Modiconn 185-102 Input Card

Has anyone ever had the Modicon 185-102 Input card give a 32767 value to a 3XXXX register?? The manuals say the input is 0-4096 and clamps at 4200 counts........ This is an existing card that has been working fine for years. But now the 3XXXX number will not work in the program since most blocks can only use 0-9999. All channels are this way. Any help would be appreciated!!!
