Use Global Address Map (Unallocated registers will be zero) Reset on Change #100
Description
Setup -> Extended -> Modbus Definitions
Use Global Address Map (Unallocated registers will be zero) resets whenever Start Address or Length is changed. When this happens, it seems like the unallocated registers are reset to null instead of 0. Going back into Modbus Definitions and hitting OK again on the setting will provide a temporary fix until Address or Length is changed again (unsure if any other setting changes trigger the reset).
