Support Questions / 12 Bit Analog to Modbus Coils

« on: January 10, 2016, 07:36:58 PM »

I am in the process of developing a HMI that reads and writes Modbus values to a Crevis field IO device. The analogs on this device come in as a 12 bit register on 12 Boolean bits. I am having trouble using a datasubscriber to get this information in and processed. Any thoughts??

Support Questions / ModbusTCP Polling problem

« on: December 03, 2015, 05:52:32 PM »

I do alot of testing at work for the combustion systems that we manufacturer. I have used AHMI to mimic both our testing PLC and our DCS system. During our Factory Acceptance Testing (FAT) we have both BV and clients here to supervise the testing. The idea behind using AHMI is to make it more graphical and to be a more realistic type of testing, basically have the feel of what it will be once the equipment is commissioned on site.

My problem at the moment is that i am trying to poll roughly about 300-400 modbus TCP points. Even with the poll rate down to its lowest setting the modbus is terribly slow. What i have worked out is that it seems to illiterate through each point polling them one by one. Is there a way in which i can poll all 300-400 points in one go. I know this is possible with a modbus polling software but i am after the graphical content for the customers benefit.

Thanks

Open Discussion / AdvancedHMI on Webpage

« on: March 30, 2015, 08:51:23 PM »

Not sure if this topic has come up before but does anybody know if its possible to setup AdvancedHMI on a webpage.

I have a few remote sites that i currently remotely log into from my PC via a VPN to monitor. AdvancedHMI works perfectly over this system but i would like to drop the VPN and also make the SCADA screens available via a webpage to my other employees.

I am sure that with a bit of porting on the modem i can achieve using advancedhmi without the VPN but I can help but think how awesome it would be just to have it on a webpage that is viewable on both a PC or a Smartphone.

Although my Visual Studio skills are not awesome i am willing to help with any development i can should people be interested in getting something like this going.

Support Questions / DF1COM Problems

« on: March 16, 2015, 10:01:03 PM »

Hi,

I have a micrologix 1500 connected via df1 serial to my pc which is using a USB to serial converter. I can connect to the PLC and have a great HMI running. However after a certain amount of time (not always the same) it hangs. I have tried two different USB to Serial converters and numerous configurations of baud rate etc. Am i missing something here??
