I/O Communication

The device map varies depending on the operating mode of the DL-DN1. Select an operating

mode suited for the functions of the sensor amplifiers to be used, before accessing each device.

The memory in the DeviceNet master unit is linked to the buffer memory in the DL-

DN1 as s hown below.

Select the DL-DN1 operating mode to suit the functions of the sensor amplifiers to be used.

The DeviceNet device configuration and the data available for I/O communica tion

vary, depending on the selected operating mode of the DL-DN1 and the number of

connected sensor amplifiers. An appropriate operating mode should be determined

by considering the memory occupied and the data that can be co

mmunicate
