啤酒和季节

在我的最后一篇文章中绿色潜艇traveled through space and time to the bottom of the ocean, and an Opto 22Snap pac(programmable automation controller) interfaced with a lot of Modbus equipment to coordinate systems。

These next two adventures are also examples of how well Opto 22PACs和别人一起玩。

More beer, here...

这是我特别喜欢的物联网（物联网）应用程序。它将自己的啤酒或其他饮料分配器连接到相关的云。

So there you are on a cruise ship in the middle of the ocean. You can just walk up to a serve-yourself dispenser and get the brew you want.

分配器将您的数据发送到云中，该系统会自动检查您的年龄，记录您的啤酒数量并为您的卡收费。

谢谢，绘图呢

And yes, I did think about how I might add just a little bit of extra code in that application. It would be so easy to addif name = OptoMary,then let her have as much as she wants—and don’t bother adding it to her bar tab in the cloud.

但是我当然没有。（那是我的故事，我坚持下去。）

The cloud to connect to on the cruise ship was a small local server. That server just required some XML/SOAP packets for the necessary transactions.

但是我们的PAC Controlcommunication commands also support secure TCP communications (like HTTPS GET and POST requests) and have for many years now. So the cloud can be anywhere.

And that means any communication code I may or may not have contributed some years back is now in applications all over the world, communicating with various hospitality protocols and systems, pouring joy and happiness for all. Especially OptoMary.

例如，相同类型的云连接分配器一直在填充啤酒眼镜在美国职棒大联盟比赛中。那got lots of press.

这导致了我的下一个最喜欢的客户-ODD，因为我本人并不是一个庞大的体育迷。

半场表演的力量！

我在这个功能强大的项目中学到了一套全新的首字母缩写词和条款，包括MLB和“后季节”，这听起来像是“全部结束之后”的意思，但实际上，这变得更加令人兴奋。

Post season is also (coincidentally) when the higher-ups in the major leagues-and certain sports broadcasting folks-are especially concerned about making sure the power stays on for the entire game. So we got involved.

该集成项目涉及一些PAC控制OptoScript代码以保留事物的选项卡（这次不是我的栏选项卡）。但这主要是凹槽project, since凹槽is made for mobile and those TV execs wanted to be able to see "All power systems go" right from their smartphones and big TVs.

他们想监视和控制的大多数功率，UPS和发电机设备都使用Modbus协议（主要是Modbus/TCP）， 哪个凹槽does natively. So they didn’t need that much help to type in addresses and registers, then drag and drop gadgets onto their web pages for those TV monitors and handheld devices.

This MLB凹槽project was a nice little warm-up for大型游戏（我了解到，除非您支付健康的许可费，否则您不应该用其通用名称来打印），在那儿，几个团队穿着紧身裤子在球周围扔紧身的裤子，可能会被完全夸大。

Result? The power stayed on the whole game, and the VIPs got the powerful reassurance they needed.

Also, Lady Gaga put on a super high-tech halftime show.I wouldn’t be surprised if some Opto hardware was involved there, too. We often have at least a relay in the mix without even knowing about it until decades later, when someone opens a box that’s been working away quietly, underappreciated, like a few integrators I know.

但是我离题了。

Happily learned lesson

虽然初稿的应用程序需要一些精美的TCP通信处理和OptoScript来构建XML/SOAP数据包，但如今，这一切都变得更加容易。使用内置的HTTP GET和HTTP POST命令在PAC控制本身中，以及与无数的连接选择节点红色^®in the凹槽盒子，，，，building物联网应用比以往任何时候都容易。

第二个凹槽application for power turned out to be the first time in history this championship game ever went into overtime. (Maybe凹槽+ Opto = good luck for fans?) Since I knew all about the last-minute changes (from many phone calls I’d received while helping the integrator put the final touches on their solution), I watched with an extra level of excitement.

与某些前几年的比赛不同，在2017年，即使有额外的加时赛，灯光一直保持着。哇！人群疯了！
