Sreekharan Posts: 3 Rating: (0)	Sir, We have a spare seimens S7-200 PLC and are trying to communicate, but showing communications time-out error, activity LED blinking in USB A2 adapter, but not getting connecting with port 0. The same laptop and settings were used to connect another similar S7-200 PLC in service. Please guide how to resolve this issue and get access to this PLC.

The manual can be downloaded from this link: https://support.industry.siemens.com/cs/us/en/view/68849363 and note the information on page 10. I hope this is helpful
	If you found this post helpul, I'd greatly appreciate your feedback with the rate function

Sreekharan Posts: 3 Rating: (0)	Thank you sir, this manual is already available with us, and we have already configured as per the same. The configured system was connected with a similar PLC in service. We are unable to connect with a spare PLC with us, where in activity LED is also blinking during the connection attempt. Please understand the same and provide solution if any.
