Programmable Logic Software Support: Offering Reliable Solutions for Healthcare Facilities

A lot of mission-critical industries like pharmaceutical, chemical and nuclear plants, heavily rely on PLC or programmable logic controller for a more reliable, precise and automated control system for development, complex research and production procedure.

Right now, even leading healthcare companies are deploying programmable logic controller systems in their utility plant for remote monitoring, integration and automated control of their electrical-mechanical systems. Because of this, they achieve greater visibility, reliability and saved energy to meet their mission: high-quality operational efficiency and patient care.

Historically speaking, the healthcare industry has relied on using proprietary automation system to operate the heating, ventilation, and air conditioning system as well as the central plant equipment of any health care facility. As healthcare facilities grow exponentially complex, central utility plants also grow with them.

A programmable logic controller system refers to the network of PLCs that are installed on individual electrical-mechanical components that are integrated with acquisition system and supervisory data control, which is programmed to manage and acquire data and automatically control the entire system.

The programmable logic controller offers a lot of advantages over a building automation system that is usually used by hospital central plant installations. Among these advantages are reduced cost and an expandable system. You can visit sites like to know more about the services that each PLC company offer.

Robust and very reliable

Because of its origin in the control of the industrial process, programmable logic controller system components are intended to operate safely all the time in a very demanding environment, characterized by vibration and extreme temperatures.

The programmable logic controller system can also be bought with redundant hardware as well network options like dual processors, redundant supervisory control and data acquisition system and I/O or input/output redundancy for higher reliability and availability.

And because of its origins, which is in industrial process applications, programmable logic controller system is made with analogue sensors for the precise measurement of continuous values, like humidity, temperature, flow and pressure.

High-resolution analogue modules can deliver an increase in accuracy for info control and display. Although having an analogue sensor has always been a requirement in the industrial setting, they are not usually required in HVAC or heating, ventilation, and air conditioning applications.

In an industry where the mission-critical application is necessary like for example, a hospital, precise control and information is very important for medical research and most especially in-patient care. Precision is essential to optimize, measure and verify the efficiency of the energy.

A programmable logic controller system is also designed to authorize the separation of grounding system for instrumentation as well as electrical circuitry, if needed, to avert the electrical noise created by large engines in the central utility plant from influencing the precision of the operational measurements.

Even without the separate grounding systems, a programmable logic controller system has more point-to-point, built-in isolation for high noise immunity as well as increased precision. Because the programmable logic controller system is built on open standards, it is very flexible in several aspects.

It can receive multiple data from different manufacturers’ standalone hardware and platforms, including TCP/IP, Ethernet/IP, Ethernet, BACnet, Fieldbus, Modbus, ProfiBus and LonWorks while building automation system is limited to LonWorks and BACnet. Programmable logic controller system integrators can also harness a healthy mix of input/output module types like resistance temp detectors, thermocouples, analogue and digital input/output voltages, and pulse inputs, allowing direct wiring to a vast range of field devices.

The list of available modules often removes the need for conditioning devices and signal Isolators in the area, and it allows direct interface to power the equipment. All the module types can be inserted in the same input/output rack for flexibility when connecting to different devices in central plant applications.

Usually the building automation system utilizes 24VAC or 24VDC input/output and devices. A lot of companies’ service, supply and integrate a nonproprietary programmable logic controller system that a proprietary building automation system, opening up a lot of service providers bidding for the job.

In particular, business owners usually see significant savings on the annual service agreement. Because the programmable logic controller system is built on open software protocol, business owners are in control of future upgrades. Equipment, new methods, components and metering equipment are straightforward and simple to add in an existing programmable logic controller system.

Collecting and dispatching field data for monitoring

A programmable logic controller system will make it easier to collect and dispatch data if hospitals wish to engage in an independent energy oversight firm to identify optimization techniques and monitor the operations. The company’s integration platform allows an independent and continuous energy verification and monitoring agencies to provide optimization techniques and energy oversight to health care facilities’ staff and engineer.

The web-based monitoring structures can be an essential tool for analyzing large chiller plants as well as district cooling systems. The programmable logic controller system offers a networked solution that can collect and format information in real time, monitor equipment errors, monitor operations and deliver energy oversight using web-based alarms and alerts when the equipment is operating outside its optimal range. It makes the ROI or return on investment a competitive one with building automatic system companies. To know more about energy oversight, click here.

The information from different systems should be pulled together in platforms and should be pushed to the internet in specific time increments using a file transfer software. A programmable logic controller system is very is an ideal platform for different reasons.

In central utility facilities, not all systems are “flawless” in terms of communication protocols, so for example, if a 5- to 25-milliamp electrical signals are the only way to connect a separate device and different systems to enable the delivery of valuable information; programmable logic controller system can readily accept the form of communication, while building automatic system does not.

The supervisory control and data acquisition system used in programmable logic controller system can include data history capabilities to manage, gather, and store relevant information while building automatic system need to add proprietary software to get that capability. Not only that, programmable logic controller system usually transfers more information faster.
