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
