The Siemens 39ACM28AEN (16139-218/3) is a microprocessor-based Advanced Control Module Plus (ACM+) that serves as the central processing unit for Moore APACS+ distributed control systems. The Siemens 39ACM28AEN executes complex control logic and process algorithms, communicating with I/O modules via IOBUS and with other control or computer modules via MODULBUS. Powered by a 32-bit 68040 processor and equipped with 8 MB of battery-backed SRAM, the Siemens 39ACM28AEN stores and executes the operating system using FLASH EEPROM to prevent accidental modification. A redundant controller configuration can be established between two 39ACM28AEN modules using the onboard SCSI port. The Siemens 39ACM28AEN occupies a single slot in an APACS+ rack and requires the 16147-51 Transition Board for serial connectivity via two RS-232C ports and redundancy.
Central controller for APACS+ Distributed Control Systems (DCS) in chemical, petrochemical, and pharmaceutical plants
Process monitoring, discrete manufacturing, and batch control applications
Redundant control configurations for critical processes requiring high system availability
Migration and modernization of existing APACS+ systems to newer controller technologies
Data acquisition, alarm management, and system-level process coordination
Spare part replacement for legacy APACS+ installations still in operation
Oil & gas refineries, power generation facilities, and water/wastewater treatment plants
Microprocessor-based architecture with high-speed 32-bit 68040 CPU and integrated floating-point coprocessor
8 MB battery-backed SRAM for application configuration and runtime data with extended battery life
FLASH EEPROM for non-volatile operating system storage, preventing accidental modification and enhancing system security
Cold-start and warm-start values, real-time clock, and security features to protect configuration
IOBUS for communication with APACS+ I/O modules, MODULBUS for control/computer modules, and SCSI for redundant configuration
Redundancy connector and onboard SCSI bus controller for high-availability rack-to-rack redundant systems
Supports IEC 1131-3 programming: Function Block Diagrams, Ladder Logic, Sequential Function Charts, and Structured Text via 4-mation software
Three onboard LEDs for status indication: Module OK, Module Faulted, Module Unconfigured, Module Failed, Module Active, Module Inactive, Security Enabled/Disabled
Removable battery compartment with captive screw for convenient field replacement
Rack-mounted design fitting a single APACS+ backplane slot
Executes control strategies defined in 4-mation configuration software (up to 8 languages defined by the user)
Processes analog and digital inputs in real-time, executes PID loops and regulatory control algorithms (<1ms cycle time)
Communicates with I/O modules over the high-speed IOBUS to acquire field sensor data and write actuator commands
Manages inter-module communication with controllers, computers, and communication modules via MODULBUS
Provides redundancy functionality where a standby ACM+ monitors the active controller via SCSI, initiating an automatic switchover when a fault is detected
Drives discrete output modules based on logic execution and process conditions
Supports sequential function charts for batch and sequential control applications, plus function block and ladder logic
Stores configuration securely in battery-backed SRAM and non-volatile FLASH EEPROM to retain data across power cycles
Q1: What communication buses does the Siemens 39ACM28AEN support?
A1: The Siemens 39ACM28AEN supports IOBUS for communication with I/O modules, MODULBUS for control and computer modules, and a dedicated SCSI bus for establishing redundant controller configurations between two units.
Q2: Can the 39ACM28AEN be configured for redundant operation?
A2: Yes, the 39ACM28AEN includes a redundancy connector and onboard SCSI bus controller, permitting two ACM+ modules to operate in a redundant rack-to-rack configuration. Switchover occurs automatically upon fault detection or can be operator-initiated.
Q3: What programming languages are supported by the 39ACM28AEN?
A3: The 39ACM28AEN supports programming in four languages based on IEC 1131-3 using 4-mation configuration software: Function Block Diagrams (FBD), Ladder Logic (LD), Sequential Function Charts (SFC), and Structured Text (ST), which can be freely mixed within a single configuration.
Q4: Is the Siemens 39ACM28AEN still available for purchase?
A4: The 39ACM28AEN entered Product Cancellation effective October 1, 2011, and is no longer sold as a new product. It is available only as a repair part or spare for existing APACS+ installations until the end of lifecycle support in 2020.
Q5: What accessories are required for the 39ACM28AEN to operate?
A5: The 39ACM28AEN requires the 16147-51 Transition Board to access its two RS-232C serial ports and redundancy connector. A 3.6V lithium battery (P/N 14743-2) is also required to maintain the battery-backed SRAM configuration and real-time clock operation.
