EMS

Environmental Monitoring Systems (EMS) are essential in today’s pharmaceutical and healthcare industries to monitor environmental impacts on product, effluent pH and temperature, room pressures and any data that is deemed as product or plant critical. All our monitoring systems are 21CFR part 11 compliant and thus carry a full audit trail. In all cases the results of monitoring can be reviewed, analysed and backed up securely on a server for reference at a later date.

All our EMS panel designs are bespoke and are designed to meet our client’s specifications. Each panel has the facility, in the event of an alarm event, to send an email, SMS, activate a sounder beacon, and provide a volt free contact to integrate with existing site systems.

PLC

A Programmable Logic Controller (PLC) is a digital computer used for automation of electromechanical process, such as control of machinery on factory assembly lines, robots, water purification systems, door interlock systems, etc. Unlike general-purpose computers, the PLC is designed for multiple inputs and output (I/O) arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery backed up or non-volatile memory. A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operations may result.

HMI

The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of this interaction is effective operation and control of the machine on the user’s end, and feedback from the machine, which aids the operator in making operational decisions. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

A user interface is the system by which people (users) interact with a machine. The user interface includes hardware (physical) and software (logical) components. User interfaces exist for various systems, and provide a means of:

• Input, allowing the users to manipulate a system
• Output, allowing the system to indicate the effects of the users’ manipulation

Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy (self exploratory), efficient, and enjoyable (user friendly) to operate a machine in the way which produces the desired result. This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the human.

With the increased use of personal computers and the relative decline in societal awareness of heavy machinery, the term user interface is generally assumed to mean the graphical user interface, while industrial control panel and machinery control design discussions more commonly refer to human-machine interfaces.

Other terms for user interface include human–computer interface (HCI) and man–machine interface (MMI).

BEMS

A Building Management System (BMS) or Building Energy Management System (BEMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as BACnet, LonWorks, Modbus, and so on.

Our philosophy on the service we provide is based on over twenty years of experience. Our objectives are to install BEMS engineered to an energy efficient philosophy, on budget and on time.

We aim to:

• maximize the end users knowledge and confidence in their system
• Improve performance and efficiency during regular servicing & maintenance.

Our business is conducted by highly qualified and trained engineers who believe that communication, experience, knowledge and an approachable manner are key elements to higher standards of service. ACal can offer the following;-

• Design Assistance for new or existing systems.
• New build installations.
• Retro fit installations.
• Mechanical control panels & electrical installation.
• Problem solving solutions to existing BEMS system.
• Expert engineering for BMS Projects.
• Provide highly qualified engineers.
• Commission and Service systems to a high standard.
• Offer training and support.

We use a wide variety of products and technologies to implement effective solutions. We are committed to an open systems approach and utilise technologies such as LonWorks, BACnet, and Modbus to name a few.

 Trend

Anyone who is familiar with the BMS section will know or have heard of this manufacturer. Trend Controls has been the market leader for over 20 years. The business model in which Trend operates is popular with its systems integrators and industry specific consultants.

Many other control manufacturers look to Trend’s success and try to imitate their business strategy to improve turnover. We are now on the 4th generation of Trend controller and as a manufacturer, the product range covers virtually all aspects of the Irish markets demands.

We have found this product to be robust and reliable and in some cases out lasting the mechanical plant it controls. There are still controllers installed in the mid 1980’s residing in plant rooms working effectively. Trend has a vast partner network with one of the best technical support system of any manufacturer. This makes the product an instant hit with end users and consultants for many different control projects.
