Having exactly the same problem with a IO-DI8-TO8. expansion module. This is connected to a V130-33-RA22. Have a second flow meter connected to the V130 and I can store a zero value to the MI used with this HSC. However when I try and store a zero to the MI assigned to the expansion module HSC it reverts back to the previous value as discribed by Ziwi. Can anyone please help.
