MB300 Communication between AC800M and AC410 with CI855
I would like to send and receive data from an AC410 to a AC800M.
We already use the solution with OPC property transfer but now we would like to get more datas.
I have already a CI855 installed on my AC800M. But I Have few experience with ABB controller and I would like to know what I have to do to get the information from the AC400.
I learn in the documentation that we can use some functions blocks likes MB300Connect, MB3000DataSSend in the AC800M but I don't really know what I Have to do in the AC400
An example should be very interesting for me
Thanks in advance
The information on how to configure the Dataset elements on the AC410 controller is in the AC400 series DB Element reference manuals. Each DS element can transfer 24 * 32Bit Words, ( Real, Int, IntL or Boolean).
For each dataset in the AC410 there is one corresponding DataSet in the AC800M. The AC800M commands you mention control the connection and read/write of this data in the AC800, everything is handled automatically by the system software in the AC410.
If you have worked with "On Line Builder" on an AC400 controller before then creating "Data Sets" is normally very easy.
If you have never worked with on-line builder, its probably best to get someone else who is familiar with the command line interface of this tool to assist. Some complications can arise if there is not enough memory space to create DS elements in the AC410, and this is not a job for beginners to fix.
