple and inexpensive programming cable for Mitsubishi FX series, to be used instead of SC-09. The cable is successfully used with FX0N, FX1N, FX1S, FX2N. EDIT: According to repeated complains this cable may not work with FX0, FX0S. The connectors on the diagram are 8-pin mini-DIN male on the PLC side and 9-pin sub-D female on the PC side. Take measures in order for the PLC pin 5 (+5V) not to be shorted with any other one in order to prevent the PLC or PC port damage. For AC powered PLC, the requirement to avoid phase conflict by powering PC from the same AC phase remains in power, exactly as for the SC-09 cable. The difference is that in a case of phase conflict at least cable is not damaged now.

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.
