The host must be either a
PLC or PC. It is not
allowed to connect both at
the same time.

ERC3 power supply I/O cable
CB-ERC3P-PWBIO***
Note: The baud rate of an RC controller automatically
switches to 9600 [bps] if it detects a break (space) signal
lasting 150 [msec] or longer from the SIO port.
In some PCs, transmission lines are placed in break
condition when the communication port is not open. That if
such PCs are used, the baud rate of the connected RC
controllers may be set to 9600 [bps] unintentionally.
ERC3-SE
[Refer to Section 3.1 for connection of ERC2]
Caution Make sure to use the common 0 V line
of the 24 V power supply for each
controller (other than SCON).
For ROBONET connection, refer to the
separate ROBONET Operation
Manual.
