Let's say you have four pumps available, and you don't run them all at once. When it's time to start one, you want to choose the one with the least wear.
You can decide which one to start by comparing the total amount of time each pump has run. That's a job for a totalizer.

A SNAP PAC controller communicates over Ethernet. Is it OK if two PCs are trying to communicate with the PAC at the same time, or will they interfere with each other?
This was the question in a recent OptoForum post, and it got a quick answer: yes, it's OK.
Whether it's a standalone S-series or a rack-mounted R-series PAC, you can have many devices simultaneously requesting data from and sending data to a SNAP PAC.

When you turn on an output, do you set a flag and then check it to see the output's status before turning the output on again?
Or do you just turn it on without checking?
Is setting a flag a good way to speed up the program and avoid tying up the network with unnecessary communications to I/O?
Or does it just add a lot of extra variables and decision blocks that make debugging and maintenance harder?
