 Hello Ziemens

What is the communication protocol you are using on the OP25. Serial , AS511 ,  Profibus ....

All new HMI's only support Profinet or Profibus.

There are some 3rd part devices that can connect to the AS511 port and then to a 'newer" HMI.

On the other hand you may also be able to find a OP25 (or similar) by searching online.

Regards / m.f.g

Communication is done using V24/TTY-interface IF1A PLC-interface.

Can we add a converter from TTY to Profibus (or to Profinet)?

Just do a search.
