G(P).RDMSG instruction
Use this instruction when executing slave module parameter access.
Applicable devices
*1 Bit specification of word device can be used for bit data.
A bit in a word device can be specified by "Word device.Bit number". (Specify a bit number in hexadecimal.)
For example, bit 10 of D0 is specified as D0.A.
Note that the bit specification cannot be performed for timer (T), retentive timer (ST), or counter (C).
Setting data
