SRTP Channel or Modbus TCP Client
(# simultaneous)
Ethernet Global Data (EGD)
Number of EGD Exchanges (max)
39
Selective Consumption of EGD
Remote Station Manager over UDP
Station Manager over Serial Comm Port
CPE400 Serial IO requires firmware version 9.40 or later.
Sixteen clients are permitted: each may be SRTP or Modbus/TCP.
EGD Class 1 only: supports up to 255 simultaneous Class 1 EGD exchanges.
Limit is per target, so all producers and consumers in the CPU system are counted towards this limit.
CPE400 and CPE330 (firmware version 8.90 or later) provide PROFINET support via an embedded PROFINET Controller: no external hardware is required. All other CPUs that support PROFINET require a
rack-mounted PROFINET Controller (IC695PNC001). CPE330 may also host IC695PNC001 modules in the CPU rack. Refer to the PACSystems RX3i PROFINET IO-Controller Manual, GFK-2571F or later.
For a discussion of OPC UA, refer to PACSystems RX3i TCP/IP Ethernet Communications User Manual, GFK-2224M Section 10.
Supports up to 5 concurrent sessions with up to 10 concurrent variable subscriptions and up to 12,500 Variables.
