Hy!
I read out a controller of a BergerLahr axles via RS232 (with an "RS232 to RS485" adapter) and I
use the "Modbus" protocol to do this task.
Everything works fine, but the readout rate is too slow... I am only able to achieve a rate
of approx. 10-15Hz to get the data.
Is there a possibility to boost the readout value ... (the more the better)?

Hey
Thank you for your help... I managed it to find out the addresses... there
is a software tool which handles all the parameters of the axle and in this tool
there are all the addresses included.
Is there any VI in which I only have to put in the addresses and everything works?
Greetings!

Hy @ all!
I want to control a axle from Berger Lahr (Schneider Electric) with Modbus under
the environment LabView 8.20
Unitl now I have tried a lot to make the thing work...
http://zone.ni.com/devzone/cda/tut/p/id/4722
... use the Modbus library respectively
http://zone.ni.com/devzone/cda/epd/p/id/4756
Because of the fact that I am a greenhorn in connection with "Modbus", I am not sure how to
make the axle work, which busregisters I should use, ...
These are the files which are improtant for the task:
The VI (Attachment)
modbus.vi
The Modbuslibrary
ftp://ftp.ni.com/pub/devzone/epd/nimodbus.llb
The Modbus Manual of the Axle/Contoller

I really hope, that you are able to help me
Thank you for your time

Hallo Ihr!
Ich m
Faster readout of data through COM Port (Modbus)
in LabVIEW General
Posted
Hey!
In connection with LabView Support we managed it to "boost" the thing... now it is possible that I am able to get data each 10ms (more than 15x faster)... so my measurement is a lot faster than before. (A "Wait" command was adjusted in the modbuslib, so that an important part of the VI runs every 1ms instead of 10ms)
Thank you for your help!
