Allen Bradley 1770-KF2

Do you want the old equipment in the factory that only understands "dialect" (DH-485 protocol) to communicate with the new computer system that only understands "Mandarin" (Ethernet)? The Allen Bradley 1770-KF2 is precisely such a "communication magic tool". It does nothing else but act as a translator, seamlessly transferring the conversations between the two sides, allowing the old equipment to shine in the new system. Since this is such a crucial bridge, be sure to keep your eyes open when buying. As a reliable supplier, we assure you that every unit provided here is an original and brand-new quality product. With our "magic tool", you can confidently establish a smooth connection between the past and the present, and no longer have to worry about communication problems.

Product parameters

Core function

In the end, the Allen Bradley 1770-KF2 does only one thing: translating. The older PLCs in the factory, such as the SLC 500, can only speak "dialect" (DH-485), while the current computers and touch screens can't understand it. KF2 is in the middle. The computer speaks Mandarin, and it translates it for the old PLC; the old PLC replies in dialect, and it then translates it back into Mandarin for the computer. It doesn't interfere on its own; it's just a faithful messenger, ensuring that the communication between the two sides is error-free. The most amazing thing is that once it is connected to the network, several computers in the office can simultaneously chat with that old PLC, and there is no longer the need to queue up for a data cable.

Ease of use

When using this device, the Allen Bradley 1770-KF2's quite convenient for engineers. The wiring process is just three steps: plug in the power supply, connect the dedicated cable to the old PLC, and then plug in a network cable to the switch. That's it. Installing the software is also simple. Just open the Rockwell software called RSLinx, click a few times on the mouse, enter its IP address and the PLC number you want to connect, and they will be able to communicate with each other. The entire process doesn't require you to write a single line of code. It's similar to setting up a game, and you'll be able to figure it out in no time after a little tinkering.

When it comes to "translation", the most dreaded thing is getting the wrong message across. The quality of this thing lies in its reliability. First, it is directly produced by Rockwell and is a "sibling" to the company's old PLC. They communicate naturally and always work well together, rarely failing. Second, it is robust and industrial-grade.

Typical application scenarios

This thing is used in the factory mainly to "revitalize old equipment". For instance, in your workshop, there is an old piece of equipment controlled by SLC 500, which is running perfectly. But now the boss requires that all data must be uploaded to the new production management system (MES). What should be done? Replacing the entire equipment is too expensive! With a Allen Bradley 1770-KF2, the data of the old equipment can be "translated" onto the internet, and the new system can read it. Another example is that a key piece of equipment is located at the very end of the production line. Every time there is a problem with the program, the engineer has to carry a laptop and rush over there, getting extremely tired. With it, the engineer can remotely debug from the office while drinking coffee, which is very convenient!
