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.
*1
It is possible to read instantaneous flow rate or rewrite setting value regardless
of the detection mode setting.
*2
This is not available with the FD-MH series.
Output data
Data here will be
reflected in the master unit.
Input data
Data here has been
output from the master unit.
