Hi there! I'm curious if there's a standalone alternative to using an ethernet cable for connecting to a PLC. Is there a "dongle" available that I can connect to my PLC and another to my laptop to create a wireless connection? This way, I can easily bring my laptop with me to the machine. I'm looking for a simple solution that doesn't require multiple routers, as I visit various factories.
I utilized Bluetooth technology for my machines in a cleanroom to avoid the hassle of dressing up and being physically present in the room. With the convenience of being able to control the machines from outside the room through a window, I found it to be effective. I believe Bluetooth technology has advanced significantly since then, making it worth considering a Bluetooth adapter for improved connectivity.
Consider investing in a portable Wi-Fi router, as many individuals in online communities have recommended this solution in the past.
To improve network connectivity, I set up a cost-effective WiFi router by disabling DHCP and assigning a static IP within the PLC subnet. I also configured my laptop with a static IP for a seamless connection. Adjusting the IP address may be necessary depending on the specific PLC or system setup, but it's a quick process.
In order to establish a WiFi connection, it is essential to have a WiFi Access Point configured in client mode. This will allow you to connect to an existing wireless network and access the internet seamlessly.
When setting up a WiFi router for a PLC system, it is important to disable DHCP and assign a static IP address within the subnet. By connecting a laptop with a matching static IP, the setup process can be quickly completed. It may be necessary to adjust the IP address depending on the specific configuration of each PLC or system. Utilizing a reliable router like the MikroTik RB952Ui-5ac2nD can ensure smooth operation. In situations where mobility is required, a micro-USB to ethernet adapter can be used instead of relocating the router for each job.
Absolutely, there are indeed wireless alternatives to ethernet cables for PLC connection. You can use a WiFi adaptor, designed to convert ethernet signals into WiFi. These 'dongles' simply plug into the Ethernet ports on both your PLC and laptop and communicate wirelessly. Just ensure the one you choose matches your PLC's communication protocol for seamless operation. Note, however, that the reliability and speed might not be as robust as a hardwired ethernet connection, and you'll need to consider possible interference in a factory setting.
You might want to consider a wireless adapter or even a WiFi extender with an Ethernet port. If your laptop has WiFi capabilities (which most do) and the distance between your laptop and PLC isn't too large, this could help you establish a wireless connection. Just plug the Ethernet cable from the PLC into the adapter/extender, then ensure the adapter/extender is within WiFi range of your laptop. Netgear and TP-Link offer some reliable solutions you might want to check out.
