ICP DAS WISE User Manual
Please Note: After the "Baudrate" is selected, the system will
automatically generate a proper value in the "Silent Interval" field.
For each Modbus RTU Slave module has different Modbus
command process capability, the response time for sending result
from Modbus RTU Slave module to WISE might be different. The
user can adjust this value to most appropriate time interval, such as:
extend this value to make sure every Modbus RTU Slave module
connected to the WISE has enough time to process the Modbus
command, or shorten this value to improve the efficiency of the
polling mechanism between Modbus RTU Slave module and WISE.
