Is it just me, or are the years flying by faster than ever?
And as if time is not going by fast enough, I’d like to say how much I'm looking forward to writing this blog at this time next year. Why? Let's just say I can't wait to see what our customers put in the groov EPIC container over the coming year!!
But right now, let's recap the EPIC year of 2024 by looking back at the top 5 most discussed and searched topics in the OptoForums.

### A year in review of the most popular topics and discussions on the OptoForums.
Let's talk for a moment about our fantastic Opto 22 forum fans. The [OptoForums](https://forums.opto22.com/) host an amazing community.
It seems that only a very small number of industrial automation manufacturers run their own public forums. Some community-supported efforts have sprung up to backfill the need for a place where like-minded folks can gather, but there is something special about having a place that is, well, for lack of a better term, "factory supported."
Why is that a big deal?

And the Forums recently went through some reorganization, with more topics and categories added to help you find your answers more quickly and efficiently. Take a look at what's new.

### Get some tips on using the *groov* RIO EMU with other Modbus TCP devices.
The Modbus protocol has been around since the late 1970’s. This is both amazing and cool. Amazing as some reading this have been using it since then (how time flies!). Cool because it's been around so long, and well established and widely used.
Opto 22 products have been supporting Modbus TCP since way-back-when. Out of the box, our devices are Modbus TCP slaves (now called "servers") and can be polled for data on specific register addresses. The [*groov* RIO EMU](https://www.opto22.com/products/product-container/grv-r7-i1vapm-3) (Energy Monitoring Unit), one of our newest products, is no different.

### Learn more about Time Proportional Output (TPO) and how you can use it on the *groov* RIO edge I/O module.
Do you need to control a digital output from an analog input?
If so, perhaps TPO is the solution you seek. Did you know that a [*groov* RIO](https://www.opto22.com/products/groov-rio) has 8 built-in TPO controllers and each can be configured for a different time period? We just need a little setup assistance in the form of a Node-RED flow. Before we get into that, let's talk more about just what TPO is.
