4-1-3 G730 Remote Terminal Allocation
Slave Address Allocation Using one Master and two Expansion Masters in one system allows the connec-
tion of up to 28 Slaves (G730 Remote Terminals).
Use the DIP switch to set the Slave address for each Slave to a value from #0 to
#27. Addresses #24 to #27 cannot be set for 4-point Slaves. The Master and
Expansion Masters recognize the controlled Slave by the Slave address.
