CS1D – Risk Management
OMRON
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…

CJ1 PLC family
OMRON
Fast, Compact, Seamless

Introducing the new CJ1
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.
– Compact size: Free up panel space without sacrificing performance!

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.
1/3 Total
Panel
Volume
2/3 the
Panel Depth
2/3 of the

The CJ1 is a mid-sized PLC in a “micro-sized” package.

How is the CJ1 possible?
OMRON
• Advances in printed circuit board design – More efficient layout.
• New component technology – Lower energy requirements.
• Surface mounted PCB technology – Better heat dissipation.
• New processors – Faster and more energy efficient.

CJ1 Features - Flash Memory Cards
OMRON
• 16 to 64 MB flash cards available.
• Store PLC programs and transfer to/from PLC memory.
• Log data into the card for manual or network retrieval.
• Access the flash card from CX-Programmer – it appears as another PC drive.
• Use FTP to store non-PLC related files on the flash card.

CJ1 Features - Communications

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
by output 100.04. If the pusher is in the out position (limitswitch 0.05) the output goes off and
the pusher returns. During this period no belt is running except the inputbelt.

• 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
