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 shown 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 communication
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 communicated.
