4 Product function introduction
4.1DI input
4.1.1Switch input DI acquisition
Switch input DI measurement level signal or edge pulse signal (rising edge, falling edge). Support dry node
collection, support DI counting function, the maximum count is 65535 (the count is automatically cleared if it
exceeds 65535).
The switch input DI branch has three trigger modes: rising edge, falling edge and level (default rising edge
trigger).
The clearing method supports automatic clearing and manual clearing (default automatic clearing).
4.1.2 Input filtering
When the switch input DI collects the signal, it needs to keep several sampling cycles before confirming. Filter
parameters can be set in the range of 1 to 16 (default 6 sampling periods, 6*1kHz).
It can be configured with the host computer through instructions.
4.2 Modbus gateway
The device can transmit non local Modbus instructions from the network/serial port to the serial port/network,
and the local Modbus instructions can be executed directly.
4.2.1 Modbus TCP/RTU Protocol Conversion
After being turned on, the Modbus TCP data on the network side will be converted into Modbus RTU data.
4.2.2 Modbus address filtering
This function can be used in certain host software or configuration screens as the host to access the device
serial port, and the gateway function of the device is used. When the slave is on the network side and the Modbus
TCP to RTU function is enabled, the presence of multiple slaves on the bus may cause data confusion. At this time,
enabling address filtering can ensure that only the specified address can pass through the device; When the
parameter is 0, data is transmitted through, and when the parameter is 1-255, data is only transmitted through the
set slave address.
