PROFIBUS-DPbus topology
It is necessary to connect a matching terminal resistor to the end of PROFIBUS bus
and set DIP switch properly. The system PEs must be reliably grounded.
Length of communication cable between GT60DP2 and PROFIBUS-DP master varies
with different setting of baud rate of the master. Restrict communication cable lead
length strictly according to the Siemens DB9 standard. The following table describes
requirements on baud rate and communication cable lead length.
