*There are two input ports F1H and F2H and one output port FOH.
*All the switches of F1H&F2H are connected to the data line Do to D7 of 8085 microprocessor.
*All DO to D7 lines of 8085 are connected to 00 to 07 of output port.
Write program for the following instructions:
1.
Only when both the SO switch of F1H & F2H are ON, the 04 to 07 belts should be ON
irrespective of the conditions of both S4 to S7 switch positions.
2.
If the both the SO switches are on, the P-ON light should be enabled followed the conveyer
belt operation.
3. When the conveyer belts are started to process, the M-ON light should the indicated.
4. If there is any emergency condition, E-On alarm should be enabled followed by the switching
off the conveyer belts.
5. If the conveyer belts are stopped, the P-OFF indicator should be enabled.
