The Siemens 39ACM28ACN (16139‑106/2) is a microprocessor‑based Advanced Control Module (ACM) designed for the Siemens Moore APACS+ distributed control system. The Siemens 39ACM28ACN executes complex control strategies, acquiring field data via IOBUS from APACS+ I/O modules and communicating with controllers via MODULBUS and computer modules. Featuring a 32‑bit 68040 processor and battery‑backed SRAM, the Siemens 39ACM28ACN stores and runs the operating system from non‑volatile FLASH EEPROM for added security. This Siemens 39ACM28ACN also supports redundant configurations via its onboard SCSI port, ensuring high system availability in critical applications.
Central processor for Moore APACS+ Distributed Control Systems (DCS) in chemical, petrochemical, oil & gas, pharmaceutical, and power generation facilities
Process monitoring, batch control, and discrete manufacturing for continuous and batch processing industries
Integration with Moore 353/354N loop controllers and Proclia ipac controllers via Modbus, LIL (Local Instrument Link), or Ethernet (Modbus TCP)
Data acquisition, alarm management, and system‑level process coordination
Redundant control configurations for high‑availability process control
Legacy APACS+ system maintenance and spare part replacement for existing installations
Microprocessor‑based ACM with high‑speed 32‑bit 68040 CPU and integrated floating point coprocessor
Non‑volatile operating system storage in FLASH EEPROM (provides protection from accidental modification)
IOBUS for communication with APACS+ I/O modules, MODULBUS for control/computer modules, and SCSI for rack‑to‑rack redundancy
Support for standard Modbus protocol (RS‑232C), optional LIL (Local Instrument Link) board, and optional Ethernet board for Modbus TCP communications
Redundancy connector permits two ACM modules to operate in a redundant configuration via SCSI bus
Supports IEC 1131‑3 programming languages: Function Block Diagrams, Ladder Logic, Sequential Function Charts (SFC), and Structured Text
Three onboard LEDs for status diagnostics and local troubleshooting without an operator interface
Battery‑backed configuration memory with a 3.6V lithium battery (RAM retained when power is removed)
Security features to protect configuration (cold‑start and warm‑start values, real‑time clock)
Executes control strategies defined in 4‑mation configuration software using IEC 1131‑3 languages (function blocks, ladder logic, sequential function charts, and structured text)
Reads analog and digital inputs from APACS+ I/O modules via IOBUS, processes PID loops and control algorithms, and writes actuator commands to output modules
Communicates with other APACS+ controllers, computer modules, and communication modules via MODULBUS (IEEE 802.4 token‑passing bus)
Supports Modbus master function blocks for accessing data from Modbus slave devices; also supports LIL (Local Instrument Link) and Ethernet/Modbus TCP protocols with optional boards
Manages redundant configurations where one ACM actively controls, exchanging I/O and diagnostic data over the high‑speed SCSI bus, and automatically switches over upon fault detection or operator request
Provides two RS‑232C serial ports (via required 16147‑51 Transition Board) for serial communications with a personal computer, printer, or other Modbus devices
Stores operating system in FLASH EEPROM (instead of RAM) for non‑volatility and protection against accidental overwrites
Retains configuration in battery‑backed SRAM (RAM is accessible by all three bus masters)
Q1: Is the Siemens 39ACM28ACN compatible with my existing APACS+ system?
A1: Yes. The Siemens 39ACM28ACN is an Advanced Control Module (ACM) designed for the Moore APACS+ DCS, fully compatible with all APACS+ I/O modules, controller racks, and existing 4‑mation configuration software.
Q2: What is the memory size of the 39ACM28ACN?
A2: The 39ACM28ACN features battery‑backed SRAM (8 KB per vendor data; or 8 MB for the related 39ACM28AEN model) and 1 MB of FLASH EEPROM for non‑volatile operating system storage.
Q3: Can the 39ACM28ACN be used in a redundant configuration?
A3: Yes. The Siemens 39ACM28ACN includes a redundancy connector and SCSI bus interface, permitting two ACM modules to operate in a rack‑to‑rack redundant configuration with automatic switchover in the event of a fault.
Q4: What programming languages does the 39ACM28ACN support?
A4: The Siemens 39ACM28ACN supports all four IEC 1131‑3 programming languages: Function Block Diagrams, Ladder Logic, Sequential Function Charts (SFC), and Structured Text, which can be freely mixed within a single configuration using 4‑mation software.
Q5: What is the status of the Siemens 39ACM28ACN?
A5: The 39ACM28ACN is a legacy product for the discontinued APACS+ system (originally Moore Products). It is no longer in production but remains available as a spare or refurbished replacement part from industrial automation suppliers for existing installations.
