ProSoft PLX82-EIP-61850 Communication Gateway

Configured for bi-directional protocol conversion in EtherNet/IP and IEC 61850 power automation environments, the ProSoft PLX82-EIP-61850 (PLX82-EIP-61850 Standalone Protocol Gateway) provides direct physical/electrical execution. It bridges Rockwell Automation ControlLogix and CompactLogix programmable automation controllers with substation Intelligent Electronic Devices without requiring complex ladder logic programming. The dual Ethernet interface enforces complete IP subnet isolation between the plant control network and the electrical substation domain. Hardware Specifications Parameter Specification Model PLX82-EIP-61850 Brand ProSoft Technology Origin United States Weight 0.35 kg Dimensions 11.99 cm x 5.10 cm x 10.62 cm Operating Temp -25 deg C to 70 deg C Power Consumption 200 mA @ 24 VDC nominal (10 VDC to 36 VDC allowed, Max 450 mA @ 10 VDC) Network Interfaces 2 x 10/100 Mbps RJ45 ports (E1, E2) with auto-crossover Electrical Isolation 1500 V rms @ 50/60 Hz EtherNet/IP Capacity Up to 20 I/O connections (10,000 bytes Input / 9,920 bytes Output) IEC 61850 Capacity Up to 20 IED devices (Max 300 data attributes per device) Time Synchronization Integrated SNTP/NTP Client Mounting 35 mm DIN-rail Protocol Conversion Latencies and Network Isolation The PLX82-EIP-61850 processes MMS (Manufacturing Message Specification) telemetry under the IEC 61850-8-1 mapping profile and translates it into deterministic EtherNet/IP Class 1 I/O messaging. Internal processing latencies are minimized through an optimized memory buffer mapping architecture, which handles up to 10,000 bytes of input data and 9,920 bytes of output data. Dual independent physical network interfaces ensure deterministic performance by preventing broadcast storms and high-volume MMS reporting traffic on Subnet E2 from degrading Class 1 I/O implicit messaging latency on Subnet E1. Frequently Asked Questions Q: Does the module support hot-swapping or power removal under load on the DIN-rail? A: No, power must be isolated via the 24 VDC terminal block connector prior to removing the device from the DIN-rail. Disconnecting active power lines under load can cause voltage spikes or interrupt active MMS data client reporting streams. Q: How does the gateway maintain event timing accuracy across IEC 61850 IED devices? A: The gateway acts as an active SNTP/NTP client to synchronize its internal system clock. Time stamps received via Buffered Report Control Blocks (BRCB) and Unbuffered Report Control Blocks (URCB) are maintained within the gateway's internal dataset memory to preserve event sequence integrity for the upstream PAC. Q: What power bus limits apply when operating near the lower 10 VDC input threshold? A: While the unit accepts input voltages down to 10 VDC, current draw increases up to 450 mA at this voltage floor. External 24 VDC power supply sizing must account for initial inrush requirements and potential voltage drop across long field cable runs to maintain operational stability. Field Installation Guidelines DIN-Rail Mounting and Thermal Clearance: Install the gateway vertically on a standard 35 mm DIN-rail. Maintain a minimum clear space of 50 mm above and below the housing to allow natural convection cooling across the operating range of -25 deg C to 70 deg C. Shielding and Cable Routing: Use Category 5e (or higher) Shielded Twisted Pair (STP) cables for all RJ45 Ethernet connections. Ground the cable shields at both ends according to station ground standards to mitigate high-frequency EMI noise generated by nearby power switching gear. Power Terminal Wiring: Connect the 24 VDC power source using AWG 16 to AWG 20 copper wire. Ensure the power supply chassis ground terminal is securely connected to the panel earth ground bus bar with low impedance conductor routing (< 1 ohm).
