2.2 Confirming the Version LevelClicking Help on the menu bar causes the version of the CircLinkTM EVB Software to be displayed asshown in the window below.

2.3 Configuring the CircLinkTM EVB Software to Match the Evaluation Environment

When the CircLinkTM EVB Software is started, it assumes it has one host node and two IO nodes,configured as shown in Table 2.2. If the nodes are configured differently, follow the configuration stepsoutlined in Section 2.10 and Section 2.11 to ensure that the configuration assumed by the softwarematches that actually used by the nodes.

Note: The CircLinkTM EVB Software is designed to operate with only one PCM-2074 node; more thanone PCM-2074 node may not be added to the network.

If there is a mis-match between the configuration assumed by the CircLinkTM EVB Software and theconfiguration actually used by the nodes, the error message shown in Figure 2.3 will be displayed.Respond by clicking “No” twice, then follow the configuration steps explained in Section 2.10 andSection 2.11.

2.4 Running the CircLinkTM EVB SoftwareClicking the I/O Start button causes the CircLinkTM EVB Software to begin running with the OutputData Type that has been chosen in the Output Data Selection. In the example in Figure 2.1 above,“Demo1” has been chosen as the Output Data Type. The Demo1 Output Data Type causes the displayto show the status of the inputs and outputs of the host node and all of the IO nodes as shown inFigure 2.4.

When the CircLinkTM EVB Software starts running, you will notice that the IO Start button changes toan IO Stop button, and certain configuration windows are grayed out. In general, these parameters canonly be changed when the CircLinkTM EVB Software is in the idle/configuration state.

Data from the host node (in the case above, Node 1) is displayed in white. Data from the IO nodes isdisplayed in green, yellow or red depending on its type, as shown in the table below:

In Figure 2.4 above, Ports A and B are outputs on all IO nodes, with a value of 0x7FFE. The lowerbits of Port D are also used as outputs on all IO nodes, with a value of 0x00. The upper bits of PortD are used as Flag Outputs on all nodes, with all flags set. Port C is an input on all IO nodes, but its

value varies from node to node. On Node 2, Port C has a value of 0x00. On Node 3 it has a value of0x03, on Node 4, or 0xB4, and so on.

2.5 Stopping the CircLinkTM EVB Software from RunningWhen the CircLinkTM EVB Software is running, it can be stopped by pressing the IO Stop button; thisreturns it to the idle/configuration state.

2.6 Exiting the CircLinkTM EVB SoftwareClicking Exit on the Menu bar causes the message below to be displayed. Clicking OK causes theprogram to quit; clicking Cancel allows the program to resume.

2.7 Setting the Data Transmission IntervalWhen the CircLinkTM EVB Software is in the idle/configuration state, the data transition interval can beset, using the pull-down menu just above the IO Start button. The data transition interval can be set tispecified values between 50ms and 1 sec. When the CircLinkTM EVB Software is in the Run stat, thedata transition pull-down menu is grayed out, and cannot be changed. Figure 2.6 below shows thewindows involved with changing the Data Transmission Interval.

Notes:

Selecting either “Host Settings” or “I/O Node Settings” from “Settings” on the menu bar while the software is running causes it to enter the idle/configuration state immediately.

Selecting a data transmission interval of 5, 10 or 20ms may disable communication depending on PC performance. For slow PCs, settings below 30ms may cause CPU utilization to go above 100%, which can be determined from the Windows task manager by using Ctrl + Shift + Esc.

2.8 Selecting the Output Data TypeThe CircLinkTM EVB Software allows the user to select one of six programs, using the radio buttonsunder the box labelled “Output Data Selection”. Once the selection is made, it has to be confirmedusing the Select button. The window for configuring the “DEMO 1” Output Data Type is shown belowin Figure 2.7.

Table 2.4 below summarizes the six Output Data Types.

2.8.1 Using the Bit Assign Output Data Type

Figure 2.8 shows how to assign bits in the Bit Assign Output Data Type. A blue box indicates that thecorresponding bit is set to 1; a dark gray box means the corresponding bit is set to 0. In the examplebelow, Ports A and B are both set to “0x55h” respectively. Note that the ON/OFF state is changed bya single click of the left mouse button; double clicking a particular box results in no change of theON/OFF state.

2.8.2 Selecting the Output Data Type for a particular target node

The examples so far have shown how to set the Output Data Type for all nodes simultaneously,because the Node ID window is set to All. The Output Data Type can also be set for one node at atime by specifying a particular node in this window, as shown in Figure 2.9 below.

In order for the output data type to be changed, the Select button must also be clicked. If the Selectbutton is not clicked after a change is made, the change does not take effect. Also if the Node ID ofthe Host Node is specified in the Node Selection window, data transmission will not take place to theIO nodes.

2.9 Displaying Status InformationThe IO Node Status Box, located in the lower left-hand corner of the main display window, showsstatus information pertaining to a particular node that is selected using a pull-down menu. The IO NodeStatus Box shows the current status for a variety of node parameters; each parameter has its ownstatus button. Yellow indicates that a particular parameter is “1”; gray indicates “0”. Figure 2.10 belowshows the status window for the Host node at initialization and after reset. Note that two parameters- RCPUM and OPICDONE - are invalid, and can be ignored, in the case of the Host Node.

