Do-More PLC Calculating Uptime

Do-More PLC Calculating Uptime
Machine uptime, also known as machine availability, is when the machine is in operation. This is usually expressed as a percentage.
The uptime percent is calculated by the following:
Machine Run Time / Total Machine Time * 100
The first rung of the ladder logic will zero the machine run and total time. We put in a minimal value so that the divide by zero error is not triggered.
The second rung will increment R0 by one every second. If C0 is on (Machine Running), then R1 is also incremented.
Uptime is then calculated on the third rung.
Downtime percent can easily be calculated by subtracting the uptime from 100.

General information on the BRX Do-More series of controllers:

System configuration tools will also calculate the power budget, I/O count, and price.
BRX Do-More PLC Configuration:

There are several reasons why we are using the BRX Do-More Controller. Here are just a few.
– Standalone PLC with built-in I/O
– Built-in Data Logging
– Communication ability – Ethernet Port, RS232, RS485, USB – support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet)
– Built-in Analog input and output
– Integrated motion control
– High-speed counters
– Powerful instruction set (Video of Instructions in software)
– Ability to expand the system with a variety of modules
– Part of the Do-More series of PLCs which use the same free software. (Do-More Designer)
– Integrated simulator in the software capable of external communications for testing
