
Completion of reading: The master station finishes reading data form a slave station

Completion of writing: The master station finishes writing data into a slave station.
Additional remark:
If the reading of data and the writing of data are synchronous, the related flags will be controlled in the
ways described below.
The master station stops reading
data and writing data
simultaneously, or the master
station is reading data and writing
data simultaneously.
The master station finishes reading
data and writing data
simultaneously.
Timeout
The master station can not produce
a packet which will be sent.
The data sent by a slave station can
not be stored in the master station.
3. Description of the setting of the parameters related to a PLC Link:
The setting of the parameters related to a PLC Link is described below. (Suppose the master station and
slave station 1 are AHCPU530-EN.) The data in the device addresses starting from D100 in slave station 1
is read into the device address starting from D9 in the master station. The number of data read from slave
station 1 is 10. The data in the device addresses starting from Y0.0 in the master station is written into the
device addresses starting from Y2.0 in slave station 1. The number of written into slave station 1 is 5. The
slave station type is AHCPU530-EN (16#E001). The slave station address is 16#0001.

Additional remark:
There are a variety of Delta PLCs. Users can construct a PLC Link by connecting AH500 series CPU
modules to DVP series PLCs, and other models. Consequently, there are limitations on the devices which
can be used, the data exchange which can be performed, and the number of data which can be
exchanged.
