When setting the DIP switches, turn off the power supply of the PLC and disconnect the module from the
network. The setting isn't reflected until the module is reset.
Set the baud rate in such a way that all the devices on the network communicate at the same speed.
Set the node addresses for the other devices in such a way that they do not overlap.

Setting of Output Status
The output status is set by the DIP switches on the side of the module.
This status specifies whether to clear or hold the output data to the output module in case of a communication
error or when the EH-CPU stops.
Bits 1, 2, and 3 are reserved by the system. They must always be set to OFF.
