How do I configure PROFIBUS devices?
How do I configure PROFIBUS devices?
PROFIBUS Configuration
- In RMCTools, go online with the RMC.
- In the Project Pane, expand the Modules folder and double-click the PROFIBUS module.
- On the PROFIBUS page, enter the desired station address. Use any station address between 1 and 125.
- Click OK. The change will automatically be downloaded to the RMC.
How do you use PROFIBUS communication?
The communication basis for PROFIBUS lies in the cyclic data exchange between PLCs (masters) and devices (slaves). PROFIBUS components communicate using the PROFIBUS DP (Decentralized Periphery) communication protocol, which is the same for all applications and which allows cyclical and acyclical communication.
How do I test a PROFIBUS connector?
Probably the best way to physically check a Profibus cable is to use the Siemens BT200 tester , which will test for Cable A/B breaks , cable A/B being swopped , cable shield breaks and incorrect terminations etc.
What is DP in PROFIBUS?
PROFIBUS DP stands for Decentralized Periphery. The name refers to the I/O connections, which use completely decentralized high-speed serial communication to connect to a central controller.
How is PROFIBUS wired?
The Cable. For Profibus networks a shielded AWG 22 or 0.34 mm² twisted pair cable is used. The standard isolation color of a Profibus DP cable is purple, and the two wires in the twisted pair are usually green and red. But the colors of the cable are not important.
How is PROFIBUS connected?
PROFIBUS PA devices are not connected directly to the controller. This sits on the faster PROFIBUS DP network and is reached through a coupler or link. The coupler/link acts as a network interface and supplies the power to the bus.
What is PROFIBUS communication basics?
Profibus (from process field bus) is a protocol for field bus communication in automation technology. Profibus links automation systems and controllers with decentralized field devices such as sensors, actuators, and encoders. Profibus networks exchange data using a single bus cable.
How many nodes can be connected to PROFIBUS?
In PROFIBUS networks, each segment can have a maximum of 32 nodes, counting master and devices. The maximum number of nodes with addresses in the overall network is 126.
