Connecting FP module. I get the module in MAX, but cannot seem to read from this module

[thomasho]

Hi,

I'm kind of new to LV and was trying to change out an old computer with Win98 to a new one with XP. The program should be communicating with a FP-1000 (+FP-TC-120 and FP-TB-x) through serial ports. It finds the data with MAX and can read them there. But when the program, which is configured as the old one (only changed the serial port numbers), tries to read, it cannot do so.

It should be noted that the program manages to write through a serial port to a eurotherm controller, but not read from this as well.

Errors are:

VISA Read: 0xBFFF0072

VISA Read: 0x3FFF0006, both are made in FP Read.

Why is this so? The errors are read out of NI Spy. I tried to configure the connection using NI-Serial Troubleshooting Wizard, but it can't find the hardware although MAX can.

Regards,

thomasho

Fixed it...

Much inspiration here:

and I see now that this was not a needed post.

The problem was basically that I changed the FP Read to FP Advice, and for some reason this worked... Don't ask me why...
