PLC Practical Assessment
Create a PLC program that will meet the following criteria when run under the “simulation” mode on any of our PLC
stations.
Set the alias for each of the following inputs and outputs as shown below:
Absolute Address
Alias
_IO_EM_DI_00
PB1
_IO_EM_DI_01
PB2
_IO_EM_DO_01
Green Lamp
_IO_EM_DO_02
Red Lamp
_IO_EM_DO_03
Yellow Lamp
General PLC Sequence:
Pressing and holding PB1 for 7 seconds will cause the Red Lamp to light up.
When the Green Lamp has been lit for 5 seconds, it will cause the Yellow Lamp to light up.
When the Yellow Lamp has been lit for 3 seconds, it will cause the Green Lamp to light up.
Pressing PB2 at any time during the sequence will cause the process to stop.

done!
