support for up to 32 I/O devices and update rates of 1 – 512ms. I/O device update
rates of 8ms and faster are possible with 16 or fewer devices. When there are
more than 16 devices configured, update rates of 16ms and higher are available.
• Supports two independents 10/100/1000 Ethernet LANs. As shown in Figure-1,
LAN1 attaches via the upper, dedicated RJ-45 connector. LAN2 attaches via the
lower pair of internally-switched RJ-45 connectors.
• 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.
