Each TD device functions as a network master when it is connected over a network that
contains one or more S7-200 CPUs. The TD device is also designed to operate with other
masters in a network. Multiple TD devices can be used with one or more S7-200 CPUs
connected to the same network. More than one TD device can connect to the same S7-200
CPU.
