How can I monitor module and slave status with the MVI56-PDPV1 and other PDPMV1 PROFIBUS master modules?

The PDPMV1 operating state is stored in the MVIxxPDPMV1.Status.Fieldbus.FB_op_state tag: 00 = Offline 40 = Stop 80 = Clear C0 = OperateTo determine slave status, the MVIxxPDPMV1.Status.Fieldbus.FB_Slave_Data_xfer array contains a bitmap of all the PROFIBUS ...

I need to set up a ProSoft PROFIBUS Master to talk to a Siemens S7-300 series CPU that is set up as a PROFIBUS Slave. How do I do that?

The attached file shows how to set up a S7-315 CPU to be a PROFIBUS DP Slave to a ProSoft MVI56-PDPMV1 PROFIBUS Master and was written for that specific application. However, many of the setup steps apply to other S7 configurations and other ProSoft PROFIBUS Masters.Please see th...

What direction does the data flow in my PROFIBUS Slave module's Input / Output registers?

The data movement in the PROFIBUS Slave module (PDPS) is as follows: Input registers (0 - 99) move from the PROFIBUS Slave module to the PROFIBUS Master. Output registers (100 - 199) move from the PROFIBUS Master to the PROFIBUS Slave module. With the PROFIBUS protocol, input and...

Does ProSoft or ProLinx support Profibus PA?

By itself the module does not support PROFIBUS PA. However, when used with a PROFIBUS DP/PA coupler, it is possible to communicate with the ProLinx module via PROFIBUS PA.Related Keywords:PROFIBUS PA DP PDPS PDPM...

How do I setup my 3170-PDP in Step 7 software?

Make sure to drop the "3170-PDP 1.2 status" information into the first slot, then each of your I/O modules after that. Any unused slots must have a "flex I/O empty slot" defined in the configuration for that slot setup....

Can a ProSoft PROFIBUS DP v1 Master solution communicate directly with other PROFIBUS DP v1 Masters?

Not all PROFIBUS DP v1 Master devices support Master to Master or "peer-to peer" messaging, as some do. ProSoft PROFIBUS DP v1 Master solutions (those with -PDPMV1 in their part numbers) do not have peer-to-peer support built-in. However, a PDPMV1 ...

Can a ProSoft PROFIBUS DP v1 Master solution also be configured as a Slave to another Master?

Sorry; but this is not possible. However, a ProSoft PROFIBUS DP v1 Master can be configured to pass data to and from another PROFIBUS DP Master by using a third-party DP-to-DP coupler....

I am trying to download my PROFIBUS PDPMV1 Master/Slave configuration from the ProSoft Configuration Builder (PCB) "PROFIBUS - PDPMV1" Online-Download Configuration menu option; and it is lo

Please do not use the "Online - Download Configuration" menu option from inside the PCB "PROFIBUS - PDPMV1" configuration window. If you do this, it will lock up PCB, requiring you to shut it down and restart it to clear the error.Instead, exit the "...

I have a PROFIBUS DP network with ProSoft PROFIBUS DP Master solution that appears to be operating normally (no bus faults, slaves report "OK"), but I am unable to control my devices. What

Many things can result in these symptoms. One of the most common causes is that not all slave manufacturers use a standard byte order. It is very possible that when you think you're sending a value of "1" to a slave's bit address 0, you may be...

How to resolve an issue where Siemens Step 7 software displays a message indicating that the ProSoft GSD file cannot be interpreted.

PROFIBUS DP GSD file names should be limited to eight characters. File names longer than eight characters will cause this error.Delete the excess characters in the file name so that the file name contains no more than eight characters before the .gsd extension.Related Keywords:P...

I can't get my ProSoft PROFIBUS DP V1 Master to talk to all of the Slave Nodes on my PROFIBUS network. What might the problem be?

The question has several possible answers. Most of them are obvious to anyone familiar with PROFIBUS networks, so we won't mention them all here.However, there is one remote possibility that has been known to cause problems in the past that might bear checking. The pa...

My Profibus Master (PDPMV1) card is not communicating and will not go into RUN mode but does not show an error in the ProSoft Configuration Builder software, why?

Due to GSD file errors or device configuration errrors the module may not be able to go into RUN mode. However depending on the type of error (invalid GSD file or exceeding parameter data configuration) the ProSoft Configuration Builder software&nbs...

Will the PS69-DPM work with a Siemens 157-xxxxx-0XA0 DP/PA coupler at the baud rate 45.45 Kbit/s?

The PS69-DPM does not communicate natively at 45.45 baud.To communicate through this DP/PA coupler you will need theSiemens Simatic DP Link....
