Directsoft 5.2 with Siemens TI335-37

[ratheret]

Hi,

Can anybody help me figure out why I can't write my program changes to a Siemens TI335-37 CPU. I have it in 'Program' mode (no switch on this model), Link is established (I can download the program from the PLC for editing), but when I try and save the new code back to the CPU, I get a Memory Write error with the Link Status showing 'No Response from PLC'.

I haven't worked with this model CPU before and have no documentation. Are there links or something else internally on the CPU that need changing?

Thanks,

Dave
