program by setting the drive and internal PLC program to two different station numbers. For
example, if user wants to set AC motor drive as station 1 and PLC as station 2, please write
following setting to the host controller:
When setting 01(Station) 03(Read) 0400(Address) 0001(1 data), the host controller can read the
Pr.04-00 from the AC motor drive.
When setting 02(Station) 03(Read) 0400(Address) 0001(1 data), host controller will read X0
data from the internal PLC program.
3. The internal PLC program will stop operation when upload/download programs.
