This string can contain a max of 8 characters. c. Enter a Starting Address (1-based). d. Enter the # of Points to write. This will allocate the number of the data type selected. Real Time Automation, Inc.
Mapping - Transferring Data between Devices There are 5 ways to move data from one protocol to the other. You can combine any of the following options to customize your gateway as needed. Option 1 – Data Auto-Map: The gateway will automatically take the data type (excluding strings) from one protocol and look for the same data type defined in the other protocol. If there isn’t a matching data type, the gateway will map the data to the largest available data type. See Data Auto-Map section for more details.
Display Mapping and Values The Display Data and Display String pages are where you can view the actual data for each mapping that is set up. Display Data Click the Display Data button to view how the data is mapped and what the values of each mapping are. Here you will see how each data point (excluding strings) is mapped. To view, select the device from the dropdown menu and click View to generate the information regarding that device.
If there are values of “- -“ on this page, it indicates that the source has not yet been validated and no data is being sent to the destination. The example below reflects the Modbus to PLC flow of data. The Modbus (right side) is the source and the PLC (left side) is the destination. • The 460 gateway has received valid responses from Modbus registers 400001-400005 and therefore can pass the data on to the PLC tag called MC2PLC_INT.
Display String Click the Display String button to view how the string data types are mapped and what the values of each string are. Here you will see how each string from each protocol is mapped to the other. To view, select the source or destination group and the String from the dropdown menu to generate the information regarding that device. The string data will be displayed in both hex and ASCII.
Data and String Mapping – Auto-Map The Auto-Map function looks at both of the protocols and will map the data between the two protocols as best as it can so that all data is mapped. Inputs of like data types will map to outputs of the other protocols like data types first. If a matching data type cannot be found, then the largest available data type will be used. Only when there is no other option is data truncated and mapped into a smaller data type.
Data Mapping – Explanation Below are the different parts that can be modified to make up a data mapping. 1. Enable (red box above): Check to enable mapping. If not checked, this mapping is skipped. 2. Source Field (yellow box above) : a. Group - Select the data group you set up in the protocol config to use for this mapping. b. Start - This is the starting point for this mapping. c. End - This is the final point to be included for this mapping. 3. Manipulation Area (green box above) : a.
Data Mapping – Adding Diagnostic Information Data Mapping offers 5 different types of information in addition to any scan lines specified for each protocol. IMPORTANT NOTE: Only add Diagnostic Information AFTER both sides of the gateway have been configured. If changes to either protocol are made after diagnostic information has been added to the mapping table, it is necessary to verify all mappings. Remapping may be necessary. 1. Temporary Ram (Int 64) a.
may be beneficial to know if a Server/Slave device is down. By using this Network Bitmap Status you can expose the connection statuses of individual devices. b. 0x00000002 shows that only device 2 is connected c. 0x00000003 shows that only devices 1 and 2 are connected d. 0x00000004 shows that only device 3 is connected 5. Status_XY a. There are two Statuses provided, one for each protocol. This gives access to the overall status of that Protocol.

After you click this button, you will be prompted to confirm if this is really what you want to do. Click OK to proceed to Manual Map mode or click Cancel to remain in Auto-Map mode. There are 2 options on how to proceed from here. 1) To keep the mappings that are already configured press OK. a.
Mapping – Manual-Map Mode to Auto-Map Mode To transition from Manual-Map mode to Auto-Map mode, click the Auto Map Mode button. After you click this button, you will be prompted to confirm if this is really what you want to do. Click OK to proceed to delete all current mappings and go to Auto-Map mode. Click Cancel to keep all mappings and remain in Manual-Map mode. NOTE: Once you revert back to Auto-Map mode there is no way to recover the mappings you lost. Any mappings you added will be deleted as well.
View Data Mapping as Text The View as Text page displays the point to point mapping(s) you set up in the Data Mapping section. This will also display any manipulation(s) that are configured. Each line on this page will read as follows: Mapping number: source point Len: Number of points mapped -> manipulation (if blank then no manipulation) -> destination point If you are looking for a specific point to see if it is mapped, you can do a find in this text box for your point in question.
View String Mapping as Text The View as Text page displays the string mapping(s) you set up in the String Mapping section. Each line on this page will read as follows: Mapping number: source point -> Copy -> destination point If you are looking for a specific point to see if it is mapped, you can do a find in this text box for your point in question. Example: you defined 20 String Tags in the PLC and want to see if “Test_String” in the Logix PLC is mapped.
Security Configuration You can configure Security for 3 administrators, 5 users, and 1 guest. THIS IS NOT A TOTAL SECURITY FEATURE The security feature offers a way to password protect access to diagnostics and configuration on the network. The security feature does not protect against “Air Gap” threats. If the gateway can be physically accessed, security can be reset. All security can be disabled if physical contact can be made.

Alarm #: The reference number to the given alarm on the alarm setup page. 6. Name: The name of the alarm. 7.
Alarms – Clear When an alarm is cleared, the following will occur: 1. A one-time notification will be sent to the email associated with the alarm. a. For duplicate emails to occur, the alarm must become active and then be cleared again. 2. Total # Alarms Active will decrement. Last Active Alarm will not be changed. 3. Status of the Individual Alarm will be reset to OK. Real Time Automation, Inc.
Change of State (COS) Configuration The gateway, by default only writes when data has changed. The gateway also waits to write any data to the destination until the source protocol is successfully connected. Default values should fit most applications. Change these values with caution as they affect performance. 1. Stale Data Timer: If the data has not changed within the time allocated in this Stale Data Timer, the data will be marked as stale within the gateway and will force a write request to occur.
Diagnostics Info The Diagnostic page is where you will be able view the gateway’s translations and protocol specific status information. For protocol specific diagnostic information, refer to the next three pages. Diagnostics – Data and String Mapping The Diagnostics->Diagnostic Info->System section displays the number of translations that are enabled, for both Data and String data types, the number of mappings that have an error, and the first mapping that has an error.
