Chapter 3 PLC System Configuration & Settings Input AH5x0-EN series read data from a remote device. Local Start Address: The start address of D data registers where AH5x0-EN series store data Remote Start Address: Device type and start address of the remote device to be read Quantity: Data length of input Output AH5x0-EN series write data to a remote device. Local Start Address: The start address of D device type of the source data of AH5x0-EN series Remote Start Address: Device type and start address of the remote device to be written Quantity:
Data length of output While the data exchange setup for AH5x0-EN series is conducted, the local device can only be the data register D with Word as the unit. And remote address can take Bit as the unit which may not start from 0, such as D0.3 as a remote start address. If the set data size is not a multiple of Word, the local devices will still make the data exchange via corresponding bits and the bits which are not in data exchange will keep original state. For example, if the data in remote M0~M19 is read to local data register D0~D1, the data will be stored in D0.0~D1.3 in order and D1.4~D1.15 will keep their original states. 3-189
