Hi Jeffrey, Error ID AI-11343 -35 database file/path name too long What is your Concept install path? If it's default one, then check if following windows patches are installed KB840987 and KB841533 and deinstall they.

I see big cable on the left side of the power supply. May be it's only extended rack without plc and the plc is placed in main rack?

it looks like some technician have more experience as high paid system integrators ;)

vodoca, thanks for your respond

Hello Vodoca, Health Timeout setting in IO scanner affect only data, which you read from your slaves. So if communication with your slave going lost, then IO request will be not answered, the PLC wait 300ms (in our case) and repeat his request (3 times ?- I hope). After that if slave don't respond then the input data from slave will be replaced yb 0 in plc memory. The timeout value for digital outputs (+ENT11001) is between 300ms and 60s and must be configured via webpage of INT.

yes, to read firmware information from M1 the PLC will be stopped. Here is the firmware on my CCC:

never saw such ID. The hardware id of M1E should be 000A 0003. The current firmware version of 171CCC9x0xxx is 1.31. Are you using concept softwe? Then you will find also ExecLoader, which can read/write firmware to the M1E.

normally, the default value is "Fallback mode", so that after link down all outputs going to 0.

Hi vodoca, you can choose between fallback mode and hold last value and set timeout for some DDO via web browser. Just login with webbrowser to your NIP and set this settings.

Hello Vodoca, may be it's only firmware issue of M1E CCC, so that firmware update of CCC is needed. Cpuld you tell me which firmware has CCC9x0?

It's a good new one PLC without any known issues.

Just intall SESU Tool from UnityPro DVD and this tool checks for Updates for you.

Modsoft will be never for free, and you can't also purchaise it by schneider electric. The software is ablosete, so only service department by schneider can deliver any info about it. But google helps too :)

Hello ajb, are you sure about FC02? FC02 is reading of diagnostic register from slave. M340 and M580 are using same READ_VAR block to read the data from other devices.

Hello, I have never had such issue. Try to delete the module from the configuration, rebuild all application and add the module again - may it helps. Your firmware 3.12 is bad one (was blocked by Schneider), please update to 3.22 + CoPro 3.10. Could you please tell me serial number of your plc (via pm)? - may be you get trouble plc.

Hi vodoca, you understant this right. In the OFS configuration you choose your PRJ file from Concept, so that OFS knows the variables names and their addresses. >Does it mean I have to upload some initial RAM directly from PLC to Concept after downloading project changes from >Concept to PLC? Cannot find how to update OFS or where is the variables mapping stored. As I unterstand (I never used not allocated variables in Concept + OFS) just after some changes in Concept you save your Concept application as PRJ. During restart of OFS, the OFS reads PRJ+VAR file to get new information about new addresses. Also this steps are necessary to let it work: - In the file c:\windows\concept.ini change the parameter ExportVariables = 0 to 1 -cc2cat.exe / RegServer <- this step you need to do only 1 time after change the Concept version Thats all

If you are using not allocated variables, then after every changing of plc project you MUST reload the OFS server with new plc project, so that OFS knows new register-addresses

1) check ip adresses 2) check comm driver in VijeoDesigner

for PL7 Pro: STX for Modsoft: CFG for Concept: PRJ for Proworx: PWX no idea :( Which modicon plc do you have?

Just call Schneider Electric Support and you will get U8.0 XL trial as download link for free. Trial can't be registrated and works 60 days.

Hello sh3ro, 1) Modbus TCP/IP on your screenshot is the right protocoll. After that you need define the IP address of your plc and from HMI. 2) first time VJD download firmware and runtime to your HMI automatically

you have really strange question. File extension depends from used programming software. For PREMIUM PLC you need PL7Pro, which projects are saved as .stx or UnityPro, wit the file extension ZEF, XEF, STU, STA.

Hello Igor, just take OPC OFS Server from schneider electric and you will able in 5 min to read and write any registers via mb+ on your Quantum plc. You don't need any dll or something else. C++ make no sence.

It depends of exec on the plc - this plc can be programmed with UnityPro, Concept, Proworx, Modsoft

Never understand why someone need to write the digital inputs :(
