21.5.2 Structure of Extended Scripts

Extended Scripts are scripts used for communicating between the display unit's internal serial port and connected input/output devices.

For Extended Script data management, as shown in the following picture, data is stored in databuf0 to databuf3 via the Send/Receive Buffer. Databuf is not divided by address, so store the data in internal memory before editing the data on the device/PLC.

Receive Buffer/Send Buffer

For communication with the device/PLC, this acts as a bit memory space which distinguish sent and received data in real time.

databuf0 - databuf3

These are byte (8-bit) memory spaces used for data storage. The buffer size is 1 KB.
