Description
Permissible source addresses: 1
Without function, bit permanently set to 1
Permissible address range: 2
Without function, bit permanently set to 0
Length of the response telegram (number of data bytes + status
byte),
Value permanently at 5
Without function, bit permanently set to 0
The function identifier describes the action which is executed by the
BPS and answered:
90 (5A ) = Request position data
d h
91 (5B ) = Request one-time transmission of position data
d h
92 (5C ) = Activate positioning mode
d h
Without function, bit permanently set to 0
1 = No bar code decodable
0 = Bar code decodable
1 = Configured measurement range exceeded/undershot
(Measurement range default: 0 ... 10,000m, no negative values)
0 = Position values within the configured measurement range
00 = Reading quality > 75%
01 = Reading quality 75% ... 50%
10 = Reading quality 50% ... 25%
11 = Reading quality < 25%
These 4 bits contain coded diagnostic data
(see following description)
1 = Device is in Standby mode
(see request telegram)
0 = Device is in positioning mode
