(3) Connection Example 3: In the case of the link connection through the gateway unit:
In the case that the 0V line for the power to each controller can not be shared, or the
DC24V type controllers are used together with the AC100/200V controllers, the power
source can be separated for each controller as shown in the figure.
Because the power to the primary circuit inside the SIO isolator is supplied from CN1, make
sure to connect CN1.
(4) Connection Example 4: In the case that the PC is connected while the positive side of the
24V power is grounded:
Inside the most PCs, the GND (0V) line for the communication is short-circuited to FG
(frame ground), when the PC is connected, a short-circuit occurs in the 24V power line
which might cause the PC breakdown. In such case, connect the controller (including the
gateway and ROBONET) using the SIO isolator and USB conversion adaptor
(RCB-CV-USB) as shown in the figure.
1. The RS232C conversion unit RCB-CV-MW (attachment to the PC application software
RCM-101-MW) can not be used for the connection between the PC and SIO isolator.
2. Connect the external machine communication cable (3) to CN1 for the SIO isolator.
