The problem is, that 01000 does not switch off.

Hello, I have a very old omron SYSMAC C500 and there is some kind of problem. In lader diagram I can get til contact 01708, but it has no coil 01708. Is register 01708 some kind of special registers?

I have program only in papers, and dont know what happens realy in there. I only now noticed,(because its in Japanese) that Positioning module is showing COMM ERR, but Im not trying to connect with it. here is also the program part, where 01708 is used.

I have no SYSMAC LINK in my PLC system

Thank You for information

I have Mitsubishi Q02CPU PLC and I want to connect GTO970 to the PLC is it possible or GTO is to old for Q series? Also maybe someone knows which software I need for GTO970 programming, old dos type software or i can use GT2 or something like that?

Hi! I have CPU 400 series, but software is for 300 series STEP7 v5.3. is it possible that the software can't upload program to PLC because program are written with software for 400 series PLC? when I do Compile I have lot of errors

If I understand right, with GT Designer I cant programing old GOT only convert old program for new GOT. Then how call program whit I can program old GOT? I can buy new 15 panels for machines, so I need fix old

I have a software for GOT and cable. I already upload information from GOT to PC. For machine parameter change in GOT is set up password. Previous machine owners already throw away all information about passwords and other stuff. Now I need get password. Password is saved in GOT or in PLC?

I have a software for 870GOT. Can I use Mitsubishi PLC cable SC-09 for connecting made between GOT and PC?

Hi! On the PLC diagnostic I found error - > Fuse brake off. What does it means and where search problem?

But is it possible to connect new GOT generation to A series PLC?

Hi! Is it possible program A870GOT with GT Designer and can I use cable which I using to program A series PLC?

Hi! how to in GX Dev I can made a function, with give 10 times signal output with equal time interval? Or something like that?

Hi! I found Omron PLC CQM1H-CPU21, but I don't have a cable for him. In pictures cable looks like simple RS232 cable. PLC will work with simple RS232 cable?

So I can make my own with this schematic, or there also has some micro chips inside?

Problem solved X23 -| |-----[PLF M100] M100 -| |-----[sET M3] X20 -| |---[RST M3]

Hi! How to correct make a PLF function? I have sensor X23. If I understand write then begin is: -| |-----[PLF M3] and the next line must by something with SET, maybe someone can write the correct next line? Yes I have GX Dev and PLC ir from A series.

I have a conveyer, something are moving on them, when the part get past the sensor x23 it must stop, but the function don't work

hi all! Can i build my own cable for programming? I already buy cable, but i must wait a month to receive it, but i need already program PLC

I just want to known is there are difference between mitsubishi sc-09 convector for a series for something like this -> http://www.ebay.com/itm/New-Serial-Adapter-RS232-to-RS422-Data-Converter-Communication-adaptor-/251149255430?pt=BI_Control_Systems_PLCs&hash=item3a79a98306 ?

And pinout i must change or no?

can i any RS232 to RS422 coverter for programming?

I need an advice and schematic. I have A serries PLC. I found one schematic but i not shure did it works. Schematic is in an attachment CABLE.doc
