Hello,
I am trying to run the Watlow F4 Controller Driver downloaded from NI website to control an environmental chamber. I connected the GPIB port to PC using a GPIB-USB-HS cable. The GPIB to ModBUS interface board ICS 4804A is found in MAX and I am able to get queries from it with *IDN? command. When I run the Watlow VI. I got Error -1073807331 (0xBFFF001D) The Specified attribute is not defined or supported by the referenced resource. I am not sure what I am missing. Please see attached picture for details. Any suggestions are greatly appreciated.
Many many thanks
Fliu
