TURCK picofast PSG 3-2 Cable for PROFIBUS-DP System
PROFIBUS-DP is an industrial network protocol that connects field I/O devices in order to
eliminate hard wiring. The network connection increases device-level diagnostic capabilities,
while also providing high-speed communication between devices. PROFIBUS-DP is based
on the RS-485 serial data transfer standard. In most cases, the termination and physical media
rules for PROFIBUS-DP are the same as those required for RS-485 communication. A
PROFIBUS-DP network supports up to 126 nodes and virtually an unlimited amount of I/O.
The bus uses a trunkline/dropline topology. Power and communication are provided via
separate cables, allowing easy segmentation of the power structure to avoid overloading.
PROFIBUS-DP is capable of running at data rates as high as 12 Mbaud. When used at high
data rates, the cable drop length from the trunk to a node is severely limited. For example,
when used at 12 Mbaud, nodes must be directly connected to the trunk, with no drop length allowed.
