This command delays the response times according Operation manual (Part No. 104 906 Chapter 11.2)
•
Note: This command can not distinguish between all beams interrupted and a light curtain failure. Use command 0x08 to
verify the response! Use command (100 [64 Hex]) instead.
2.2.5.17.
Get zone status (40 [28 Hex])
This command is a simple way to get the status of a certain zone. The zone can be defined by setting a first
beam and last beam (inclusive).

* This command delays the response times according Operation manual (Part No. 104 906 Chapter 11.2)
Note: Beam numbers for a zone are inclusive
Example: Byte 3 = 10, Byte 4 = 15 -> Beam 10-15 (inclusive) considered
2.2.5.18.
Get parameter value (42 [2A Hex])
The command is used to read out a parameter (Table 19) from the ObjectC 100. The parameter can be set with
command 28 (2.2.5.11).
