5.4 Special Data Registers Specific for TP Series
The types and functions of special data registers (special D) for TP04P-20EXL and TP70P-211LC1T are listed
in the table below. “X” in the column of Attibute refers to un
retentive and “O” refers to retentive (latched). “◎”
indicates you need to write “
H’5678” in D4600 to have the data written into Flash and then the data is retentive.
D4530-D4699 should work with M1666 and M1667 to read or write. When M1666 is ON, the data is read for once. When
M1667 is ON, the data is written for once.
