This command executes the process teach colour or a scan colour range.
INFORMATION
Both the teach-in and scanning process consist of a command sequence which must be
executed so that the sensor can be ready for use.
Teach-in process
Step 1:
Bit 0 = 1 Start „teach colour" (command „0x58"): The sensor learns the current colour for a short
period. The following command may follow after 2 ms at the earliest.
Step 2:
Optionally, new tolerance values can be selected, (command „0x49"). The teach-in function via
control key also writes these tolerance values. If no tolerance is written, the last selected tolerance
(via keys or command telegram) is used.
Step 3:
Bit 0 = End „teach colour" (command „0x58").
Scanning process
Step 1:
Bit 1 = Start „Scan" (command „0x58"): The sensor starts the scanning process.
Step 2:
Bit 1 = End „Scan" (command „0x58"): The sensor ends the scanning process.
The minimum duration between start and end is 2ms. If the duration is less, the scanning process is
abandoned.
