Introduction
The MDCL-705i collects data using the Modbus RTU protocol to poll the data out of the device. For each data you want to retrieve, just define the Modbus RTU commands in a CSV file and import it via the web interface. The MDCL-705i can perform up to 250 polling definitions. Its internal shared memory has four tables (Coils, Discrete Input, Input Registers and Holding Registers) to store the polled data. Each table can store up to 9600 registers. It allows up to 8 simultaneous Modbus TCP connections to get the polled data at one time.
