Feature:
Function Description:
NO : Relay normally open contact
COM : relay common contact
NC : Relay normally closed contact
''Open'' :The NO connects to the COM, and the NC disconnects the COM
''Close'' :The NO disconnects the COM, and the NC connects to the COM
Crawl :Enter the tap command, with the relay ''on'' and ''off'' after 600 ms
Auto-lock :Enter the self-lock command, the relay ''on'', enter the self-lock command again, the relay ''off'', and so on
delay :Input the delay command, the relay ''turns on'', after waiting for the set time, the relay ''turns off''; during the delay period, after the turn-off command is input, the relay turns off immediately
Slave address:A0-A5 are slave addresses, and 64 different slave addresses can be selected. In the MODBUS command mode, the slave address of the MODBUS command must be the same as the dial code of A0-A5 to communicate.
Refer to the ''N438C15 15-channel Modbus rtu Command''
Typical application
1.Control an individual module
2.MODBUS command mode (HEX), there are various control methods: serial port hyperterminal control (need to manually add CRC check code), Modbus Poll software control (software automatically adds CRC check code), PLC or microcontroller program control
