Modbus Cache Table - Delta DVW-W02W2-E2 User Manual

3.3.3 MODBUS Cache Table

The transmit speed of Ethernet interface is faster than serial interface, so the device on Ethernet side usually
need to spend much time to wait the data from serial side after they send the request message to the device on
serial side. MODBUS Cache Table provide user for configure the device information (ex. Station ID, MODBUS
address...etc.), and DVW can send request message for get the data from the device on serial side according
to the MODBUS Cache table in advance. When the device on Ethernet side sends the request to DVW series,
then DVW can response the data immediately. Because DVW series don't need to forward the request
message to the device on serial side again, it already get the data in advance. So this only can be enabled
when the operation mode in MODBUS Slave mode.
