1 What is the MCT-CM?
The MCT system combines all of the features of typical loop controllers, video/chart recorders and data logging
system into a single/intuitive display device. Email (supporting SSL/TLS), SMS (text messaging), FTP,
FileWeb, DataWeb (file transfer protocols for automated data backup and web database interface) and remote
viewing/control (via Web server/VNC server) are standard with the MCT and can be accessed via LAN/WAN
using a PC, tablet or smart phone device.
Future Design Contro
ls’ “MCT” is offered in either a 4.3” or 7” color touch screen interface with standard “Smart
Device” user interface features for multi-loop OEM control applications (up to 10 loops). All loop configuration
and runtime user access are configurable at the
device with no PC software required. OEM’s have the ability
to configure runtime features (screen availability, menus, language, etc...) to easily customize the system for
their requirements. These configurations can be imported/exported to any other MCT device for setup within
minutes by the touch of a button.
In addition to a maximum of ten loops of control, the MCT-CM can also provide up to an additional 15 inputs for
process monitoring for a total of 25 process inputs. The system is provided with eight digital inputs and 8 digital
outputs standard. The MCT-CM can be expanded to a total of 16 digital inputs and 32 digital outputs. The
MCT-CM also provides the capability of accepting analog inputs for remote set point control and providing
analog outputs capable of retransmitting system variables (PV, SP or %Out) to other devices such as a chart
recorder. The 0-10Vdc or 4-20mA user selectable signals are provided through the addition of optional analog
expander cards.
Individual process controls, one for each loop in the system, provide reliable, consistent and accurate control
by distributing the process control requirements of the system among multiple processors. Each loop control
provides full auto tune functionality with high resolution, universal process inputs. When coupled with the built-
in ramping programmer, it allows for automatic, timed control of all processes and outputs of the system.
1.1 Features
The MCT digital inputs can be configured as alarm inputs with adjustable delay timers, as control inputs for
controlling automatic program operation or for direct control of the system’s digital outputs. The digital outputs
can be used as direct outputs for controlling external equipment related to the application through software
switches, called events, or be programmed to act as system alarm or status outputs. All outputs have adjustable
delay times for on, off and cycle times.
The MCT can be operated in single set point or automatic program control mode. Program entry is made easy
through the use of copy, paste and delete menu selections. Programs can be copied to the external USB
memory stick and then imported to another MCT controller eliminating the need to enter duplicate ramp/soak
programs into multiple systems. When running in program mode, the operator can place the system into hold
and change any control parameter without modifying the original program giving the operator maximum
flexibility over the controlled process.
Data logging can be enabled manually or automatically during program operation. Data backup is provided via
a USB memory stick for plug and play transfer of files to any PC and through the included FTP back-up utility.
Data file analysis tools make looking at historical data a simple task. Any control variable saved to the data file
can be plotted on the historical data chart for any time frame within the
data file’s total time range.
The built in Ethernet functionality includes a Web Server to provides access to all MCT data (view only), a VNC
interface for remote control and monitoring and an NTS clock, all available via a local Intranet connection (wired
or wireless), or the World Wide Web using a standard web browser.
System access is protected with a four-level security system (user rights based), including audit trail capability
that documents all user activity and ensures data integrity by digitally signing all data files and audit trails to
meet regulatory requirements.
