Implementing the Omron Host Link Protocol VB.Net

by

Previously we used VB6 (Visual Basic 6) to implement the Omron Host Link Protocol to communicate to our programmable logic controller. (PLC) In part 2 we used Visual Basic for Applications (VBA) to accomplish our host link serial communication. We will now look at using VB.Net to establish and retrieve information in and out of … Read more

Omron CP1H Numbering Systems and Addressing

by

The Omron CP1H series of programmable logic controllers have a fixed input and output addressing system. Every PLC has its own way of addressing its inputs and outputs. We will be looking at how the CP1H series of controller addresses its inputs and outputs. Numbering systems used in this controller will also be looked at … Read more