Figure 2.11 below shows the Status Windows for a EVB-2084 IO Node at initialization and after reset.

The meanings of the status window flags are given in Table 2.5 below:

The drop-down menu can be used to change the node for which the status is displayed. Note that thestatus information for an IO node is not updated until the host node actually communicates with thatnode. Selecting a non-participating IO node causes all status information to be displayed in yellow.

2.10 Configuring the PCM-2074 Host NodeTo configure the Host node, click “Settings” on the menu bar, then select “Host Settings” using the dropdown menu. This is shown below in Figure 2.12. The dialog box for the Host Node Settings is thendisplayed as shown in and Figure 2.13. This dialog box allows the user to change the configuration ofthe Host Node. Note that if the Host Settings Dialog box is activated while the CircLinkTM EVB Softwareis running, the software will immediately enter the idle state; the START button has to be clicked inorder for execution to resume.

Figure 2.13 below shows the status of the Host Node at the moment the window is created. Thewindow is not updated by the system and does not reflect changes in status that occur after it iscreated. The status of individual bits/pins is shown through check boxes.

Referring to the figures above, you will notice in the Initialize Node box that you have a choice betweenExt Pin Assign and Register Assign. For a PCM-2074 Host Node, Register Assign is the best choiceas shown above, because it allows you to update the Node ID, Max ID and CKP parameters. Onceyou have made all your configuration changes, click Set Node to have them take effect. To put theCircLinkTM EVB Software back in run mode, click the Start Button.

Side effects - note that the Page Size affects the pull-down menu choices for Node ID and Max ID.When the Page Size is set to 64 Bytes/Page, the Node ID and Max ID pull-down windows allowchoices of 1 to 15. When the Page Size is set to 128 Bytes/Page, these windows allow choices of 1to 7. Also the choice of Page Size for the Host Node must match the Page Size set by JP4 on all ofthe EVB-2084 IO Nodes. Any mismatches will cause communication errors.

Figure 2.14 below shows the configuration window when the Initialize Node box is set to Ext PinAssign. Note that the Node ID, Max ID and CKP parameters are grayed out and cannot be changed.

These parameters cannot be changed.



2.11 Configuring EVB-2084 IO NodesTo configure IO nodes, click “Settings” on the menu bar, then select “IO Node Settings” using the dropdown menu. This is shown below in Figure 2.15. The dialog box for the Host Node Settings is thendisplayed as shown in Figure 2.16. This dialog box allows the configuration of the IO Nodes to bechanged. Note that if the IO Node Settings Dialog box is activated while the CircLinkTM EVB Softwareis running, the software will immediately enter the idle state; the START button has to be clicked inorder for execution to resume.

The configuration window (below) shows the status of a particular IO Node that is chosen by the IONode Select pull-down menu. Whenever this pull-down menu is changed, the configuration window isupdated with the current configuration of the IO node. The window is not updated after that by thesystem.

Note that for IO Node, certain parameters such as Node ID and MAX ID are determined by externalconfiguration pins only and cannot be changed via configuration registers. Therefore these parameterscannot be updated using the IO Node Configuration Window shown above. Once you have made allyour configuration changes, click Set Node to have them take effect on the node chosen. You can alsoapply a configuration to all nodes at once by clicking the Set All Node button. The Reset buttonrefreshes the window with the current configuration state of the chosen IO node. Clicking Reset beforeSet Node or Set All Node will cause any changes you have made to be lost. Clicking Reset after SetNode or Set All Node can be used to confirm that the IO Node reflects the changes you just made.The Cancel button exits the IO Node Configuration Window.

2.12 Dumping the Memory Contents of the PCM-2074Returning to the Main Window of the CircLinkTM EVB Software, in Figure 2.1, clicking “Memory” on themenu bar at the top of the window causes the PCM-2074 Host Node to dump its memory contents.The display format depends on the Page Size chosen (64 or 128 bytes). Both formats are illustratedbelow.

Each page in the memory dump shows the configuration information for the corresponding IO node.The information is a snapshot made when the memory dump window is opened; the information is notupdated. The vertical scroll bar can be used to scroll through all the pages.

3 Error MessagesIf errors are detected at start-up or during run-time, appropriate error messages will be displayed bythe software. There are three types of errors that can be displayed:

System Errors - show errors returned by the Windows O/S.

Communication Errors - Detected when packets are being transmitted or received

Operation Errors - Detected during operation of the CircLinkTM EVB Software.

3.1 System Error MessagesThese messages are displayed when a Windows system function that is called by the CircLinkTM EVBSoftware detects an error. System functions that are used include open/close functions and I/O requestcalls to the device drivers. The message indicates the type of error and asks whether the softwareshould quit or continue. The example show below occurs when there is an error opening the devicedriver. In this particular case, click “Yes” (close) and confirm that the device driver has been correctlyinstalled before re-invoking the CircLinkTM EVB Software.

3.2 Communication Error MessagesThese kinds of errors cause a message like the one below to be displayed. Common causes ofcommunication errors include:

Mismatch in settings between the Host Node and one or more IO Nodes

Attempting to communicate with a non-existent node.

3.3 Operation Error MessagesCommon causes of these kinds of errors are choosing invalid or incompatible configuration settings.the figure below shows two typical examples. In the first case, choose a different node ID. In thesecond case, change the Flag settings.
