Siemens PLC -> NCU comms 840DSL

[JasonWade]

Hi

I have a Siemens 840Dsl system and need to write some large arrays of data from the PLC Data Blocks to the NC (GUD data I think?). Can anybody point me in the right direction for this?

(If it's relevant to the question I have 4 arrays, all 1000 elements, 2 are REAL type and 2 are INT type. I could reduce the size of the arrays if it helps, but not below 200 elements)

Thanks
