(3) Bus terminal processing
If the connector is to be connected to the network terminal node, connect the terminal resistor to the
PROFIBUS-DP communication connector as shown below or use a connector with terminal resistor.

(4) Operation mode selection (setting)
Set a desired operation mode using a parameter.
Set the mode selector switch on the front side of the controller to the MANU position, and then set parameter No.
84, “FMOD: Fieldbus operation mode” using the RC PC software (V6.00.05.00 or later). (Refer to 4.7,
“PROFIBUS-DP.”)
Note
Refer to operation manual of RC PC Software for the applicable version.
Set value Operation mode
Number of
occupied bytes
0 (factory setting) Remote I/O mode 2
1 Position/simple direct mode 8
2 Half direct mode 16
3 Full direct mode 32
4 Remote I/O mode 2 12
* If a greater value is entered, an excessive input error will occur.
(5) Node address setting (Refer to 4.7)
Set the node address using a parameter.
Set parameter No. 85, “NADR: Fieldbus node address” using the RC PC software.(Refer to 4.7, “PROFIBUS-DP
Parameters.”)
Settable range: 0 to 125 (The parameter has been set to 1 at the factory.)
(Note 1) Pay attention to duplicate node address settings.
(Note 2) PROFIBUS-DP node addresses are set with the master station always having address 0. Accordingly,
addresses of slave stations can be set between 1 and 125.
