5. Flow and Commands of Basic MECHATROLINK Communication

(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.
z Example of connector with terminal resistor: SUBCON-PLUS-PROFIB/AX/SC (Phoenix Contact)
z Connecting the 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 (V8.00.00.00 or later).
(Refer to 5.7, “PROFIBUS-DP Parameters.”)
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
5 Position/simple direct mode 2 8
6 Half direct mode 3 16
7 Remote I/O mode 3 12
8 Half direct mode 3 16
* If a greater value is entered, an excessive input error will occur.
(5) Node address setting
Set the node address using a parameter.
Set parameter No. 85, “NADR: Fieldbus node address” using the RC PC software.
(Refer to 5.7, “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.
