· of PLC over Relay Logic 1 Flexible control change any industrial process by modifying the program 2 Maintenance and the discovery of faults in the PLC system are easily seen on the PLC screen 3 Small size 4 Has characteristics that are not available in normal computer 5 Ability to engaged with other PLC
to implement fuzzy control to control the speed of belt conveyor system The PLC used was OMRON PLC which requires additional Fuzzy logic unit C200H FZ001 to implement the fuzzy logic control Special software was also required to program the knowledge base and a subprogram for ladder diagram must be prepared for transferring data between the
· Structure of PLC Based PID Speed Control of DC Belt Conveyor System 24 Experimental Setup for PLC Based PID Speed Control of DC Belt Conveyor System 24 PLC s Structured Programming for PID Controller 25 xi PID Programming 26 Process Reaction Curve from Open loop Test on the
2 ·Assume time by calculating conveyor belt speed When number of parts to be packed are detected timer is activated When timer is over it stops the conveyor until next empty box is detected PLC Algorithms To practice all PLC programs here is complete set of 100 PLC Problems and Solutions « Prev PLC Program for Counting of Parts from
·The PLC program containing the PID controller and the control program created in LabVIEW work simultaneously to provide speed control of the motors that move the conveyor belt The PWM signal that rotates the motors was applied by the PLC and the feedback signal from the encoder adjusted the PID controller output signal at the desired speed
·I have a pnematic cylinder that pushes things onto a conveyor belt I have push buttons to start and stop the conveyor I have cylinder swithc to the cylinder I want to write a logic to extend the cylinder I don t have any other inputs to give signal to the cylinder The start push button starts the conveyor which inturn turns the green light of the push button Is there any
