Siemens profibus dp junction box.

From each coupler my profibus pa segment trunk will be chained trough junction boxes and from each junction box the spur lines will connect to the devices. My idea is to connect my s7 300 plc trough profibus dp to the dp pa couplers. Siemens continue to provide fms capability. With this general idea in mind i am asking the following questions.

Acromag series 900pb modules utilize the popular profibus dp fieldbus communication format. Profibus dp decentralised periphery profibus dp was developed from the basic fms technology as a low cost simple high. Profibus dp normally uses daisy chain connectivity as shown in the very primitive drawing below. Profibus dp communication tutorial.

Junction boxes for profibus pa are available. The shield must not be connected to the terminator and the impedance must be 100 ohms 20 from 7 8 to 39 khz. Acromag manufactures a line of i o modules that support profibus dp over rs485. This is not a problem since fms is totally compatible with the other versions of profibus.

Profibus was created in 1989 by the. The fieldconnex system offers several versions of standard junction boxes to connect the field devices to the trunk with connection points ranging from one through twelve field devices.

Fms is no longer supported by pi. The profibus dp must have bus terminators a 100 ohm resistor and a serial 1 uf one at the beginning and other at the end. As an already registered user simply enter your userame and password in the login page in the appropriate fields.
