SIMATIC WinCC Open Architecture Forum

Now I have three subsystem,
System A have a license of 15000 I/O and distributed manager,
System B have a license of 10000 I/O and distributed manager,
System C have a license of 10000 I/O and distributed manager,

System A want to acquire data from system B and system C by distributed manager.

system B only have 5000 I/O in use.
system C only have 7000 I/O in use.

Could system A acquire the data successfully?

Hello,

counting the I/O is only made on the local system by the drivers.
For acquiring data from a remote system using a distributed system you do not need additional I/Os at your license.
