Outline of operation
● This instruction reads the parameters of the COM port of the unit, and stores them in the
area starting with [D].
● Specify the type of acquired data in [S].
■
Precautions for programming
● Describe the UNITSEL instruction immediately before the PMGET instruction, and specify
the slot and COM port numbers of the unit for which the parameters are acquired.
● The size of the area storing data varies in the range of 7 to 192 words according to the data
type specified in [S].
