Writing Data with the WRITE DATA Bit Section 5-2
5-2-1 Outline
The following example of positioning sequences summarizes how to write
data to the PCU.
When the WRITE DATA Bit (word n+1, bit 12) in the operating memory area is
turned ON, data in the PLC’s DM or EM Area is written to consecutive
addresses in the PCU according to the number of write words, the write
source area, the write source word, and the write destination address desig-
nated in the operating data area.
The “n” in the CIO Area is the beginning word of the operation memory area
and is determined when the unit number is specified.
The “m” in the DM Area is the beginning word of the common parameter area
and is determined when the unit number is specified.
The “I” in the EM or DM Area is the beginning word of the operating data area
specified by the common parameters and is also the beginning word of the
operating data that determines data transfer.
With data writing, 772 words of data in consecutive addresses can be sent at
once.
