George, I am in Shanghai and the reps here are little more than sales clerks Could you share a little more about what your rep told you? Did the VIs use TCP, VISA or some other primitive VI? Thanks!

I am upgrading a 3 axis stepper system from parkers 6000 (ISA bus) to their 6k (RS232/Ethernet) indexer. I was wondering if anyone has suggestion or opinion about whether to write the communications vis from scratch or to buy the Viewpoint Motion Library. The application involves single PC to 6K connection uses scaling, limits, home, motion and status commands only, no I/O Much thanks

:worship: I tried each of the suggested methods, and they all work! -Using front Panel Datasocket connection to OPC, 1) write a True or False to boolean control (V3.1,3.2 in my example) 2) send 0 or 1 to I8 unsigned byte (V4.1,4.2, in my example) 3) convert 8 element 1D boolean array (with boolean array to number function) and pass to I8 unsigned byte. -In the block diagram 3)Use a datasocket write boolean subVi from dataskt.llb (V6 in my example). I had tried the boolean and I8 in the front panel DS connection before without success. My OPC server must have hosed up somehow on that occasion. Thanks everyone!

hi everyone I am working with datasocket and OPC server. The data comes in 2 forms, a 32 bit float and single bit. I can read and send the 32 bit tag by using the numeric data type single precision, but as for the single bit, the smallest numeric data type LV has is 1 byte. The OPC explorer program allows me to address the entire byte or each bit which represent valve on/off states. In LabView I just want to be able to address a particular bit, not the entire byte. Any suggestions would be greatly appreciated!
