9.9 Active I/O Sending Setting
WISE equips the "Active I/O sending" function. There are two parts in this
function: "I/O Data Table Setting" and "Active Sending of I/O Data Table".
Even though WISE allows to connect with multiple I/O modules at the
same time, however, the channel data of each I/O module that WISE
received is located in the different Modbus Address memory block of WISE.
Therefore, when using SCADA software to retrieve the data, the SCADA
software must poll each I/O module‟s channel data separately. It is
impossible to poll all WISE I/O modules‟ channels data at one time. In
order to improve the efficient of the data communication between WISE
and SCADA software, WISE provides "Active I/O Sending" function. It
allows to copy the I/O channels data from different I/O modules and puts
them into a continuous Modbus address memory block, and then SCADA
software can retrieve all I/O channel data from different modules by using
one single Modbus command. Comparing to traditional polling mechanism,
it will greatly save time and polling attempts.
Please note: The SCADA software must equip the Modbus TCP Slave
function to receive the content of I/O Data Table that sent by WISE.
