We will now use AdvancedHMI to communicate to our Omron CP1H controller. Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is that the software is free. We will look at using AdvancedHMI with the Omron CP1H PLC.
Our sample CP1H PLC program will use buttons and indicators to control a start/stop jog circuit. An analog input into the PLC will be scaled and displayed on a gauge on our AdvancedHMI screen. We will also write information to our 7 segment display on the CPU from our AdvancedHMI screen. This communication will be done using Omron serial host link protocol over an RS485 serial cable. The AdvancedHMI package will run on a windows PC and communicate out the port using a USB to RS485 adapter.
AdvancedHMI can communicate to many devices. The CP1H PLC can communicate Host Link (C Mode Commands) Serial – RS232, RS485, RS422. It can also communicate Ethernet FINS via a communications module. Communications drivers currently included in AdvancedHMI are as follows. These drivers are fully accessible via VB or C# code:
• Allen Bradley DF1 RS232 Driver
• Allen Bradley Ethernet/IP Driver for SLC, MicroLogix, ControlLogix, and CompactLogix
• Beckhoff TwinCAT Driver
• ModbusTCP Driver
• Modbus RTU Driver
• Omron Ethernet FINS Driver – Ethernet for newer controllers such as CP1H with Ethernet module
• Omron Serial FINS Driver – Serial (RS232 / RS485) for newer controllers such as CP1H
• Omron Serial HostLink Driver – Serial (RS232 / RS485) for controllers such as CQM1, C200H, K-Series (C28K), C200, etc
