8.7.2.2 Configuring a Base Module as a Slave

The TL891/TL892 base modules are shipped configured as standalone systems. When they are used in conjunction with the TL890 DLT MiniLibrary expansion unit, the expansion unit must control the robotics of each of the base modules. Therefore, the base modules must be configured as a slave to the expansion unit.

After the hardware and cables are installed, but before you power up the expansion unit in a MiniLibrary system for the first time, you must reconfigure each of the base modules in the system as a slave. The expansion
