3-2 Output modes
The F3EM2 light curtain can provide various output modes and combination of these to
describe the position and the size of an object:
Example:
In serial operation F3EM2 can transmit status of each single beam or a combination of two
output values. See 3 examples how this is reflected for each function:
Examples:
Specification and settings of each function and the serial protocol configuration are described
in chapter 5 ’Operating serial output models (RS-232C)’ on page 5-1.
