Support Questions / Re: Modbus On 30000 and 40000 ranges
« on: March 17, 2016, 04:54:35 PM »
acutally i believe it has something to do with the offset..
on the inputs there is an offset of 1.

I have tried this solution but the value does not update.. It works with any value above 30002 but just not the first for some reason.
Thanks

Hi,
I seem to be unable to get values from registers 30000 and 40000 through advancedhmi.. I can get the values when i use Modbus Poll but it seems to hang when using advnacedhmi..
anyone else with same problem

Hi Archie,
I am having more trouble with these datasubribers. what i want to do is increase the speed of the modbus reading from a Siemens S7-414. I am reading roughly 400 points from it and it seems to do one at a time and is very very slow. Is there a way that a datasubscriber will fix this. If so can you provide a sample code. I apoligize for my stupidity but i just cant get my head around this one.

Hi Archie,
Thanks for the code..
It is close but basically what i need is the following.
When Bit 0 is true it adds 1 to the variable
When Bit 1 is true it adds 2 to the variable
When Bit 2 is true it adds 4 to the variable
When Bit 3 is true it adds 8 to the variable
When Bit 4 is true it adds 16 to the variable
When Bit 5 is true it adds 32 to the variable
When Bit 6 is true it adds 64 to the variable
When Bit 7 is true it adds 128 to the variable
When Bit 8 is true it adds 256 to the variable
When Bit 9 is true it adds 512 to the variable
When Bit 10 is true it adds 1024 to the variable
When Bit 11 is true it adds 2048 to the variable
total value of bits adds up to 4096 @ 100%
Hope this makes sense

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??

I am totally confused as to how to use a datasubscriber to get more than one modbusTCP value.. Is there Tutorial or explaination somewhere??

definitely not using datasubscribers and its still very slow. could it be lag in the PLC??

Hi Archie,
Thanks for the info. Fixed up half of my problem. It seems as though now once it grabs the modbus data it illiterates through each individual item to change the status of it. There is about 3-4 second delay. Is there any other values you can think of that can be change to minimize this time further??
Thanks

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
