Reading Ext.Data Registers in Mitsubishi PLCs

Hello,
Will the Protocol format 1 or 4 support reading of ER (extended data registers) in Mitsubishi PLCs?

Which protocol i have to implement to read/write to ER device type of Mitsubishi PLCs?

I could not get this information in any websites.

Thanks in advance.

Hello All,
I could get the answer myself by reading Q series PLC manuals. ER stands for Extended File Registers. It can be supported by Mitsubishi format 1 or 4 protocol.

Still to implement it with many device address ranges.

Hello All,
I am still facing problems reading Extended file registers using protocol format 4. This protocol do not have any command for reading ER device types in FX-3U OR FX-3G PLCs. How do I read ER using protocol format 4? OR do I need to implemented different protocol?

thanks in advance.
