‑ IMMFP03 is station‑level multifunction processor, loads control strategy composed by function codes, completes continuous control, sequence logic, mathematical calculation, interlock protection.
‑ Interacts with local I/O modules on same rack via back‑plane bus, collects field process data and outputs control commands to I/O modules.
‑ Access INFI‑NET dual redundant ring network, exchange data with other MFP/BRC processors, operator stations, engineering stations. Supports hot‑standby redundant configuration, two IMMFP03 modules work as primary and backup in one rack.
‑ Supports online downloading configuration, partial online modification of function code parameters. Built‑in watchdog, when program runaway occurs, module will perform automatic reset.
‑ Installed on Symphony Harmony standard rack, can run independently to complete station control task.
Difference compared with IMMFP01：IMMFP03 optimizes memory capacity and network drive performance, supports richer function‑code library, better anti‑interference performance than early IMMFP01.
‑ Execute complete station‑level control strategy including PID regulation, logic interlock, arithmetic operation.
‑ Monitor own hardware status, network communication status, local I/O working status; fault information upload to operator station.
‑ Redundancy master‑backup switching function, when main module fault occurs, backup module automatically takes over control without stopping process.
‑ Back‑plane：Rack internal back‑plane module bus, connect local I/O modules.
‑ External interfaces：INFI‑NET ring network coaxial cable interface.
‑ Mounting：Plug‑in installation on Symphony Harmony 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.
- IMMFP03 multi‑function processor module（3BSE008514R1）
Complementary parts: Symphony Harmony rack, INFI‑NET coaxial cable, Harmony series I/O modules, redundant power supply, operator station, engineering station.
‑ Insert module into processor slot of Harmony rack, tighten front‑panel screws, guarantee reliable back‑plane contact.
‑ INFI‑NET ring network coaxial cable connection must follow specification, terminating resistance shall be configured correctly, avoid network ring break.
‑ For redundant configuration, primary and backup module need download identical function‑code configuration. Module replacement recommends power‑off operation; after replacement, download configuration and verify control logic and network communication.
‑ Pay attention to memory matching, old configuration project shall confirm compatibility before replacement.
