Curious to get your hands on a凹槽EPIC learning center（LC）? So was I. Lucky me, this was dropped off at my cubicle recently. Let’s see what’s inside!
建造
The case is surprisingly rugged, fit for travel. According to Pelican’s site, if you can’t sink it, drop it, or kick it, it isn’t a Pelican case, and from the feel of it, that’s accurate. It’s solid, and takes an effort to open the latches.
Inside, I see the back of the controller and plexiglass stand packed in high-density foam. Included with the controller are some instructions, which, like any good experimenter, I immediately set aside.
我抓住看起来像手柄的东西，然后拖船。有一些阻力，但控制器直接抬起。在尝试弄清楚如何安全地将其放下后，我注意到锁定引脚并最终检查说明以找出如何使用它。
After a couple maneuvers, I get the unit upright. In the image below, you can see the two pushbutton/LED indicators, potentiometer and ICTD coupling. Removing one more layer of foam from the case, I find the power adapter and temperature probe and get everything connected.
Time to awaken the machine… (It’s not happy)
启动后……（一切都更好！）
Configuration
点击“让我们开始”之后，我选择了“快速启动”选项，该选项使我创建一个管理员名称和密码。不过，我必须有一些脂肪的东西，因为第二天，它不会接受我认为使用的密码。由于没有默认管理帐户，因此我唯一的选择是重置处理器并重复配置。这只需要几分钟，我借此机会将设备移至办公桌并安排我的网络。
完成此操作，我可以从浏览器中完成设置。处理器已通过DHCP获取IP地址，但是我尝试使用默认的主机名。它可以正常工作，我遵循随附的说明来激活和安装许可证。当我使用时，我拿起最新的固件并安装。我在Manage.groov.com使用随附的激活键。
作为最后一步，我设置了一个没有管理特权的演示用户帐户。默认权限非常限制，似乎该用户只能启动凹槽View。
现在，该设备全部设置了，我探索了I/O模块。直流输出卡上有一大堆电线，因此我将其前盖移至扩展位置。您可以看到它在LC下面的图像中略微坐在其他的前面，坐落在我办公桌上的永久性房屋中。
接下来，我需要加载PAC项目和CODESYSon my PC so I can put this bad boy through its paces. I also really want to tryMQTT与之沟通节点红色。More on that in another post.
结论
I’m glad to have my LC ready to go. It was quick to set up and will be useful for testing and training as I familiarize myself with everything凹槽史诗可以做。我也真的很喜欢构建质量，而且在我的桌子上看起来不错。Opto 22喜欢硬件，我认为这在该产品中很明显。看一下Opto 22 product selectorto find more than 700 finished goods made on site. Here are the folks that built mine:
只是为了娱乐，这是Opto 22的其他面孔及其令人敬畏的测试钻机。
Opto 22. By engineers. For engineers.
See you next time!
