PLC Program to Count Running Hours of any Equipment

This is a PLC Program to count running hours of any equipment using bit instructions, math instructions, and counters.

PLC Running Hours

In industry, it is sometime necessary to count running hours of any equipment (pumps, compressors, motors) to maintain its efficiency, equipment life as well as periodic maintenance. By using PLC instruction we can prepare a PLC program to count the running hours of any equipment.

PLC Programming

Here is the PLC program to count the running hours of any equipment.

Network 1:

This network adds the 1 second at every 1-second pulse when there is running feedback of equipment and there is no reset bit.

Network 2:

This is the network that converts seconds into the hour.

Network 3:

In this network, we are getting the remaining second by mod instructions and then convert it into minutes.

Network 4:

This network converts minute into seconds.

Network 5:

These two networks are for reset logic. When there are 1000 hours in the count it will add count up by 1 and reset all the counting by just moving 0 to an hour, minute and second.
