The MasterLogic PLC is a small and compact controller that
installs conveniently into a confined space and delivers power
and performance for a control application.
Modular and Scalable
MasterLogic PLCs are modular, scalable and rack-based. The
PLC can be either stand-alone or distributed with peer-to-peer
connections. The CPUs, power supplies and rack sizes are
available in various models to best fit a particular application.
Compact Size
Key Features
•Powerful and versatile processors – high speed i.e.42
nanosec/step, 7MB program (including system
memory), 4MB system memory, 2MB data memory,
16MB built-in flash memory for program and data
backup
•Full redundancy (CPU, power and network) – same
CPU can operate in both redundant & non-redundant
mode.
•Compact pocket size modules – rack room and
cabinet space saver
•IEC61131-3 standard programming – LD/ SFC/ ST/
IL language option
•A vast library of standard function blocks and support
for creating new or user-defined function blocks
•Over 50 types of I/O modules – digital/ analog
(isolated), HSC, RTD, TC, position/ motion control
•Open network protocols with field devices –
Profibus™ DP, DeviceNet™, MODBUS (Ethernet &
Serial)
•Open communication with external systems –
Ethernet, fiber-optic (100MBPS), serial RS232/RS422
•Peer-to-peer communications between PLCs –
Dedicated Ethernet 100 MBPS or Fiber-optic option
The module size is as small as 27x98x90 mm (pocket size). This
contributes to cost and floor space efficiency in today’s world
where floor space is a premium resource. Transportation is also
made much easier.
Speed and Power
A reliable processor makes it intrinsically powerful. All program
instructions are executed at a high speed of 42 ns/step, unique to
Honeywell. Even complex instructions are processed at this fast
speed.
A dedicated I/O bus controller supplements the main processor in
I/O refresh to achieve high speed scanning (e.g. estimated 15ms
for large PLC applications, say, 2500 I/Os and program size of
400 Kbytes).
•Smart I/O modules (DIN rail) on open protocols –
Profibus-DP, DeviceNet, MODBUS expanding I/O
capacity, remote I/O applications or as RTUs for
other manufacturers’ PLC
•Hot swapping, Interrupt programs, user-defined
Events (for SOE data in ms)
• Integration with Experion PKS, Experion HS,
Experion LS architecture (including system
diagnostics and clock synchronization) and SCADA
systems
•Self-diagnostics – network diagnostics, system logs,
Auto scan, monitoring system
•Engineering software – ease of configuration and
trouble-shooting
•Program simulator to test programs offline without
PLC/CPU

Open Network Standards
Industrial communication standards have continuously evolved
and so has MasterLogic PLC’s interface capability with them. In
addition to MODBUS (Ethernet and serial), MasterLogic supports
other protocols such as Profibus™ DP, DeviceNet™, OPC DA
server etc. Open standards network DeviceNet and Profibus
devices, such as smart actuators, sensors, intelligent drives and
transducers can be easily connected to MasterLogic. Its plug &
play features and open standards support make them easily
interoperable. On a physical level, Fast Ethernet, Fiber-Optic,
RS232/ 422/ 485 communication links are directly supported.

•MasterLogic allows for modularizing the entire program into
max. 256 easily managed sub-programs, executed once
every scan in the order. In addition, several interrupt driven
programs are supported:
Interrupt #program (max) Remarks

• Flash memory (16MB) for program and data retention
• Two built-in programming ports (USB@12MBPS and
RS232C)
• Built-in MODBUS slave RS232C communication port
• Real Time Clock (RTC)
• RUN/ STOP/ DEBUG mode of operation
• Configurable address range of two latch areas for data
retention (non-volatile memory)
•Self-diagnostics for system errors (memory, I/O, battery,
power, execution, delays)
•Direct I/O operation - IORF instruction for direct read/ write
of I/O modules for time-sensitive applications
Online Maintenance and Trouble-Shooting
•Hot-swapping of I/O modules through a software wizard or a
CPU dip switch
•Force I/O values (bit and word) for maintenance and trouble-
shooting
• Skip I/O of a selected I/O module or an entire I/O base
• User-defined Event Recording (SOE) – digital devices can
be configured for automatic event recording when falling,
rising or COS (change of state) with millisec, and timestamp
for SOE analysis
The PLC system alarm and event history is as follows:
Type Condition Size
Error Any error 2048 events
Mode RUN/STOP 1024 events
Power change Power ON/OFF 1024 events
System events Key system events 2048 events

Digital I/O Modules
MasterLogic has a wide range of digital I/O modules:
• 24V DC input modules (Sink source or source only type)
• AC input modules (110V or 220V AC)
• Relay, Triac, transistor ouput modules (sink or source)
troubleshooting, documentation and maintenance, etc.
• High resolution (16 bits)
• Digital value in 4 data formats
• Detection flags for input signal disconnect when analog input
range is 1 ~ 5V or 4 ~ 20 mA.
• LED status displays for RUN/ ERROR conditions
• Voltage/ Current switching option
• RTD (2-wire, 3-wire, 4-wire)
• Thermo-couple (K, J, B, T, E, R, S, N, C types)
Special Modules
• 2-channel high speed counter (voltage input or differential
voltage incremental encoder, preset function)
• Positioning modules
• Motion control module
If the field I/O signals are located too far away from the
MasterLogic CPU the same I/O modules can also be used as
remote I/O to reduce wiring costs and associated costs. In
addition, it also significantly increases the overall I/O capacity of
the MasterLogic PLC e.g. 23,808 to 128,000.
Project File
SoftMaster helps manage multiple PLCs through a single
window. One project file can include multiple PLCs from the site
as central storage of all PLC details.
MasterLogic Redundancy
For critical applications, eliminating all single points of failure in
the system architecture ensures high availability. Redundancy
features include:
• CPU redundancy— Seamless switchover to standby CPU
within 50ms when master fails without interrupting operations
• Power supply redundancy for both CPU and I/O racks
• Network redundancy — ring topology providing dual
communication paths to I/O racks
• High speed synchronization of program and data between
primary and backup CPU via dedicated fiber optic line
• Built-in twisted pair or fiber-optic networks for local (100m)
and remote I/O (2km) racks on ring topology
• Base type remote I/O functionality
• Base I/O capacity enhanced to 23,808 (372 slots in 31 bases)

Interface with Experion PKS, Experion HS, Experion LS
MasterLogic PLCs are tightly integrated with the Experion
architecture. They directly reside on the FTE or Ethernet network
of Experion PKS and the Ethernet network of Experion HS and
Experion LS, eliminating the need for any intermediate gateway
equipment.
• The interface supports configuring MasterLogic PLC
channels, controllers and points just like any other SCADA
interface
• For efficient communication optimization, the integration
supports both synchronous (timer based subscription of real
time data) and asynchronous (change of state, report by
