Q-Series - Operation Error 4100

7 posts in this topic

Hi guys.

I found error on PLC and from PLC diagnostic I found this Operation Error 4100 as per attach picture.

FYI, there is no SD card mount onto this PLC. I wonder what is ATA card.

This error wont affect the operation. Any advise on what to check?

An ATA card is a type of CF card which could be used with the first series of Q series CPU's. Now SD cards are used.

The error should only occur when File read or File write command is used. Isn't this instruction below the screencapture you send?

Hi Gambit,

Thanks for you reply.

What do you mean by File read/write? Is it the same as normal read/write like "MOV D1 D2" or is it read/write to/from ATA card?

Sorry I am not familiar with this instruction. 

Btw, why there is error when read/write command is used?

Thanks.

It's a command for reading values from a csv file from a CF flash ATA or SD card.

You only get the error if there is no SD card.

The instructions are FREAD & FWRITE (sp.fread sp.fwrite).

But if these instructions are not used in the program it is strange you are getting this error.

I believe there is no SD card attached.

Any advise on what should I check?

Some background,

1. There are around  7 PLC connected together through MelsecNET.

2. All PLC indicate this error. ERR LED lit up but not affecting sequence.

3. LED ERR will turn off after reset and come back on later, maybe after the instruction trigger.

4100 is a generic operation error... in your case it has nothing to do with a memory card or a network...

Look at the FIRST line of the error message... THE INSTRUCTION CANNOT PROCESS THE CONTAINED DATA.  When it gives you a program name and step number, it's a program error.

The instruction it is highlighting is having an error with the input data... so what is put in via K4X460 does not work in the DBIN instruction... check the status of your inputs starting at X460 and see what it is trying to do.  And look at the help for DBIN to see what about it can cause the 4100 error.
