Start / stop command is in the following bit format position: 000S 0000 0CCC CCCC
• C Sensor ID
• S 1 = Starts fast LED blinking
0 = Stops fast LED blinking
Data written has to specify a known Sensor ID.
Example: 0x1017 means “Start fast LED blinking of Sensor with ID 23”
• When Sensor is addressed correctly, common response will follow
• When the Sensor ID is not used in the system, and exception response with Modbus exception code
03h “Illegal data value” will follow. (If fast LED blinking was already active, it will be stopped)
Return to normal display content is possible by sending the stop command.
