Risk Management is essential in

systems

requiring a high level reliability.

Every system is subjected to malfunction When is this a significant problem?

•24 hour system that can not be stopped •Extremely high starting-up costs

•Unexpected stops can lead to disasters

e.g. toxic spills, explosions…

OMRON

•A SMALL PLC in size, but it is not a MICRO…

•PLC size and capability no longer go hand-in-hand!

•The CJ1 features:

– High speed CPUs (40 and 20ns):

20ns is 3 to 5 times

faster than typical mid-sized CPU. (e.g. C200H series)

– Control up to 2560 Local I/O:

Typical of the mid-sized

PLC category.

– Industry leading networking:

Omron’s FINS protocol

routes data across networks.

(27)

OMRON

• In fact the Omron CJ1 is a CS1 in a smaller

package.

– Released in 1999, the CS1 is and will remain

Omron’s mid-sized PLC and leading technology

platform.

Products on the inputbelt are transported to PES 0.00. This belt stops if there is another product under work. Otherwise the product is transported to the next belt and stops if PES 0.01 detects the product. The drill is in the upper position and will be started by output 100.02.

The drill goes down to limitswitch 0.02. The output 100.02 is set to off and the drill is returning to the upper position. If upperlimitswitch 0.03 detects the drill, the inputbelt, the transportbelt and the outputbelt is started. PES 0.04 detects the product and stops the outputbelt on the backside of the product . After five products the pusher is activated and pushes the products from the belt

Interrupt Task

• Interrupt of cycle task execution

can be triggered by

– Power fail

– Internal timer

– External interrupt input

– Message received on serial

Task programming

• When to use Tasks?

– Local symbols results in flexible programming

– Parallel program development

– Reuse of standard blocks of code

– Upgrade of the machine by activating the task

– Optimisation of the cycle time
