I'm designing a system with a ControlLogix L61 PLC monitoring 16 Point I/O racks using EtherNet/IP over a switched Ethernet network. I also have to pass data between the ControlLogix PLC and another SCADA system using Modbus TCP.
I've used the Red Lion G3 before and liked it a lot - I thought it would be an excellent fit for this job, both as an HMI and a protocol converter. However, we have run into a problem - we copy the data we receive from the Point I/O modules into an array of user-defined structures, to enable us to run the same PLC code against every machine's data. Using the G3's Allen Bradley Native Tag Addressing it does not seem to be possible to read data in arrays of user-defined structures, either by importing the .CSV file from RSLogix 5000 or by entering them directly.
Is there any way round this problem? If not, has anyone implemented this kind of job using a C-more panel?
