to all PLCS gurus, pardon a question from a newbie..
1.) A conveyor will be controlled by a motor speed controller, to be specific a gear motor speed control & linked to the plc.. this motor is an ordinary motor only, with a rotary knob use to vary its speed.. as part of its system improvement,we will install an improvised rotary encoder (using a rotary plate with a number of punches & a photosensor).. how will i be able to control this rotary encoder on a ladder?
2.) I am tasked to modify a certain machine.. Part of the system sequence is the control of 3 heaters.. I have a SV set on the temperature controller, when my sensor "says" that there is no enough temperature 1 heater will turn on.. Agen, the sensor detects temperature, if still not enough my second set of heaters will turn on.. And agen, my sensor detects, if stil not enough, my last set of heater will turn on.. With this sequence, will my temperature controller be enough in controlling the system temperature without linking it to the PLC?
PLEASE HELP
