2 : Enabled via Modbus communication

 

 

 

With this register set to ‘0,’ only Bank 1 is used regardless of the settings at Register 801 or 4101.

 

 

 

With ‘1,’ Bank No. specified at Register 4101 is used.

 

 

 

With ‘2,’ Bank No. specified at Register 801 is used.

 

 

 

In actual applications, use Register 801 to switch Bank No. via Modbus communication by setting this register  

 

 

 

to ‘2.’  Register 4101 is not suitable for frequent switching during operation.
