The embedded Ethernet interface is supported by a dedicated microprocessor core. This
dedicated processing capability permits the CPU to support these two LANs with:
o up to 48 simultaneous SRTP Server connections;
o up to 16 simultaneous Modbus/TCP Server connections;
o 32 Clients are permitted; each may be SRTP or Modbus/TCP.
o OPC UA Server with support for up to 5 concurrent sessions with up to 10
concurrent variable subscriptions and up to 12,500 variables;
o up to 255 simultaneous Class 1 Ethernet Global Data (EGD) exchanges;
o two independent Redundant IP addresses, one for each of the embedded
Ethernet LANs.
