Temperature is a very important part in the process because it is an indicator of thermal energy in the process. The temperature is controlled by a temperature controller, which is well known.

Omron speed temperature E5CN

There are many many brands of equipment to be controlled, such as boiler water temperature increases slowly. Process kiln drying rooms, storage rooms, freezers and refrigerator with these temperature changes slowly.

To select the device may be determined by the behavior of the precision and durability, but need not delve too much control over the speed of operation. Of course, the controller can calculate and send a signal to the heater or cooler than the temperature changes very quickly.

But if your job is changing rapidly, such as heat seal packaging machine’s heat. Hot-wire cutting. Transport of heat by steam. The temperature can change quickly, this is a controller that is running at high speed. (more…)

PLC ladder Exemple and PLC programming and PLC training and programmable logic28 Jul 2011 08:26 am

Omron PLC tips today,I would like to suggest a better Instruction available in CX-Programmer , Omron PLC was wrote ladder or programming with CX- Programmer . Could you used the Instruction Name and in this instruction , I can define the SET and RESET conditions at same rungs.
See the Below Picture.

Remark :- You can click on the picture for a large view.

If W2.0 turns ON, the designated bit will go ON and stay ON until reset, regardless of whether W2.0 remain ON or goes OFF. but if W3.0 turns ON, the designated bit will go OFF.(w4.0)

Hi PLC developper ,For PLC programming example today is Flashing circuit.

The ladder diagram is an oscillating circuit which makes the indicator flash or enables the buzzer alarms.
It uses two timer to control the On/Off time of coil Y1.
n1 and n2 refer to the set values in T1 and T2 and T is the cycleof the clock.
