SP7 toolkit and S7300 error 66

[E.S.Mike]

Hello everyone,

We are trying to comunicate with the s7-300 (indicated below ). When we try to run the example "exmpl write_bit_array_in_DB.vi" an error 66 show up.
We comunicate correctly to the PLC and we are capable of make a "ping" from labview (with another example from labview).

We are wondering if it might be a configuration issue on the S7/300 that we are missing or maybe it is not possible comunicate with our hardware (CPU315-2DP+CP 343-Lean).

Thanks. 😉

Hi,

i already answered you by e-mail.

For everyone else: For a S7-300 CPU leave Rack & Slot in "SP7 connect" on its default values 0 and 2 respectively.

Hello,

We started a new .vi (almost the same as the example) with the parameters and worked perfectly.

Thanks a lot.
