Thanks Jesper. I'll try it!

Hello All, I'm sure this will be simple for some of you, but I lack experience in this area. I have 8 CPU31x PLC's connected via MPI network. I want to create a DB to monitor a byte from each PLC from one "main" PLC. We are simply wanting to detect from one station, if there is a machine fault from any other station. Any ideas or advice would be appreciated!! Thanks! cartduty

Does anyone have any information in English about this software? I have visited the website scharnagl.com for info but it is all german. It didn't do me much good. We have a couple of machines that use this software for the HMI panel that is connected to a Siemens S7 CPU. We need to add some counters and buttons to the screen but I can't find anything in English. Thanks!!

It is a CPU318-2 With a 6ES7 951-1AK00-0AA0 1MB memory card. I'll try to change the memory card. Is the purpose of the memory card to store the program or is it just ram for calculations and such?

Does anyone have any ideas how to find what is causing these errors? Our PLC is losing the entire program at times. In the diagnostics buffer there were these errors Event #16 494E power failure followed by Event ID #16 4309 - Memory reset due to inconsistent data. This is followed by event #16 430E memory reset due to inconsistent data. Can anyone help? Thanks! PS - The battery is OK So I'm not sure why the entire program would be lost.

Hello All, Just replying about my problem. It turns out we can get by with just looking at four digits. There is a HEX command that will put four ascii characters into one register in a hex value. And inversely there is an ASCI command that will take a four digit hex value and put it into four seperate registers in ASCI command. Thanks for all the input!!

Hello all! I was wondering if anyone knows an easy way to concatenate 5 Data registers into 1 Register. I am reading in a barcode, as it is currently setup each character is put into a single data register. I would like to move them all into one register for easy comparison. Any ideas? Thanks in advance!!

Hello JesperMP, Thanks for the reply. However, it is the local variables in the FB's that I need restored. For example the variable name might be #out.conveyor_on but the new uploaded block shows #stat16.stat19 . This makes it very difficult to figure out what is what when there are 100+ variable names. I tried to copy and paste the old names into the uploaded block but I get an error saying there is a time stamp difference in the interface and the CPU may be put in stop mode. The associated DB also doesn't recognize the new names. I guess this should be a good lesson to always keep a current backup!! Thanks, Cartduty

Hello everyone! I recently had a laptop stolen and had to upload some blocks. We have the original program but it has changed throughout the years. The problem is that when uploading all the variable names in the interface block are lost. Is there any way to restore these? or retype them in where the PLC will accept? Thanks in advance, Cartduty

Hello everyone, I need some help in configuring ob13 to be called every 1 second. I tried using an example in the siemens manual but the cpu kept going into stop mode. The manual said to tranfer value to BS97. The cpu wouldn't allow this. So I put the following in ob21 & ob22. L kf+100 T SD97 BE I'm not sure the SD is right for the system data word. I know sometimes in the Siemens manual they use the German mnemonics instead of english. Any help appreciated!!

Since posting, the machine has started to function properly again. It had this error probably 5-6 times before running right again. I don't believe the PLC changed modes ( It stayed in run mode) because you just had to restart the machine. I am not sure about the error light. I'm sure the problem will return and i'll check that. I was mainly wondering if anyone had seen this particular error before.

Hello all, I have a C20H plc that is coming up with an system communications error that reads: "Unexecutable error clear, memory error, EEPROM write disabled, etc." Has anyone seen this? It always appears in the same position in the program, so I was hesitant to think it was a bad CPU. However, after I hooked up a laptop to monitor to see why the machine stops, I lose communication with the plc and the error pops up when the machine quits. I then have to reconnect to get back to monitoring mode. I thought maybe a memeory area could be damaged and it can't find a certain memory area. But that's just a thought! Any help or suggestions would be greatly appreciated.

Is there a command for a zone reset for an A2SH like ZRST for FX type plcs?

What does the special marker M9038 do in an A2SH type plc program?

Yes you were right. I was reading a DW to a HMI. I didn't even think to check the format in the HMI! DUH! Thanks Again!
