Common questions



DPV1: Acyclic Data Exchange, Process Alarm Handling (process automation) DPV2: Clock Synchronization & Time Stamp (drives) It’s important to note that the versions build one on the other and are interoperable and backward compatible.

What voltage does PROFIBUS use?

Both the slave and master PROFIBUS DP test specifications state that the differential voltage between A- and B-lines shall be a minimum of 4 V and a maximum of 7 V. The signals of the A- and B-line are measured against DGND. The difference of the amplitudes shall be less than 0.5 V.

What is Profibus connector?

The PROFIBUS DB9 connector is used in most IP 20 environments and is the best solution for high transmission speeds. The connector is perfect for establishing a connection between cables and to create the ideal branch. The majority of connectors have coils to suppress noise and reflections.

How does Profibus PA work?

PROFIBUS PA is linked via coupler to PROFIBUS DP. The coupler translates the DP telegrams that come from the master to PA telegrams (data and power supply) on the same two wires. The answers of the PA instruments are translated back to PROFIBUS DP. The translations are electrical, because the protocol remains intact.

How many wires are in Profibus cable?

The Profibus Cable: How To Make Your Own The connections are fairly simple since the cable only has two wires and a shield. But you should be careful.

How many wires are in PROFIBUS cable?

How does PROFIBUS cable work?

The PROFIBUS DP network is a multi-master token network – that means when there are two or more masters in the system, a token giving the right to talk to the field devices is passed from master to master, and each gets a share of the communication time.

Which is DPV1 module does PROFIBUS support?

The PS69 PROFIBUS DP Master module expands the functionality of ’s CompactLogix / MicroLogix family of processors to include PROFIBUS. This module supports both I/O control and messaging, thus integrating DPV0 and DPV1 functionality into CompactLogix / MicroLogix.

How to use PROFIBUS FDT comdtm on PC?

The FDT PROFIBUS comDTM and a compatible FDT 1.2.1 frame application connect multiple device DTMs to their respective PROFIBUS connected field instruments using the Ethernet port on the PC and PROFIBUS DPV1 master module. The software is available as a free download.

Which is Prosoft software does PROFIBUS use?

PROSOFT.fdt is FDT style configuration software and a communication DTM is included with the module allowing easy configuration of the PROFIBUS Master and network slave devices. The master and network configuration are stored in the FLASH memory of the module.

How does the Profibus ps69-dpm module work?

The PS69-DPM is a CompactLogix / MicroLogix compatible, PROFIBUS certified module, which enables controllers to communicate with a PROFIBUS network. The configuration and diagnostic of the PROFIBUS system is done via the serial diagnostic interface of the module using the System Configuration tool .
