Introduction
Conditions of use
PLC:
- CP1H + CP1W-CIF01 + CP1W-CIF11/12
- CP1L-M + CP1W-CIF01 + CP1W-CIF11/12
- CS1/CJx + CJ1W-SCU21-V1
- CS1/CJx + CJ1W-SCU41-V1
Principle
NS Terminal is connected to a PLC (serial port A or B). The SAP uses FINS command to send request which are converted to Modbus RTU using the Gateway functionality of the PLC serial port:
The MX2 SAP can:
- Control the output frequency
- Control de output current
- Status (Run forward/reverse)
- Read/write parameter via Modbus MX2 addresses
- Backup 850 parameters into a CF card (except Modbus comm parameters)
- Restore these parameters into the MX2
Configuration
Once the SAP has been draged & droped on the page, a double-click will display the windows to setup the communication. Attention, this operation should be executed only once. In case of error, suppress the SAP and drag & Drop again a new instance.
Then specify the port n° according to the following table:
Unit CJ1-SCU:
PLC configuration
The PLC serial port should be configured in Serial Gateway mode:
Reduce the response timeout to an appropriate value. A value less than 1 second would be better until the SAP timer is cycling at 1 second
NS configuration
MX2 communication configuration
These parameters are set manually using the keypad device to enable the Modbus communication with the PLC:
WARNING: MX2 should be restarted after any changes !!
Backup/restore Functionality
This option accessible with the + button, allow to Save/Restore in/from a CF card, following parameters:
Access could be protected using the command button not visible with a macro to disable its input
