Output data buffer
The output data buffer refers to the area where parameters sent from the DeviceNet
master node to the LK-DN100 are stored.
A word is 16 bits.
Input control buffer
The input control buffer refers to the area where LK-DN100 statuses and responses to the
output control buffer control signals are stored.
