Setting up communication between AB & Siemens (Part. 3)
Configuring the MVI56-PDPS Module
Set Up the Project
To begin, start ProSoft Configuration Builder. If you have used other Windows configuration tools before, you will find the screen layout familiar. ProSoft Configuration Builder's window consists of a tree view on the left, an information pane and a configuration pane on the right side of the window. When you first start ProSoft Configuration Builder, the tree view consists of folders for Default Project and Default Location, with a Default Module in the Default Location folder. The following illustration shows the ProSoft Configuration Builder window with a new project.
Your first task is to add the MVI56-PDPS module to the project.
1. Use the mouse to select "Default Module" in the tree view, and then click the right mouse button to open a shortcut menu.
2. On the shortcut menu, choose "Choose Module Type". This action opens the Choose Module Type dialog box.
3. In the Product Line Filter area of the dialog box, select MVI56. In the Select Module Type dropdown list, select MVI56-PDPS, and then click OK to save your settings and return to the ProSoft Configuration Builder window.
Adding a Project
To add a project to an existing project file:
1. Select the Default Project icon.
2. Choose Project from the Project menu, then choose Add Project. A new project folder appears.
Adding a Module
To add a module to your project:
1. Double-click the Default Module icon to open the Choose Module Type dialog box.
2. On the Choose Module Type dialog box, select the module type.
Or
1. Open the Project menu and choose Location.
2. On the Location menu, choose Add Module.
[MODULE]
The module section contains the data that applies to the whole module and includes the backplane data transfer parameters.
[Module]
Module Name : MVI69-PDPS Communication Module DEFAULT
[BACKPLANE]
The backplane section contains the data that applies to the backplane data transfer parameters.
[Backplane]
Read Register Count : 122
#Number of words to move from MVI to
#Processor (PROFIBUS Output)
Write Register Count : 122
#Number of words to move from Processor to
#MVI (PROFIBUS Input)
Block Transfer Size : 60
#Number of data words for I/O transfer
#(60, 120 or 240)
[PROFIBUS SLAVE]
The PROFIBUS Slave section contains the data that applies to the PROFIBUS Slave parameters.
Slave Address
0 to 125
The parameter specifies the node address on the PROFIBUS network for the slave emulated in the module. Each node on the network must have a unique address.
Swap Input Bytes
Yes or No
This parameter specifies if the data in the input data area of the module is to be byte swapped. If the order of the bytes in the words stored in the database is not correct, use this option. A value of Yes causes the module's program to swap the bytes in each word. A value of No indicates no byte swapping will occur.
Swap Output Bytes
Yes or No
This parameter specifies if the data in the output data area of the module is to be byte swapped. If the order of the bytes in the words stored in the database is not correct, use this option. A value of Yes causes the module's program to swap the bytes in each word. A value of No indicates no byte swapping will occur.
Comm Failure Mode
No xfer on fail
xfer on comm fail
This parameter sets the data transfer mode of the module's PROFIBUS output image to the internal database when a communication failure on the PROFIBUS interface is detected. If the parameter is set to "No xfer on fail", the output image will continue to be transferred. If the parameter is set to "xfer on comm fail", the output image will not be transferred and the last values will be retained.
Comm Timeout Multiplier
1 to 10
This parameter sets the communication timeout value for the module. The value entered is multiplied by 125 milliseconds to determine the actual timeout value. For example, a value of 1 specifies a communication timeout of 125 milliseconds.
Download the Project to the Module
In order for the module to use the settings you configured, you must download (copy) the updated Project file from your PC to the module.
To Download the Project File
1. In the tree view in ProSoft Configuration Builder, click once to select the MVI69-PDPS module.
2. Open the Project menu, and then choose Module / Download. The program will scan your PC for a valid com port (this may take a few seconds). When PCB has found a valid com port, the following dialog box will open.
3. Choose the com port to use from the dropdown list, and then click the Download button.
The module will perform a platform check to read and load its new settings. When the platform check is complete, the status bar in ProSoft Configuration Builder will be updated with the message "Module Running".
