Hello Mr.Yang, so far, Siemens rema

Hello Mr.Yang, so far, Siemens remains on the position that the setup for allowing GET and PUT communication inside the CPU of the PLC has to be downloaded directly with the HW configuration of the PLC.As internal rule I have always avoided this operation, even when possible, because if anything gets faulty on the communication channel, the lack of communication could stop the PLC.Anyway Siemens is confident that the possibility to prejudice the functioning of PLC is preserved by the fact that the new configuration is saved into the PLC memory only when the whole transmission is properly completed. So, next week, we may try to download the HW configuration one machine and then you can try the connection of your application.If your application is able to see the memory of the PLC, I you give the Sales Dept. all information for SW modifications required for your application. The machine needs to be switched ON but in emergency stop. It must be connected and enabled in your factory network for the remote connection.If anything in your network is changed, I will need to reconfigure the network and test it the day before the remote connection.After the download of the CPU, you will be required to synchronize few axes and the chain. This is normal. Do you think it would be possible carry out this test next week or later?Let me know.
