Please find below a list of frequently asked questions (FAQs) with regards to Software. More extensive FAQs can be found at the Rockwell Automation Knowledgebase.

| A. 1. From the DDE/OPC Topic Configuration dialog box, click New, or right-click in the Topic List and select New. A default topic named "NEW_TOPIC" is created.
2. From the Data Source tab, browse to the target device for this topic.
3. Enter a name for the new topic in the Topic List (49-character limit). Enter any specific information for the new topic on the Data Collection or Advanced Communication tabs.
4. Click Apply to add the new topic.
If you enter any specific information for the new topic on the Data Collection or Advanced Communication tabs, click Yes when prompted with the message "Are you sure you want to update topic (topic_name)?"
5. When you are finished adding topics, click Done to close the DDE/OPC Topic Configuration dialog box. |

| A. RSLinx Classic now automatically starts as a service, not an application. Running as a service eliminates problems when OPC clients (particularly remote OPC clients) need to start/access RSLinx Classic data. RSLinx Classic can be forced to start as an application by selecting Start > Programs > Rockwell Software > RSLinx > RSLinx Classic Launch Control Panel.

|
| A. If RSLinx Classic is automatically started by COM (OPC clients) or by DTL32 (RSLogix products, custom C applications, etc.), no splash screen appears and the RSLinx Classic main window is not shown. In this case, the RSLinx Classic application is said to be running "headless." RSLinx Classic does however appear as a system tray icon, just as if it were running as a service. To view the existing RSLinx Classic, click the icon, right-click the icon and select Restore, or from the Start menu select Programs > Rockwell Software > RSLinx > RSLinx Classic. Any of these actions will bring the running RSLinx Classic to the foreground. To shut down RSLinx Classic, right-click the icon and select Shutdown, or right-click the icon, select Restore, and choose File > Exit and Shutdown. |

| A. A red X in RSWho indicates that an error currently exists with a previously recognised node. The red X indicates a communication status error, such as unplugging a recognized device. For example, if Autobrowse is enabled, RSWho recognizes nodes during the browse cycle and stores the node information. During subsequent browse cycles, if an error occurs, such as a communication cable being pulled from a device, RSWho places a red X over the device to indicate that it cannot be recognized. Red X's will not appear if you are working in offline mode (Autobrowse is disabled or cleared). |
|
| A. If a module displays as a yellow question mark in RSWho, the module does not have an associated Electronic Data Sheet (EDS) file installed, and therefore can not be recognised by RSLinx Classic. The software considers this to be an unknown device because it has not been registered. In this case, the correct online name displays but the icon does not appear. To resolve this condition, use the EDS Hardware Installation tool to register the proper EDS file. |
|
| A. A BOOTP server or BOOTPS is software that detects BOOTP requests and transfers the needed configuration information for a device. Its configuration file contains a list of hardware addresses and their associated needs. Often this is just an IP address, but it can also have a file and directory associated with it. The PLC-5/E processors require only an IP address. The 5820-EI module requires an IP address and a binary file, SGMPCCC.BIN. In the case of the 5820-EI module, the BOOTP server must also have TFTP capability, to be able to transfer the file. Under UNIX, you would run a BOOTP daemon, which would always be running. Under DOS, you would probably run BOOTP server software when needed. |
