High
Performance Controllers Overview
|
||||
 |
 |
|||
| The M4500 is a family of "fast" controllers designed for high performance machine applications which cannot be adequately handled by standard Programmable Logic Controllers (PLC). It provides a modular architecture which can be configured to handle critical control requirements for a wide variety of small to medium range high speed production applications. It's small form factor and rugged construction makes this system a cost effective and reliable solution for system upgrades as well as for OEMs on new and rebuilt equipment. | ||||

|

| Flexible
System Architecture
The
M4500 is a high performance Programmable
Logic Controller (PLC) with an optional built-in high performance
Programmable Limit Switch (PLS) with
advanced features that interfaces with a rugged machine mounted
resolver. Discrete DC input and output
boards, Analog I/O boards,
plus communication and motion
control boards allow the user to configure the system to the
I/O requirements of the machine. A display/keypad
is available to allow monitoring of production data as well as adjusting
set-up parameters. The specific control algorithm is accomplished
through the use of SYSdev, our unique
software programming package. This flexibility allows the user to
tailor a high performance critical function controller without having
to resort to a black box solution. |
||||
|
|
||||
| Wide
Range of Configurations
The M4500 can be configured for a specific application as either a PLC, PLS, PLC /PLS, or PLC/PLS/Motion Controller. The basic configuration consists of a PLC CPU mounted in either a 3, 4, 8, or 12 slot chassis together with an integrated or separate power supply. Using 32-point inputs and 16-point outputs, this allows local control of up to 320 I/O points. Using the optional communications board, up to 32 M4500 modules can be networked together. The
CPU contains built-in I/O including two digital interrupt
inputs, two analog inputs,
two analog outputs and
a parallel interface for the optional display/keypad. The PLS
section, which is fully integrated into the CPU, can be set
for either 8, 16, 32 or 64 timing channels with a scale factor up
to 4096. The motion control
features allow multiple axis servo motion control using either resolver
or encoder feedback. Versions for either door mounting or back-panel
mounting are available. |

| Efficient
CPU and Program Structure
The M4500 is a compiler based system utilizing advanced Intel MCS-96 microcontrollers. These CPUs provide fast logic solve times to provide sub-millisecond throughputs. SYSdev is an integrated software tool which is used to program the PLC, PLS, display/keypad, communication, and motion control processors. The SYSdev programming language allows PLC program files to be written in blocks of ladder, high-level (subset of "C"), and assembly. The
program structure of the
M4500 provides a user adjustable timed interrupt to implement critical
function control as well as user functions (subroutines) to implement
complex tasks . A library containing a wide variety of pre-written
user functions is available which enables enhanced features of the
M4500. Drivers are available to implement MODBUS and Allen-Bradley
DF1 communication protocols. Comprehensive fault
detection and hardware confidence test routines are embedded
as well. |
