Hello 

  Many thanks for your support Mr.Ayman and other team whom gave me their experience

 

after i installed the Bus termination the Module is run properly and I could communicate with SIMATIC MANAGER with empty  MMC  , the bus termination is very important to RUN the ET200S .

still a small issue I couldn't connect module with original MMC which has the program of the machine  

Thanks & Regards 

Hello,

Great to know that part of problem have been solved.

 Do you have the original software on your PC? If yes download it to the empty MMC.

What's happen when you insert MMC into the CPU. Does the CPU enter stop mode? 

 HAPPY NEW YEAR GUYS!

Presently similar type of PLC in STOP mode problem I've been facing with IM151-8 PN/DP system. I've checked all the sorts of troubleshooting but still the problem is restated.

I've a Power Module, 04 nos of DI modules, 01 Counter module measuring distance, one AI module & 02 nos of DO modules. When I'm only configuring the HW keeping the CPU & DP master module then the PLC is coming to RUN mode. But whenever I'm connecting the PM module along with other IOM's the PLC is getting to STOP mode & never coming to RUN mode. In every attempt I've connected the Bus terminator but that's not solving the issue.

Another thing to mention that when I'm separately giving 24V DC supply to the CPU with DP master & separately to the PM along with IOM's all are showing normal RUN mode. But whenever I'm connecting the IOM with the CPU the controller is coming to STOP mode.

Now I've some queries:

01. How to resolve this issue?

02. Is it related to 5V DC bus voltage? If it so then how to check the 5V DC BUS VOLTAGE with multimeter?

03. If it's related to firmware related issue then how to check the Firmware? Is it possible without PG? If it's then how?

04. If it's Firmware issue then is it the Firmware of the CPU or the DP master module or all the sorts of modules? If related to all modules then where the firmware be available!

This HW is working in 04 panels but issue is with the 05th & 06th one.

Please reply soon because it's been faced for the last 08 days & we are also not getting proper guidance from other related sources also. Please refer the attachment for HW configuration related queries.

hi OMKRIS2017,

have you had a look online and in the diagnostic buffer?

Hello Guys!

The problem is solved. One pin in the DP switch is bend so the next power module is not getting the proper continuation of Bus Signal. After straightening the pin the issue is resolved.

Thank you guys for your support
