Description

Model Name

Enter the model name in the text field. Duplicate names are not allowed.

Model Type

Select the method for synchronizing device data. You can exchange data based on individual tags, contiguous memory blocks, or system memory.

Item

Description

Model Type

(Tag Base)

Select ‘Tag base’ as the model type. Source and destination data will be exchanged based on Xpanel tags. This method is used when the number of data points is small, or when values are stored in different values on different devices. You must add source and destination tags (addresses) after configuring the model settings.

Sync. Properties

Select the frequency for synchronizing the data.

Always

Source and destination data are synchronized immediately when source data is changed.

Trigger

Source and destination data are synchronized when the selected tag has a non-zero value. You can choose an analog or digital tag/device address.

Periodically

Source and destination data are synchronized at a specified interval. You can assign an interval from 1 to 10,000,000 seconds.

Using the data bridge function, data is processed on a time scale of seconds. Within a single PLC, or for general device communication, data is processed in milliseconds. Avoid using the data bridge feature for values which need to be updated more than once per second.

Item

Description

Model Type

(Block Base)

Select ‘Block base’ as the model type. Source and destination data will be exchanged by memory block units. This method is used for transferring consecutive data addresses between destinations.

Sync. Properties

Select the frequency for synchronizing the data.

Trigger

Source and destination data are synchronized when the trigger tag has a non-zero value. You can choose an analog or digital tag/device address.

Periodically

Source and destination data are synchronized at a specified interval. You can assign an interval from 1 to 10,000,000 seconds.

Block Size

Enter the number of consecutive addresses (block size) for the block. This will be based on the data type of the starting block. For example, if the block starts with a DWORD (INT32, UINT32, Float, etc.), then the block size represents the number of DWORD's in the block.

Source Block Start Addr / Tag

Enter the starting tag or address (on the source device) of the continuous addresses to send to the destination.

Source Handshake Start Addr / Tag

This is used internally when Xpanel reads the data. You must enter a digital tag including the same I/O device assignment as the source block.

Destination Block Start Addr / Tag

Enter the starting tag or address (on the destination device) for receiving block data from the source.

Destination Handshake Start Addr / Tag

This is used internally when Xpanel sends the data. You must enter a digital tag including the same I/O device assignment with destination block.

Item

Description

Model Type (Upload Data to Sys-mem)

Select ‘Upload data to sys-mem’ as the model type. This model reads data from the source to Xpanel’s system memory and synchronizes it.

Sync. Properties

Select the frequency for synchronizing the data.

Trigger

Source and destination data are synchronized when the trigger tag has a non-zero value. You can choose an analog or digital tag/device address.

Periodically

Source and destination data are synchronized at a specified interval. You can assign an interval from 1 to 10,000,000 seconds.

Block Size

Enter the number of consecutive addresses (block size) for the block. This will be based on the data type of the starting block. For example, if the block starts with a DWORD (INT32, UINT32, Float, etc.), then the block size represents the number of DWORD's in the block.

Source Block Start Addr / Tag

Enter the starting tag or address (on the source device) of the continuous addresses to send to the destination.

Source Handshake Start Addr / Tag

This is used internally when Xpanel reads the data. You must enter a digital tag including the same I/O device assignment as the source block.

Start Address of System Memory

Assign the starting address in system memory for receiving data. Source data is transferred to system memory beginning at the start address and ending at an offset location determined by the block size.

Item

Description

Model Type (Download Data from Sys-mem)

Select ‘Download data from sys-mem’ as the model type. This model writes system memory data to the destination device.

Sync. Properties

Select the frequency for synchronizing the data.

Trigger

Source and destination data are synchronized when the trigger tag has a non-zero value. You can choose an analog or digital tag/device address.

Periodically

Source and destination data are synchronized at a specified interval. You can assign an interval from 1 to 10,000,000 seconds.

Block Size

Enter the number of consecutive addresses (block size) for the block. This will be based on the data type of the starting block. For example, if the block starts with a DWORD (INT32, UINT32, Float, etc.), then the block size represents the number of DWORD's in the block.

Destination Block Start Addr / Tag

Enter the starting tag or address (on the destination device) for receiving block data from system memory.

Destination Handshake Start Addr / Tag

This is used internally when Xpanel sends the data. You must enter a digital tag including the same I/O device assignment with destination block.

Start Address of System Memory

Assign the starting address of system memory for transferring data. System memory data is transferred to the destination and ends at an offset location determined by the block size.

Item

Description

Original Addr / Tag

Enter the tag name or address on the source device to send data from.

Target Addr / Tag

Enter the tag name or address on destination device to transfer data to.
