EtherNet/IP PLC、 Intelligent field devices (IFDs), frequency converters, MCCs, etc. support implicit (Class 1) and explicit (Class 3) communication and are compatible with Class 1/3 I/O adapters; Support Class 3 PCCC and UCMM (with Logix tags) message classes; Redundant communication requires special configuration (refer to the DeltaV System Planning Guide) with 256 devices and 32000 signals
IEC 61850 MMS motor protection relays, motor starters MCC、 Intelligent electronic devices (IEDs) such as switchgear use EIOC as MMS clients to read and write real-time signals; Not supporting historical data reading and GOOSE application. 256 devices, 32000 signals
OPC UA client OPC UA server (third-party device or system) follows OPC UA 1.03 standard, supports Data Access (DA) protocol, and only processes real-time data; Supports 128/256 bit encryption, message signing, and digital certificates (self signing/CA authentication). 64 servers and 30000 signals can be configured for online/offline browsing through NodeSet files
EtherNet/IP control tag integration ControlLogix, CompactLogix and other tag based PLCs access data through tag names based on EtherNet/IP Class 3 messages (without register mapping); Support string signal reading and array reading/writing (up to 64 elements per array, up to 100 arrays per EIOC); Only supports controller scope labels, does not support program labels. 256 devices, 2000 labels (10 signals per label, for a total of 20000 signals)
2. Parallel Redundancy Protocol (PRP)
Function: Ethernet redundancy protocol, primary and backup network ports communicate simultaneously, devices receive the same data through dual paths, zero switching time in case of failure, eliminating redundant network single point failures, suitable for high availability demand scenarios (such as IEC 61850 MMS electrical monitoring).
Usage conditions: The device must have native support for PRP; Non PRP devices need to be connected through RedBox to avoid abnormal diagnostic status; PRP is independent of application protocols and can be used in conjunction with all EIOC supported protocols without the need for additional licenses.
(3) Control module and functional block limitations
Control module capability: A single EIOC can run up to 2000 control modules, supporting basic functional blocks such as alarm detection, AI/AO/DI/DO tag I/O, logical operations, mathematical calculations, timers/counters, etc. The module execution rate can be selected from 100ms-60s.
Function block restrictions:
Supports a limited number of specific functional blocks: 256 DC/EDC/DCC (motor control), 26 PID (analog control), 16 SEQ (stepper), 16 STD (state transition diagram).
Unsupported functions: Batch control, SFC (Sequential Function Diagram), PLM (Process Logic Manager), equipment module, complex control requires PK controller or VIM2 card.
