the terminal resistor at the end
of the SIO communication line.

In a DeviceNet network, a
terminal resistor must be
connected on both ends of a
main line. Check the operation
manual for the master (PLC).
*1 The gateway unit does not come with a terminal resistor.
Use a terminal-block type terminal resistor (121
Ω ±1%, 1/4W) or T-branch tap with terminal resistor (121 Ω ± 1%, 1/4W) by Omron, or
connect other resistor of the same specification directly between the white and blue terminals on the communication connector.
