to issue Cresnet IDs 03 to FE, ultimately doubling the number of devices in the
network.
Slave control systems with Ethernet and Cresnet abilities can only be configured to
operate as an Ethernet slave.
The 3-series can only be an Ethernet slave to another 3-series controller, no Cresnet
slaving is supported. A 2-series can be a Cresnet or Ethernet slave to a 3-series.
Refer to the following table for reference.
NOTE: There can only be a single master IP table entry.

Differences from the 2-Series Control Systems
• Adding a Master IP Table using the ADDMaster command does not
require a reboot.
• Removing a Master IP Table entry using the REMMaster command does
not require a reboot.
• The prompt on the 3-Series Control System never changes.
• Use the MIPTable command to get the master IP Table entry.
• There is a new command which indicates the slave status.
• New commands to configure the slave behavior.
Functional Behavior
A 3-Series Control System can switch back and forth between the slave mode and
normal mode (running registered user programs) without requiring a reboot. There
are certain parameters that determine how long the slave controller tries to connect to
the master before reverting back to the regular mode.
Assuming No Master IP Table Entry When Booting the
System
• Adding a Master IP table entry enables the slave to start connecting to the
master. Once the slave is connected all user programs stop executing and
the device enters into the slave mode.
• Stopping the program on the master does not force the slave back into the
regular mode. The slave tries to connect for the period based on the
configuration parameters before reverting back to the regular mode. Once
this happens, the slave controller does not go back into the slave mode until
the control system reboots or the master IP Table entry is added again. An
error gets logged indicating this condition
