conditions *1 and *2.
Maximum Capacity of Data Register 1) When the number of coils and relays is the default value, the following
condition must be met:
(Number of holding register words) + (Number of constant register words) +
(Number of link register words) ≤ 25,998
2) The maximum value of each reference can be freely set within the above limit
and the following ranges using MEMOSOFT.
