Control system monitors entire facility
GB Innomech decided to integrate as many functions as possible into one central control system that could constantly optimise the entire building for energy performance.
A CC-Link control network is at the heart of one of the most innovative ecological buildings in the country GB Innomech, based near Ely in Cambridgeshire, is an automation solutions company specialising in solving difficult manufacturing problems

If the active master PLC processor fails for any reason, the standby PLC processor takes control immediately with a "bumpless" changeover.
Explaining worldwide fieldbus differences
All fieldbus protocols share the same, really rather short, history, but that does not mean they are anything like equal.
GB Innomech's Keith Reeds said "In our every day work we are constantly assessing and specifying industrial control equipment, so we had some idea of how much the environmental controls should cost and what sort of performance we could expect".
"When the proposed system fell short of our expectations we did some calculations of our own and decided that industrial grade automation equipment would give far better control and performance at much lower cost".
The system that GB Innomech designed is based on a PLC (programmable logic controller), an HMI (human machine interface or interactive graphic panel) and distributed networked local control nodes.
The company to integrate as many functions as possible into one central control system that could constantly optimise the entire building for energy performance.
A total of 150 digital and 50 analogue inputs monitor the building's environmental conditions.
Actuators control heat, light and ventilation to 15 offices and meeting rooms, 10 communal rooms and 300m2 of workshops.
Central control is provided by a single PLC connected on a distributed control network to reduce wiring.
CC-Link was chosen as the operating protocol as it is an open system which can communicate with a wide variety of field hardware.
Touch-screen HMIs allowing users to set preferences for each room and display the current status and historical trends of monitored and controlled devices.
The control system also anticipates building heat demand using real-time clock triggers sent from the HMI to the PLC.
The HMI is linked to GB Innomech's IT network for archiving of trend data and generating alarm and status reports.
Additionally both the control system and the building have been designed to allow for growth, so the company can treble in size without too much difficulty. Request a free brochure from CC-Link Partner Association ...
