
The limitation on data exchange performed by an AH500 series CPU module is described below.
Device Device range
Maximum length of data which
can be read/written
Relays M0~M8191
450 registers/100 registers
*
7200 contacts/1600 contacts
*
Data register D0~D65535
Link register L0~L65535
*. Maximum length of data which can be read/written (Reading data and writing data
synchronously)=Maximum length of data which can be read/written (Reading data and writing data
asynchronously). A PLC which is not an AH500 series CPU module can read/write the data in 100
registers at most, and the data in 1600 contacts at most.

If an AH500 series CPU module is a master station, DVP series PLCs can function as slave stations.
DVP series PLCs can read data and write data simultaneously.
