Smartlink Modbus A9XMSB11
Environment
A9XMSB11 + EcoStruxure Power Commission
Issue
Smartlink Modbus firmware upgrade failed each time with EcoStruxure Power Commission.
Cause of Issue
There is a known gap when you upgrade the FW with a Serial Link speed of 9600 Bauds.
Prevention
Ensure that your serial link speed is higher than 9600 Bds.
Resolution
To change the Serial Link speed of your Smartlink, you need to perform a Factory Reset.
To reset the Acti 9 Smartlink factory settings (pulse weight at value 10, meters at 0, communication
parameters), proceed as follows:
- De-energize Acti 9 Smartlink
- Set the Modbus address to value 00
- Re-energize Acti 9 Smartlink
- Set the selected address
Automatic adaptation to the communication parameters only occurs on powering up the Acti 9 Smartlink. After receiving a maximum of 25 frames from the master, Acti 9 Smartlink automatically adapts its communication parameters to those of the master (speed, parity and number of stop bits).
