Device setup

5.2 Interfaces

The LLB measuring system contains different interfaces. Measurement results and errors are signaled
at the outputs as described below.
Interface
The RS-232 is meant for the configuration of the device, however
RS-232
measurement can also be taken using the RS-232 interface. Measurement
results and/or error codes are sent corresponding to the command description.
To use this interface host system is needed as described in chapter 5.3.1
"Controlled mode" on page 104.
RS-422 The RS-422 operates like the RS-232, but it is an industrial interface and
therefore not only usable for configuration but also for controlled measurement
as described in 5.3.1 "Controlled mode" on page 104. The RS-422 can't be
used simultaneous with the SSI interface since it uses the same signal lines.
SSI Output The SSI Interface is only implemented in the LLB-500(F) type. The SSI
interface is updated after each successful measurement as well as after an
error occurs. If the interface is activated, it is updated in all operation modes.
Binary and Gray code as well as error signalization is supported. (See chapter
6.2.8 "SSI connection" on page 118)
The analog output is updated in controlled and stand-alone mode. It is
Analog Output
configurable and works with two ranges:
Digital Outputs Three digital outputs are included in the LLB measuring system. Two of them
are programmable, while the third is used to signal an error state of the device.
The digital outputs are updated in all operation modes.
