A picture can speak a thousand words. How about a diagram?

Make sure they know how to use generic modules too. The number of people I come across that can't add/or get ethernet devices up and running unless it has an add-on-profile.

How to restore a Library .SLR file to a Library Project
chelton replied to Chris Elston's topic in NJ Series / Sysmac Studio
Can't see anything in the revision history. Although can only see back as far as 1.28. https://automation.omron.com/en/ca/support/resources/software-revision-change-history/change-history-of-sysmac-studio -
How to restore a Library .SLR file to a Library Project
chelton replied to Chris Elston's topic in NJ Series / Sysmac Studio
The newer versions of studio don't even allow you to save the library as a .slr file. You can add a .slr file to a project however. Not sure when the .slr file support was dropped? Maybe try install an older version -
How big is your range of floating point numbers? Do they need to be added every scan? D100 - D110 is only 5 floating point registers. Easily done with 4 +F(454) floating point additions. You won't get any more efficient than that. However if you were adding 10 or more consecutive registers you may want to look at pointers/indirect addressing. Then you can choose if they are all added in 1 scan with a "FOR" loop or over consecutive scans.

Given that a D register is only 1 word / 2 bytes, you won't be able to move day/month/year into a single register. 1 nibble (4 bits) can only store the vales 0 - F

Upgrade a SLC 5/04 to ControlLogix
chelton replied to Riskinit's topic in Allen Bradley / Rockwell Automation
What information did you see on the terminal emulator? The module would be still operating in run mode and you would need to issue the break command (ctrl c) to stop the execution of the running program. Using the list command you only get the program listing running in RAM. Programs can also be stored on EEPROM. You can switch between using RAM & ROM commands. The modules are very hardy. I still have 1771-BAS in perfect working order. -
Under "Help > system defined variable reference" you will find this and many others.

I'd even consider using a redlion if it's for serial comms. Redlion's raw serial driver makes it easy to write your own ascii drivers. -
SYSMAC STUDIO - NX1P2 - Array copy help needed.
chelton replied to skyfox's topic in NJ Series / Sysmac Studio
Why do you need to copy the array? Can't you just set the address translation (AT) on the existing array to %D0. The array then should be accessible from %D00-%D59 -
Math Floating Point numbers without Registers
chelton replied to Abdul Wajid's topic in CX-Programmer
Floating point is entered directly by using the +/- character. See screenshot -

Indeed. I will add it to my list. Thanks Phil. -
PL7-3 Ethway in Virtual Machine
chelton replied to RiLo73's topic in Modicon / Telemecanique / Schneider Electric
@pturmel Would this work with a parallel port card? I have some old software that uses a sentinal hardware dongle that won't run anything more modern than WinXP. It's getting more and more difficult to find hardware that still has drivers for WinXP -

NXIP - Clear Range of memory that are not part of an array?
chelton replied to skyfox's topic in NJ Series / Sysmac Studio
When using AT to point at %d address it is essentially just a pointer. -
NXIP - Clear Range of memory that are not part of an array?
chelton replied to skyfox's topic in NJ Series / Sysmac Studio
Why not make it an array address? You can still have the other tags point to individual %d300-99 addresses
