Open Discussion / Comms Omron CP1h and Advanced HMI using Modbus RTU

« on: April 18, 2025, 11:17:10 PM »

Have been struggling to communicate between Advanced HMI and CP1h. Tried easy modbus but could not get it to work. Felt unsure about setting up the PLC in master or slave. Eventually I found the official Modbus RTU slave on an Omron website and included it in my program. Still could not get it to go. Found that the PDF that comes with the FB states right hand comms port on the PLC states right hand port is &2. When I set up my FB using port &3 modbus came to life. A few weeks further down the track I have a fully operational operator interface. I am using a temperature controller from the toolbox with the built in push buttons for auto manual control selection and setpoint selection. The controler works in conjunction with a the PID instruction in ladder. I am chuffed with AHMI. Thanks Gary.

Thanks Archie, have followed up your suggestion, no luck. Have uninstalled/re installed Visual Basic and started with a freshly unzipped copy of AHMI. Configured a gauge, works OK on modbus RTU. Configured a chart by sampling, did a build solution. Same list of errors pops up. Have attached the full error listing.
I am using AHMI vs 3.99Y , Microsoft Visual Studio Community 2022 (64-bit) - Current

very much appreciate your help

Open Discussion / Chart by Sampling function

« on: December 14, 2024, 10:42:05 PM »

Hi, I am running an Omron CP1h using AHMI on Modbus RTU. My AHMI main form shows the data I have coming in through two analogue inputs.
I am trying to display the AI data using "chart by sampling function" but get hopelessly stuck configuring the chart. When I click on Data, it takes me to an area where i have to select one of three options? Is there anyone that is able to help me on my way. Is there an instruction set associated with this aspect of advance HMI
I have attached the error file showing errors associated with my efforts.

Really appreciate the content of this forum, have helped me a lot getting up and running.
