13.4 Constructing PROFIBUS-DP Network by Using
AH10PFBS-5A
13.4.1 PROFIBUS-DP Network Figure
AH10PFBS-5A is used for connecting the AH500 series CPU module to the PROFIBUS-DP
network.
See the following illustration.
13.4.2 Terminal Resistors
When two AHRTU-PFBS-5A are installed at the two ends of the network respectively, their
PROFIBUS communication ports need connect the terminal resistors (One resistor contains three
small resistors, Rt, Ru and Rd as follows.) One standard PROFIBUS connector possesses a built-
in terminal resistor and the resistor can be connected or not via the switch. User can purchase the
PROFIBUS connector to add the terminal resistor.
