Because of the large number of features in IMAC it is sometimes difficult for customers to keep up to speed with them.For this reason we have decided to send out periodic news letters to highlight some of the features which we hope may be of interest.
New.....We have enhanced the IMAC Frequency Analysis software to:
Run over much shorter time scales (this used to be fixed at 24 hour intervals, it is now available with Hours and Minute resolution)Provide completely new and powerful statistics on alarm rates and operator work loadThe new statistics are displayed like this:BackgroundMost customers have the Frequency Analysis software module already installed.
Count Identical Alarms Over Time Display Results Over Time All Red Alarms are identical. All Green Alarms are identical. Black Alarms are other alarms or events.
For those not familiar with the module, it counts the occurrence of identical alarms over time and can very quickly highlight nuisance alarms which turn on and off without being genuine alarms which require operator attention.This is a very powerful tool and has proved invaluable in pinpointing problem alarms.
Frequency analysis has now been modified to run over much shorter, selectable time ranges than was previously possible.What's new is that we have just completed further modifications to the frequency analysis to include what we believe will be an even more powerful tool.Safety issues in particular have led many people to look very closely at their alarms to try to prevent overloading operators with alarms during a plant disturbance.The EEMUA (Engineering Equipment and Materials Users Association) have produced a document called "Alarm Systems a guide to design, management and procurement" Publication 191 which many engineers are using as their starting reference in an alarm management strategy. This is not a free publication but can be purchased from EEMUA at http://www.eemua.co.uk/publications/order.htm It is a very useful document with good practical suggestions.
One of the principal guidelines in this document suggests monitoring the rate at which alarms are generated, both in a steady state and following a plant disturbance.Their suggested targets are :Less than 1 alarm per 10 minutes during steady plant operation.Less than 10 alarms per 10 minutes following a plant disturbance.Our latest modifications will enable you to assess how your own plant performs in these circumstances.
It will count ALL alarms over various selectable time periods and display the results as a bar graph and table.It's possible to over lay one graph on top of another to show operator actions as well as alarms.
This quickly shows the operator work load superimposed on top of the alarm rate.
If any of the bars in the graph are selected, the window underneath will show all the alarms which have arrived in that time slice.
This shows what alarms are represented by a specific bar on the graph.
The display also shows other additional alarm statistics which should prove very useful.Customers with systems less than 1 year old and those with continuing support contracts in place will be able to down load this enhanced Frequency Analysis module FREE OF CHARGE now in IMAC V2.82 from our web site. For those without support contracts this would be an ideal opportunity to put one in place.Contact us today for more information or a quotation by return.
