7.1 Parameters
Node ID
In the network, each device has a Node ID that is
used to address the device and to define the priority
(default: 25d; 19h)�
Baud rate
Baud rate setting
125 kbaud, 250 kbaud or 500 kbaud
(default: 250 kbaud)
Preset value
The preset parameter is used to predefine a position
value that is to be reached at a specific physical
position�
Terminating resistor
The 120 Ω termination resistor can be activated
using the software
(default: deactivated)�
Direction
The counting direction is adjustable�
Cycle time
The cycle time is adjustable�
