Like Chris , I also Just wanted to add my experiences for the benefit of others.
I had a similar problem, and desolved it exactly like Cheris.
But I still have an Undissolve issue with FP-AI-V100m dualpoint in FP-2015 system.
My system works 24/365 (non-stop), somtime for monthes with no problems. Then I find that the FP-2015 is not working, and all it's leds are off, although the power supplay is OK (24vdc). After a power reset the system will continue working fine for some days/hours, but then it will fell down again, and so on..
I replaced the TB-10 (type D), the FP-2015, the Power supplay, but the issue have not "stop" until I replaced the PF-AI-V100m. Not really stop, but give me some more monthes of silence.
I test the voltage of the Oxygen sensor (only 1 is connected to that DualPoint), and it is in the range ot 0-100mv.
I replaced the FP-AI-V100m already twice, the "bad" DualPoint caused the same problem when it is connected to a different Controler.
I have a second system, with a same configuration, and have no problems their ..
After more than a year of problems, reading also other's problems in this forum,
I'm changing sensors and TB-10 to FP-AI-110, with a hope that it will be more stable.
My configuration is:
FP-2015, TB-10 (FP-RTD-PT100 in slot 1, FP-AI-v100m in slot 2), FP-DI-301, FP-DO-420 *2 modules.
I use 2 24vdc power suppliers, each with 2 separate V.out for the different modules.
