The operation mode is set using a parameter. Set the mode selector switch on the front panel of the controller to the MANU position, and set parameter No. 84,

“FMOD: Fieldbus operation mode” using the RC PC software (V6.00.05.00 or later). (Refer to 2.10, “DeviceNet Parameters.”)

2.6 Setting the Node Address

The node address is set using a parameter.

Set parameter No. 85, “NADR: Fieldbus node address” using the RC PC software. (Refer to 2.10, “DeviceNet Parameters.”)

Allowable setting range: 0 to 63 (The parameter has been set to “63” at the factory.)

(Note) Exercise caution to avoid node address duplication.

The nodes (controllers) are assigned in the order of their node address in the remote I/O address areas of

the PLC. (This is when the mount assignment mode is selected. A different rule applies when a

configurator is used.)

For details, refer to the operation manuals of the master unit and PLC installed in the master unit.

(Note) The baud rate is automatically set to the same value as the baud rate set in the master. Accordingly, you

need not set the baud rate.

(Note) After you have set the parameter, reconnect the controller power and return the mode selector switch on

the front panel of the controller to the AUTO position. If the switch remains in the MANU position,

operation by the PLC cannot be performed.

2.7.2 Remote I/O Mode (Number of Occupied Channel: 1)

In this mode, the actuator is operated by specifying position numbers, just like you do when PIOs (24-V I/Os) are used. Set position data using the RC PC software or teaching pendant. The number of available positions is determined by the setting of parameter No. 25, “PIO pattern.” The I/O specifications for each PIO pattern are shown below. (For details, refer to the operation manual for the controller.)

Value set in

parameter No. 25

0 Positioning mode 64 positioning points and two zone output points are available. 1 Teaching mode 64 positioning points and one zone output point is available.

2 256-point mode 256 positioning points and one zone output point is available. 3 512-point mode 512 positioning points are available. There are no zone outputs.

2. ACON-C/CG, PCON-C/CG

4 Solenoid mode 1 7 positioning points and two zone output points are available.

5 Solenoid mode 2 3 positioning points and two zone output points are available.

Operation mode I/O specification

Positioning operation and jog operation are supported. The current position can be written to a specified position.

A direct operation command can be issued for each position number. A position complete signal is output for each position number.

The actuator is operated by specifying forward, backward and intermediate position commands. A position complete signal is output separately for the front end, rear end and intermediate position.

The key ROBO Cylinder functions that can be controlled in this mode are summarized in the table below.
