5.3.14 Configuring the Controller as a Modbus Master
The LP6000 controller can monitor and control other Liqui-tect units in a "master/slave" configuration
using Modbus communication. Other Liqui-tect panels can be connected and their status and alarms
viewed through the "master" controller.
Setting up a Master/Slave system requires two steps. Connecting the slave units to the master unit, then
configuring the Modbus communication settings for each device depending on type of connection:
• Connecting to the EIA-485 Port on page 50.
• Connecting to the Ethernet Ports on page 51.
