0 Standard Modes
Requests the master to operate in Configuration / Protected
Mode, depending on the position of the MOD switch.
1 Setup Mode
To enter Setup Mode, set this bit to 1, i.e. set the least

Setup Mode. If the MOD switch is ON, the Unit will remain in
Protected Mode.
Check the Mode Flag in the Response area to see if the

for slaves 1 to 5.
