Hello,

I need info on the application usage. On p. 50 of 00-02-0875 PV Config Studio Core, it says the following:

NOTE: The applications are defined in a separate document. Please see: 00-02-0800 PowerVision Studio 2.6 Application Reference Manual.

I searched the Murphy website for this document. No results.

I am trying to bring DTCs in from Modbus serial port, but do not have the information to know how to do it, as the document that might help is not available.

Also asked a question on Monday and still waiting for some help. ANY HELP!!

My customer is starting up the equipment today PLEASE HELP!

Phil

Dear Dr. Phil,
Attached is the 00-02-0873 PowerVision Configuration Studio Application Reference Manual. There is also a Programming and Page Designer manuals attached which may be of value. I think you already have the 00-02-0875 Core Manual.

On a Display, one can setup Modbus Gauge variables which can be read over the Modbus as holding registers. There is no defined Modbus, but you can typically provide Gauge variables. If you set up the Display as a Modbus Master, it will periodically broadcast Engine RPM, Oil Temperature, Oil Pressure, etc. as Gauge variables. If the display is a slave, you would have to poll for these gauge variables.

Most of the time DTC messages (such as DM1 messages) come in from an ECU, a transmission controller, or other devices. These messages are captured in the DM1 message queue. You can tell the DM1 to go to the first record with "DM1GoToFirst" action which copies the first diagnostic message into the DM1 variable. Check the Dm1.VariablesWriteOk to see if the data is transferred successfully. All of these DM1 variable fields are strings. You can get the Dm1.SPN and Dm1.FMI but you should convert to integers if your are considering updates to the Modbus. Use the "DM1GoToNext" action to go to the next DM1 message and repeat the process. You may need some handshaking to tell the Modbus when you have received a message.

I hope I'm on target with what you are trying to do, but without more specific information I do not have a good example to provide.
Thanks,
Phil Cebuhar

Thank you.
