zenOn 5.50 SP6 driver

zenOn 5.50 SP6 driver

Dear community,

We have a old zenOn 5.50 project (HMI and PLC) that we like to rebuild.
How can we find out what PLC or Bus driver is needed and what the communication settings are?
We found following entry in ZENON.INI

[SYS_REMOTE]
CONFIG=DEVICE=TCP/IP;TIMEOUT=10;
INIT=1
BROWSE=1

Thank you
Volker
