IAI电缸控制器PCON-CA的PROFIBUS通讯笔记

以下来自MJ0258手册，对PCON-CA的PROFIBUS-DP通讯的操作说明：

Operation Modes and Functions

PCON-CA/CFA controllers supporting PROFIBUS-DP can be operated in a desired operation mode selected from the following five modes.

Operation Modes and Key Functions

[3] Half direct mode: In this mode, the actuator is operated by specifying the speed,

acceleration/deceleration and push current, in addition to the target position, directly as values. Number of occupied bytes: 16 bytes (8 words)

[4] Full direct mode: In this mode, the actuator is operated by specifying all values relating to position control(target position, speed, acceleration/deceleration, etc.) directly as values.Number of occupied bytes: 32 bytes (16 words)

4.3 PROFIBUS-DP (Slave Station) Settings

(1) Name of each part

The name of each part relating to PROFIBUS-DP is shown.

(4) Operation mode selection (setting) 第95页

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.

(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.

(6) Status LED indications

The board operating condition and network condition can be checked using the two LEDs provided on the front side of the controller.

(Note 1) After the necessary parameters have been set, reconnect the controller power and return the mode selector switch on the front side of the controller to the AUTO position. If the switch remains in the MANU position, PLC operation cannot be performed.

(Note 2) 有关波特率的设置The baud rate is automatically set according to the corresponding setting on the master side and thus need not be set.

The address assignments under each operation mode are shown below.

PLC output →PCON-CA/CFA input (* n indicates the initial output address for each axis.)

(Note) The “occupied area” is occupied according to the operation mode setting.This area cannot be used for any other purpose. Also pay attention to use of duplicate addresses.
