ET24XX Drivers Configure OP Running Program Parameters Error

[bkawa]

Does anyone have experience with the Eurotherm et24xx LabVIEW drivers from the NI site? Link below:

I'm utilizing these for control of some Eurotherm 2416 temperature controllers via RS-232, with the intent of choosing and running pre-loaded thermal programs from LabVIEW.

The drivers work fine for the most part, though I'm receiving a VISA Read timeout expired error when using the ET24XX Configure OP Running Program Parameters VI. I'm assuming this VI is used to choose which thermal program (max 4 programs set on the controller via Eurotherm's iTools software) to execute when the Program Status is set to Run afterwards, though other than the context help, there are no programming manuals associated with these drivers.

I attached my test code. The VISA Read timeout expired error only occurs at the Configure OP Running Program Parameters VI, despite many of the other et24xx VIs utilizing VISA Read at some level. I have also tried putting the controller into Configuration Mode via the Set Instrument Mode VI prior to attempting to choose the running program, with the same resulting error.

I may be misinterpreting the purpose of this VI, and it is not actually possible to choose a program to run with these drivers. Some insight would be appreciated.

Thanks!
