Can u help me to build this program by using fpwing.gr?plss..i need it
thanks if u can help me..
The PLC program simulates a process tank being filled with a fluid. The tank will start
filling (via a valve) whenever the start process button is enabled and the tank is below
50% full. It will shut off when the tank is 100% full. In case the level sensor is out of
calibration or not working properly, there is a high-level safety limit to prevent the tank
from overfilling. If the high limit is met at a preset value of 102% full the process will
shut down and a strobe light will turn on. Indicator lights are activated when the tank
level reaches 50%, 75% and 100% full as shown in the diagram of the tank in Figure 1.
There is a slight dead band to prevent flickering lights when tank levels vary slightly due
to filling or splashing.
If the tank for some reason does not fill up to a minimum level of 50% within 5 minutes
after the valve energizes, an alarm will notify an operator. The operator will be able to
silence the alarm for 5 minutes by pressing a silence button. After five minutes the alarm
will trigger notifying the operator once again. The operator will be able to silence the
alarm two times. If the silence button is pressed a third time, the alarm will remain on and
an energized strobe light will notify anyone within the site of the tank. The silence button
will be tamper proof by utilizing a one-shot rising instruction to prevent an operator from
holding the button in. If the tank remains under 50% full, the only way to de-energize the
alarm and strobe is to stop the process...
