We allow 64 incoming Masters and outgoing Slaves. This includes both network and serial devices
So as example - RSLinx to a Rockwell PLC:
A) Master incoming:
1) RSlinx via AB/Enet
2) UDP listener to 2001/2101 for serial port (TCP listeners don''''''''t count)
3) Serial "Master" to PLC since peer-to-peer - so 3 of 64 used
So 60 is usually the safe estimate of how many more Masters can connect or out-going Net Slaves we can connect to.
