When multiple POD are connected to a link unit of PLC, use the terminal converter (UG00P-TC), the
optional equipment made by Fuji Electric. Co., Ltd. for RS-485 connection.
•
Set the dip switch (SW1) of UG00P-TC as 2-wire connection when the UG00P-TC terminal converter is used.
•
Short-circuit between +RD and +SD, and -RD and -SD when the UG00P-TC terminal converter is not used.
When multiple POD are connected directly to MITSUBISHI’s QnA CPU port, the optional equipment,
UG00P-DI is required. Also, the use of the optional cable, MB-CPUQT which is to connect UG00P-TC on
POD side to UG00P-DI on QnA CPU port side, is recommended.
•
Set the dip switch (SW1) of UG00P-TC as 2-wire connection when the UG00P-TC terminal converter is used.
•
Short-circuit between +RD and +SD, and -RD and -SD when the UG00P-TC terminal converter is not used.
