TCP connection to Eaton E4 PLC

I am using a Easy e4 PLC on a small project and trying to use matlab to monitor an analog signal on channel1 (AI(1))

If I am in a web browser I can type in; xxx.xxx.xxx.xxx/api/get/data? elm=AI(1)

where xxx.xxx.xxx.xxx is the ip address

and I get a return like {"OPERANDS":{"AISINGLE":[{ "INDEX":1,"V":813}]}}

I have tried using Matlab read, write, and line read and write but no luck

Does anyone know how I might code this?

Thank you

Dan
