Receive Data Word Allocation (3rd Operand of PMCR)

None.

Note 1. The following settings must be made together with this sequence; they cannot be set separately. Lower limit, upper limit

Reference value, data output timer

Data output conditions, scheduled print timer

2.The limit value and reference value can be set to 3 digits for the integer portion and to 4 digits for the decimal portion.
