FX5U Label name incorrect

[pacak]

Hi there!

I'm new to GX Works3 so please bear with me.
So far I've created a new project with an FX5U PLC and tried to add some global labels with input devices.
At the third label (E-STOP_2_OK) when I press the Check button on the Global Label page, the background of the label becomes red.
If I recompile all, I get the following error message:
Label name is incorrect. 'E-STOP_2_OK' is reserved word. Please modify the label name.

Any ideas?

OK. So it looks like GX Works 3 does not like dash in a label.

Attachment is from the GX Works3 Operating Manual, Appendix 2, reserved words, symbols which cannot be used.
I do not see any dash in that list.

Also looks like a label has to be a single word: bla bla not ok, bla_bla is. Could not find this mentioned in the above manual or the FX5 Programming manual (Program Design).

Mitsubushi, this does not begin well!

hello,


you're probably using an outdated manual

Hi!
Thanks a lot!
I thought about it but could not find the issue date.
It is in the Revision section. Now I have a doc from April 2021: SH(NA)-081215ENG-AD

E- is actually floating point subtraction so that is why it's reserved, spaces are also not allowed.
