 Hello.

Hi everyone,

I have a connection between two of PLCs by PUT/GET functions.

It is working fine, but I would like to make Profinet connection, that will not need add device to Network configuration in TIA Portal.

It is mean that I would like to make program, download to device and leave possibility that someone in future can connect with that device without make any changes in Network configuration in my device?

I have saw that, if device is not added in to my network configuration, then is not possible to read and write.

How to resolve that, it is possible?

Regards

It is possible to have the configuration of PUT / GET to have an "unspecified" partner. This partner does not have to be in the project. You only need the address.

On the 'slave' side the configuration is as you have now. That is to make the security setting to allow PUT / GET and the data source (DB) should not have an optimized structure.

The S7-300 and S7-400 can have a partner pull or push data to its DBs. The S7-1200 and S7-1500 requires open security and non-optimized DB structure. Any partner (master) can then link to it. Some 3rd party HMIs required this configuration.

Do realize that making PUT / GET possible, opens the system for external hacking. Then only the install environment secures the data.

#dP, thank you for your help,

I enabled PUT/GET in to device configuration, I disabled DB block as a "Optimized block access". Protection level in device configuration is set to "Full access" and all bytes are Accessible/Writable/Visible in HMI.

Communication is working only i if both fevices are in the same network in the same project.

If I created a new project, added unspecified device, recognize device and made new connection between this both devices in Network view, then I got Error from PUT/GET FB (Error status - 25 Communication has started. The job is being processed).

What I am doing wrong?

#dP, Thank you very much,

No it is work correctly :)
