become accurate and quicker. Along go forward technological and to the number of appliance of electrics

make we will progressively more amount learning to pursue technology. One of very technology needed by

a company for example is Programmable Logic Controller or PLC. This PLC represent a electrics peripheral

which is good for as control in system network or wear command in course of production. One of brand

from PLC is OMRON, SIEMENS, MATSUSHITA, TOSHIBA, MITSUBISHI, and other.

PLC is represent an equipments control electronic created from result of solidarity of among computer

technology " solid-state " and " traditional sequence controller " . If visible from computer used, PLC is

special purpose group. Computer special purpose is designed special tools to process certain problem, for

example inspection equipment.

Basically PLC have function to replace job from relays mechanic and timer or switch manual. Because

by excellence from micro controller equipments develop hardware, hence PLC can operate arithmetical,

converting data from analogue to digital or on the contrary, and can finish control problem having the

character of complex. To correspond to job circumstance, hence PLC designed to can operate on dusty

industry environment and mount high pollution, with temperature change 0 - 60oC and the dampness

relative at 0% - 95%.

TIM or TIMH(15) are decrementing ON-delay timer instructions which require a TC number and a set value (SV). Any timer can used to control the interval timers, which are used to activate interrupt routines.

Any one TC number cannot be defined twice, i.e., once it has been used as the definer in any of the timer or

counter instructions, it cannot be used again. Once defined, TC numbers can be used as many times as required as operands in instructions other than timer and counter instructions.

A timer is activated when its execution condition goes ON and is reset (to SV) when the execution condition goes OFF. Once activated, TIM measures in units of 0.1 second from the SV. If the execution condition remains ON long enough for TIM to time down to zero, the Completion Flag for the TC number used will turn ON and will remain ON until TIM is reset (i.e., until its execution condition is goes OFF). The following figure illustrates the relationship between the execution condition for TIM and the Completion Flag assigned to it.

CNT is used to count down from SV when the execution condition on the count pulse, CP, goes from OFF to ON, i.e., the present value (PV) will be decremented by one whenever CNT is executed with an ON execution condition for CP and the execution condition was OFF for the last execution. If the execution condition has not changed or has changed from ON to OFF, the PV of CNT will not be changed. The Completion Flag for a counter is turned ON when the PV reaches zero and will remain ON until the counter is reset.

CNT is reset with a reset input, R. When R goes from OFF to ON, the PV is reset to SV. The PV will not be decremented while R is ON. Counting down from SV will begin again when R goes OFF. The PV for CNT will not be reset in interlocked program sections or by power interruptions.

Whenever executed, DIFU(13) compares its current execution with the previous execution condition. If the previous execution condition was OFF and the current one is ON, DIFU(13) will turn ON the designated bit. If the previous execution condition was ON and the current execution condition is either ON or OFF, DIFU(13) will either turn the designated bit OFF or leave it OFF (i.e., if the designated bit is already OFF). The designated bit will thus never be ON for longer than one cycle, assuming it is executed each cycle (see Precautions, below).

Whenever executed, DIFD(14) compares its current execution with the previous execution condition. If the previous execution condition was ON and the current one is OFF, DIFD(14) will turn ON the designated bit.

Programming Console screen.

No key operations can be performed while the mode display is displayed on the Programming

Console screen. Press CLR to clear the display so that key operations can be performed.

If the SHIFT Key is pressed while the mode switch is turned, the original display will remain on the

Programming Console’s screen and the mode display won’t appear.

8. Input Indicators The input indicators are lit when the corresponding input terminal is ON. The indicators are lit during I/O

refreshing. When a fatal error occurs, the input indicators change as follows:

Note

a) When interrupt inputs are used in interrupt input mode, the indicator may not light

even when the interrupt condition is met if the input is not ON long enough.

b) When high-speed counters are used, the input indicator may not light if the input pulse is too fast.

9. Output Indicators The output indicators are lit when the corresponding output terminal is ON.The indicators are lit during I/O

refreshing. When pulse outputs are being used, the indicator will remain lit continuously while the pulses are

being output.

Power Supply Wire a separate circuit for the PLC’s power supply circuit so that there isn’t a voltage drop from the inrush current that flows when other equipment is turned on. When several PLC are being used, it is recommended to wire the PCs on separate circuits to prevent a voltage drop from the inrush current or incorrect operation of the circuit breaker. Use twisted power supply wires to prevent noise from the power supply lines. Adding a 1:1 isolating transformer reduces electrical noise even further. Considering the possibility of voltage drops and the allowable current, be sure to use thick power lines.
