PLC Controller Firmware Upgrade
When you buy the plc CPU for the first time, you need to upgrade to the appropriate version for your program. If your program is written with version 30, you need to upgrade your CPU to version 30. CPUs come as version 1 by default. You can easily upgrade the CPUs of PLCs with Firmware…
Connect to PLC via USB cable
If the controller (usually 1756-L7x ControlLogix and over ) has a USB port that uses a Type B receptacle. The port is USB2.0 compatible and runs at 12 Mbps. to use the USB port of the controller, you must have RSLinx® software, version 2.56 or later, installed on your workstation. Use a USB cable to…
PLC First Scan Bit
What is First Scan Bit and How to create a tag? This bit is activated every time the PLC switches to run mode, as the name suggests, the first scan bit. You don’t need to create any tags for the first scan bit. When we look at what we can use this bit for; Where…
Siemens PLC Programming, S7-300 and S7-400 (SIMATIC S5) PLC
Communication Modules Communication modules provide data exchange between PLCs and input-output units or between other personal computers. These modules can be operated by direct connection (point to point) or over a network. In a one-to-one connection, the connected processor includes a dual interface. While one computer port is accessed by the programming device, communication is…
How to get data from plc to excel
How to communicate with PLC via Excel? In order to get data from PLC with Excel, we need to use OPC. If you are using Rockwell Allen-Bradley plc, no other tool is required for OPC because we can transfer data from Allen-Bradley PLCs via OPC with the RSlinx application. Note that the RSLinx application we…
PLC Function Blog Diagram (FBD)
Function Blog Diagram, whose short name is FBD, is not a highly preferred type of PLC programming language, but it allows us to do even the longest operations in a short way in most places and is easy to interpret. Although Function Block Diagram type is not one of the most commonly used PLC programming…
