Page Comparison

When using many tags with a data bridge function, data processing can take a few seconds. In comparison, within a single PLC, or for general device communication, data is processed in milliseconds. Avoid using the data bridge feature for values which that need to be consistently updated more than once per second.

Description

Model Type

(Block Base)

Select ‘Block base’ as the model type. Source and destination data will be exchanged based on contiguous blocks of memory. 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 once each time the trigger tag takes on 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 take into consideration 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 DWORDs in the block.

Source Block Start Addr / Tag

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

Source Handshake Start Addr / Tag

This is used internally when Xpanel reads data from the source device. You must enter a digital address from the source device. Do not use an address which that is already targeted by another program.

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 reads data from the destination device. You must enter a digital address from the destination device. Do not use an address which that is already targeted by another program.

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 device to Xpanel’s system memory and synchronizes it.

Sync. Properties

Select the frequency for synchronizing the data.

Trigger

Source and destination data are synchronized once each time the trigger tag takes on 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 take into consideration 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 DWORDs in the block.

Source Block Start Addr / Tag

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

Source Handshake Start Addr / Tag

This is used internally when Xpanel reads data from the source device. You must enter a digital address from the source device. Do not use an address which that is already targeted by another program.

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.

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 once each time the trigger tag takes on 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.

Enter the number of consecutive addresses (block size) for the block. This will take into consideration 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 DWORDs 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 reads data from the destination device. You must enter a digital address from the destination device. Do not use an address which that is already targeted by another program.

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.
