‑ On‑board Resources：Motorola MC68360 CPU 25MHz；1MB system Flash，512KB user application Flash；1MB RAM；hardware watchdog circuit；lithium battery for data retention and real‑time clock；hardware self‑diagnosis circuit
‑ Communication Interface：AF100 fieldbus interface；optical DDCS port；RS232 service debugging port；RS485 communication interface；internal back‑plane bus for S800 I/O modules
‑ Galvanic Isolation：fieldbus and serial channels adopt galvanic isolation, isolation rating 2500VAC
‑ Core Function：execute control logic, PID loop adjustment, interlock & sequence control, AF100 fieldbus master, DDCS communication, Modbus protocol support, hardware watchdog, comprehensive hardware self‑diagnosis
‑ Protection：surge‑suppression and ESD protection for communication ports, reverse‑polarity power‑supply protection
‑ Status LED Indicators：PWR power indicator, RUN running status, ERR fault alarm, AF100, DDCS, SER communication channel status LED, station address dial switch
‑ Weight：approx 1.0kg
‑ Installed on standard DIN‑rail, connects S800 series I/O modules through internal back‑plane bus. Single station runs one PM825 as main controller, this hardware version does not support CPU redundancy configuration.
‑ Executes Advant control software, completes continuous PID regulation, safety interlock protection, sequential logic control. AF100 fieldbus interface connects remote I/O and multi‑drop field stations. Optical DDCS interface realizes high‑speed data exchange between controllers. RS232 serial port is used for local program download, debugging and maintenance. RS485 supports Modbus RTU for third‑party device communication. On‑board lithium battery keeps real‑time clock and runtime process variables after power‑off. Independent hardware watchdog realizes automatic reset when program runs abnormally.
‑ Module self‑diagnosis continuously monitors 24V power supply, CPU operation, memory fault, bus and communication channel abnormality; fault codes and alarm messages are uploaded to Advant operator workstation.
‑ Cannot run independently; must cooperate with 24VDC power supply, S800 I/O modules and Advant engineering software. Compared with PM510/PM511 VME series, PM825 belongs to compact DIN‑rail AC80 controller for small‑and‑medium control tasks.
‑ Continuously monitors power supply, memory, back‑plane bus and each communication channel status. Hardware fault will light front‑panel ERR fault LED and report fault alarm code to operator station.
‑ No local historical‑data storage; runtime status and fault diagnosis information are read via Advant engineering configuration tool.
‑ CPU hardware failure will lead to control station out‑of‑service; no native redundancy function on this model.
‑ Back‑plane connector: connect S800 I/O unit back‑plane bus and 24VDC power supply.
‑ External interfaces：AF100 fieldbus port, optical DDCS port, RS232 service port, RS485 interface, station address dial switch.
‑ Mounting：DIN‑rail installation
‑ 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.
- PM825 processor module（3BSE010796R1）
Complementary parts: 24VDC power supply, S800 series I/O modules, AF100 fieldbus equipment, optical DDCS cable, Advant OCS engineering & monitoring software.
‑ Cut off power before inserting or replacing PM825 CPU module, hot‑swap function is not supported. Set station address via front‑panel dial switch according to project design. Use industrial shielded cables for serial and field‑bus wiring. Pay attention to lithium‑battery ageing, replace battery periodically to avoid loss of clock and retention data.
‑ For spare‑part replacement: verify full model PM825 and part‑number 3BSE010796R1; after hardware installation download firmware and user control program, verify logic operation, PID loop regulation and all communication channel data interaction. Mismatched hardware or incompatible firmware version will cause station startup failure.
‑ Module fault will result in control station stop; this hardware does not support main‑standby redundancy.
Power plant, paper‑making, chemical, water‑treatment old‑site Advant AC80 DCS control cabinets; small‑and‑medium process control station main controller; industrial spare‑part for Advant AC80 DCS CPU unit.
