Setting Up the Gateway Unit

(1) Setting the Gateway Unit mode

Since the actuators are operated in the position-number specification mode, set each position of the
mode setting switch (SW1) as follows:
1: OFF 2: ON 3: OFF 4: OFF

(2) Setting the node address and baud rate for the Gateway Unit

Node address = 0
Baud rate = 500 kbps (example)
To effect the above settings, set the DIP switches as follows:
DR1: ON DR2: OFF
NA1, 2, 4, 8, 16, 32: All OFF


9.5

Setting Up the DeviceNet Master Unit (CJ1W-DRM21)

(1) Setting the unit number

On the PLC, set “0” indicating a CPU high-function unit.

(2) Setting the node address

Set the master unit’s node address on the network to “63” to prevent duplication with other slaves
within the range of 0 to 63.

(3) Setting the baud rate, etc.

The baud rate is set to 500 kbps. Accordingly, set the DIP switches as follows:
1: OFF 2: ON 3: OFF 4: OFF
* For details, refer to the operation manual for your PLC.


9.6

Assigning the Master PLC Address

Each slave (gateway unit) must be assigned to an I/O memory area of the CPU unit in which the
master unit is installed.
This assignment is performed either by free assignment where the DeviceNet configurator is used to
automatically assign an I/O memory area, or by fixed assignment using CX-Programmer. (Refer to
8.4 and 8.5.)
