‑ SPIET800 is dedicated Ethernet gateway module for Symphony Plus HR rack. Two independent Ethernet interfaces support network redundancy, when one network channel fails, the other channel automatically takes over communication without system interruption, improve system network reliability.
‑ Realize bidirectional data exchange: transmit rack I/O process value, alarm and event information to operator station; receive engineering configuration download, operator command from upper host, forward to SPBRC series controller.
‑ On‑board comprehensive self‑diagnosis function, detect module hardware failure, back‑plane bus abnormal, Ethernet link breakage; fault alarm information upload to DCS operator station. Support hot‑swap online replacement, reduce system maintenance downtime.
‑ Installed on Symphony Plus HR standard control rack, cannot work independently, must cooperate with SPBRC400/SPBRC410 bridge controller.
Difference compared with SPBRC410：SPBRC410 is main controller executing control logic; SPIET800 is dedicated communication gateway module, only responsible for protocol conversion and Ethernet data forwarding, does not run process control algorithm.
‑ Complete protocol conversion between Harmony Expander internal bus and industrial Ethernet, realize bidirectional data forwarding between controller and upper‑level host system.
‑ Monitor module hardware status, back‑plane bus communication status and dual‑Ethernet link health status, fault information upload to DCS system.
‑ No independent process control logic function, all control algorithm executed by SPBRC series bridge controller.
‑ Back‑plane：Rack internal Harmony Expander back‑plane bus for data communication and module power supply.
‑ External interfaces：Dual RJ45 Ethernet ports CH0, CH1, connect to DCS control network by shielded industrial Ethernet cable.
‑ Mounting：Plug‑in hot‑swap installation on Symphony Plus HR standard rack
‑ Operating Temperature：‑20 ℃ ~ +60 ℃
‑ Storage Temperature：‑40 ℃ ~ +85 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Pollution degree：Degree 2
‑ Protection Class：IP20, cabinet‑internal installation.
- SPIET800 ethernet transfer module（SPIET800）
Complementary parts: Symphony Plus HR control rack, SPBRC400/SPBRC410 bridge controller, Harmony Expander back‑plane bus, shielded industrial Ethernet cable, system power supply, operator & engineering workstation.
‑ Insert module into dedicated communication slot of HR rack, tighten front‑panel locking knobs to guarantee reliable back‑plane connector contact. This module supports hot‑swap replacement.
‑ Ethernet wiring adopt shielded twisted‑pair cable, separate layout from high‑voltage power cable to reduce electromagnetic interference; configure redundant network parameters according to project requirement.
‑ After module replacement, download corresponding communication configuration, verify back‑plane bus communication, dual‑Ethernet link status, data interaction between controller and operator station normal.
‑ Two Ethernet ports can be configured as redundant network, do not mix‑connect different network segments at will.
