Okuma App Store


Okuma has recently launched an App Store. The site is not just for Okuma-developed apps: products by several THINC partners are featured on the store.

Registration is required to download, but to see the range of possible THINC solutions, you can browse the apps at MyOkuma.com.

Frequently Unasked Questions II

Awhile back, I wrote a Frequently Unasked Questions post, in which I answered questions based on popular search results for this blog.

Since then, the search terms leading to this blog have changed a bit, so here are some more answers to questions that nobody actually asked me…

Checking the installed THINC API version

Hi! This article is very old and outdated. You might consider checking out this updated article.

From time to time, I need an easy way to check the installed THINC API version on an Okuma P200 control.

The problem is that the assembly version numbers don’t always reflect Okuma’s “official” release version number for the installation package. In fact, the Command API and Data API assemblies from the same release usually have different version numbers.

Credit goes to Casey at Okuma for letting me know a simple way of checking the THINC API version as it’s listed on the installation package. The information is stored in the Windows registry, in the uninstall information, so just search HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for the THINC-API entry.

Frequently Unasked Questions

Since the time I created this blog (a little less than a year ago), I’ve checked the site statistics quite a few times. Of particular interest are the search keywords that lead new visitors here: knowing the terms that people search for when they visit this blog helps me understand what type of information visitors expect.

Predictably, many of the terms have to do with machine tools: “MTConnect”, “Okuma”, and “THINC” turn up quite often in the search terms. Others are a little more surprising.

I think of each search term as a question that was never asked. So in this post, I thought I’d take some time and answer a few visitors’ unasked questions.

Remote Access to THINC API, part III

Over the past month or so, I’ve been working on a project to provide remote access to Okuma’s THINC API. Since I’ve been working on this in my spare time, progress has been slow. Still, I started this series more than a month ago, and rather than meandering through numerous future entries, I’m going to try to bring some closure in part III.

So I’ll start at the end. Here’s the finished system…

Remote access to THINC API

For developing custom solutions that run on the control itself, THINC API provides a powerful set of tools. We can read (and often write) a wide range of data: machine status, common variables, tool offsets, and so forth.

If we want access to that same range of data outside of the control, though, our options are a little more limited. For quite awhile, most solutions for remote THINC access were homegrown, and provided access only to the subset of THINC functionality needed for a specific project.

Creating a Panel Mode application for THINC controls

Note: for an updated look at this topic, see this article.

The Okuma THINC controls are advanced CNCs that are based on the Windows platform. This makes it easy to provide solutions using off-the-shelf Windows software. Additionally, Okuma provides a THINC API to enable .NET developers to create new applications that interface with the CNC.

For this example, I’ll develop a simple application that addresses a common problem: changing the CNC panel mode. This is not a new idea: I’ve seen at least three different implementations, and it makes a simple introduction to THINC development.
