各种类型的以太网很常见，包括有线和无线，但PLC必须连接到其他平台，包括iOS和Android，以便与智能手机和平板电脑进行远程访问。在许多应用中，向控制室发送操作员警报已经不够了。现在，PLC需要向技术人员或经理发送文本消息或电子邮件，或者向浏览器提供网页，无论这些人可能在哪里，也无论他们希望使用什么联网设备。

甚至PLC的配置和编程也变得更加简单。有了蓝牙，技术人员甚至不需要带电缆来连接笔记本电脑。通过适当的授权，现在可以站在设备旁边进行更改或调整，甚至不用触摸它。

考虑到程序的大小和PLC现在可以容纳的数据量，作为FTP客户端或服务器的功能是必须具备的能力。这使得移动大块代码或历史信息变得更加容易。

所有这些通信方法都是“经得起未来考验”的技术，因此当需求变得越来越复杂时，它就能准备好。接入互联网并作为物联网或工业物联网的一部分的能力已经扩展到各种工业设备。PLC现在需要能够支持远程访问，包括在一个旨在提供高度网络安全的框架内管理访问和用户的能力。

Various types of Ethernet are common, both wired and wireless, but PLCS must be connected to other platforms, including iOS and Android, for remote access with smartphones and tablets. In many applications, sending operator alerts to the control room is no longer enough. PLCS now need to send text messages or emails to technicians or managers, or provide web pages to browsers, no matter where those people may be or what connected device they wish to use.

Even the configuration and programming of PLCS has become easier. With Bluetooth, technicians don't even need to bring a cable to connect a laptop. With proper authorization, it is now possible to stand next to the device and make changes or adjustments without even touching it.

Considering the size of the program and the amount of data the PLC can now hold, the ability to function as an FTP client or server is a must have capability. This makes it easier to move chunks of code or historical information.

All of these communication methods are "future-proofed" technologies, so it will be ready when requirements become more and more complex. The ability to access the Internet as part of the Internet of Things or the Industrial Internet of Things has expanded to a wide range of industrial devices. PLCS now need to be able to support remote access, including the ability to manage access and users within a framework designed to provide a high degree of network security.
