Based on these values shown above, a good place for the MODBUS PORT X
COMMAND ERROR POINTER is address 1500, as shown.
With the COMMAND ERROR POINTER set to address 1500, this will place your
Command Error Data at addresses starting at 1500 of the module memory, and
because of the before mentioned configuration of the BACKPLANE
CONFIGURATION READ REGISTER START and READ REGISTER COUNT parameters,
the command error data will be placed into the tags beginning at
MCMR.DATA.READDATA[500].

register within the READDATA array. For a command list consisting of 100
commands, the following table is true.
