Note
• Depending on the Data Output Number setting for the line, you can set from 4 to 64 data items for output with one data
output processing item.
Examples:
DINT16: You can register up to 16 data items.
LREAL 24: You can register up to 24 data items.
Refer to Communications Specifications Settings (p.63) for the number of data items that you can output for each Data
Output Number setting.
If you need to output more data items than given above, use more than one Output Unit.
However, the data is output to the same destination, so if you do not control the output, the output data that was output
first will be overwritten by the output data that is output after it.
Use the following method to read each set of output data.
• Controlling Data Output with Handshaking
If handshaking is used to control data output, the timing of outputting the data is controlled by I/O signals.
Each time that data is output, read the output data and move it to a different part of I/O memory in the PLC.
Refer to Data Output Control with Handshaking (p.32) for more information on handshaking.
• Data is output in the order of registration in the measurement flow, with each data output processing item executed at a
different timing. (Data output is executed in the order that it is registered in the measurement flow.) Reference:
