Block 9956: Pass-through Formatted Block for Functions 6 and 16 with Word
Data Block

If one or more of the slave ports on the module are configured for formatted
pass-through mode, the module sends input image blocks with identification
codes of 9956, 9957, 9958 or 9959 to the processor for each write command
received. Any incoming Modbus Function 5, 6, 15 or 16 command is passed from
the port to the processor using a block identification number that identifies the
Function Code received in the incoming command.
