Device are recogniced but there are no function blocks

[tomas]

I�m using the NI configurator. I have a Fp-3000 controller a E+H Micro pilot (level meter) and a E+H Cerabar (pressure meter). The system was working fine until I have connected a Mass Flow meter. Suddenly the pressure meter disappears and the system sends an error message. After that I have disconnect the mass flow meter to restore the original configuration but when I try again the system couldn�t detect the function blocks from the pressure meter. It just detects the device but no function blocks appear. I have tried to reinstall the software but nothing helped. I have used the last DD from the internet. When I use the NI FBus Dialog and expand the root it detects the device but no function block appears. I thin
k that the DD are not detected in the right way.

Can you double-click the device missing function blocks to check whether the device has a fixed address (0x10 to 0xf7), I doubt your device had a default address (0xf8 to 0xfa), which would cause such missing function blocks problem.

Which version of NI-FBUS Configurator are you using now? If it is version 2.3.6 and your device hadn't obtain a fixed address, you might need to adjust network parameter T1, T3 and Slot Time in the Interface Configuration Utility ("Advanced" button of the interface port like "port0"), please try to change the value to T1 = 0x40000, T3 = 0x30000, Slot Time = 6 and restart NI-FBUS Communications Manager and Configurator software again, see whether it helps.

The device address is 247 (0xf7)and all the parameters are like you told me

[Fbus]

OK, 0xF7 is a fixed address, so please ignore the default address issue I mentioned before.

You said there's no any block in this device, even no resource block? I suggest you right-click this device and choose "Set to factory default" to reset this device, see whether it helps.

On the other hand, you can also set a lower address (like 0x1A, 0x20) to this device, and have a power cycle on this device.

Hope it helps.

After a lot of tries I found that I can recover the function blocks changing the device address.
