• Ethernet Networks Simplified

    May 20, 2014, by Jimmy Coleman

    Setting up an Ethernet network can be frustrating if you don't understand the basics. A network is just the communication connection between two or more devices. These devices can be computers, PLC's, servo drives, HMI's, sensors, cameras…anything that supports Ethernet communication.

  • Modbus TCP with AKD Compared to Fieldbuses

    May 20, 2014, by Jimmy Coleman

    Unlike fieldbus communications only being supported by particular models of the AKD servo drive, Modbus TCP communication is supported by all of the AKD models. Whether you have a simple "analog" drive, an indexing drive, or an AKD with BASIC programming, you have the capability of using Modbus communication. It is a simple, easy to use, standard communication protocol that can be used in a PC, PLC, or HMI to talk to any AKD drive.

  • Key Tips on Dealing with 64-bit data on Modbus Communications Devices that only Support 32-bit data

    September 08, 2015, by Jimmy Coleman

    Most of the AKD drive’s parameters have a 32bit data size, but some parameters have a 64bit data size. Modbus communication on the AKD drive uses registers of a 16bit data size. So for a 64bit parameter, it takes four registers to send the data over Modbus. There are many devices, including PLC’s, HMI’s, and PC programs that do not handle a 64bit data size. So what can be done to read and write 64bit values when working with Modbus and a device that only supports 32bit values?
