Hi MSB,
Sorry, there is no easy way to do this.
If you need only a few boolean operands, maybe you can spend a few Input/Output connections.
Another possible solution would be to use a PLC with a Profibus-DP Master and two Easy204-DP, one per each easyNET cluster. But it's pretty expensive and a slow communication too, because of the EasyLink connection between the Easy204-DP and the easy800 or the MFD-Titan, which is a real bottleneck.
Best regards
Bernhard
