File Information

MGCplus is a multichannel DAQ system by HBM. Many transducers / sensors are supported. With MGCplus, measurement data can be stored on a PC card harddisk. The file formats are *.me* and *.sto. With the utilities, these files can be loaded into MATLAB. The import leads to structured variables. Channel names, time information, units, scaling information and much more is available. Only the 4-Byte-INT (Intel) format is supported. Supported Time formats are:

(a) no time information,
(b) MGCplus device time,
(c) NTP time information.

From large files with the m-file meacomp a compressed "activitiy"-information ca ne derived. With help of "ginput.m" and the m-file cp42cut.m the interesting part can be read in.

Changes 1.03 -> 1.04
(1) Now, all the sample rates, from the slowest to the fastest, are support. The ids assignment matrix "wrat" has been expanded in all matlab m-files like "cp42mea.m", "cp42cut.m", "meacomp.m", "cp42sto.m" Changes Version 1.02 -> 1.03
Now, also the status of the measurement signals is evaluated. When measurement data is transferred in 4 Byte Integer Format, the least significant byte contains the status bits like state of Limit Value switches, channel error and overflow. The status of each measurement sample is contained in a new field called "status".
The M-Files "CP42MEA.M" and "CP42CUT.M" can read this information.
The status information can be displayed now in the graph window together with the measurement signal by the use of the M-File "plotmea.m". With an additional scalar input, the positions and/or the value of the status is shown additionaly.
New File: meastatus.m
meastatus extracts the change of status of measurement values.

Hi, that's what i am looking for. The documentation is also good, especially the format description of the mea files. Do you have something for simulink ?
I will put a post on my MGCplus FAN BLOG (

Great, this enables me to use MGCplus for DAQ on PC card harddisk and analyzing the collected data with MatLab (without the need to buy expensive DAQ programs)

New Version available:
Now, also the status of the measurement signals is evaluated. Measurement data in 4 Byte Integer Format contains also the status bits (state of Limit Value switches, channel error and overflow)
