Implementing the Omron Host Link Protocol VB.Net

We will be implementing the Omron host link protocol vb.net. Hostlink communication protocol is a method developed by Omron for communication to PLCs and other equipment. This ASCII-based protocol is used over RS232 or RS422/RS485. It is a many-to-one implementation which means that you can communicate with up to 32 devices back to a master. (1:N) This communication on the industrial floor can control PLCs, Temperature Controllers, Panel Meters, etc. The Omron CP1H plc will be used with a CP1W-CIF11 (RS485) communication serial link adapter. We will also use a USB-485M Universal Serial Bus to RS485 adapter from automation direct. The video at the end of this post will demonstrate the communications by reading 10 registers from the DM area of the PLC. More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net Previously we used VB6 (Visual Basic 6) to implement the Omron Host Link Protocol to communicate to our programmable logic controller. (PLC) http://accautomation.ca/how-to-implement-the-omron-plc-host-link-protocol/ In part 2 we used Visual Basic for Applications (VBA) to accomplish our host link serial communication. http://accautomation.ca/how-to-implement-the-omron-host-link-protocol-part-2-vba/ We will now look at using VB.Net to establish and retrieve information in and out of the PLC using host link.
