Protocol versions[ edit ] Versions of the Modbus protocol exist for serial port and for Ethernet and other protocols that support the Internet protocol suite. There are many variants of Modbus protocols:

Almost any modern personal computer has enough computational power to run the convolution in realtime without any problem.

Today there are many good, silent and compact PCs designed for multimedia usage which could be used to build a complete noiseless real time convolver with little effort. Of course to test the program you can also apply the correction off-line on audio files ripped from ordinary audio CDs, burning the corrected files on some fresh CDR and listening to them using a standard CD player.

A typical acoustic environment is a non minimum phase system, so in theory it cannot be inverted to get perfect compensation. Trying to get an almost perfect compensation for a given position usually leads to unacceptable results for positions which are even few millimeters apart from the corrected position.

The generation of a filter that provides good compensation of magnitude and phase of the frequency response of the direct sound, good control of the magnitude of the frequency response of the stationary field and an acceptable sensitivity on the listening position, requires many steps.

Here it is a brief summary of what DRC does: Initial windowing and normalization of the input impulse response. Initial dip limiting to prevent numerical instabilities during homomorphic deconvolution. Decomposition into minimum phase and excess phase components using homomorphic deconvolution.

Prefiltering of the minimum phase component with frequency dependent windowing. Frequency response dip limiting of the minimum phase component to prevent numerical instabilities during the inversion step.

Prefiltering of the excess phase component with frequency dependent windowing. Normalization and convolution of the preprocessed minimum phase and excess phase components optional starting from version 2. Impulse response inversion through least square techniques or fast deconvolution.

Optional computation of a psychoacoustic target response based on the magnitude response envelope of the corrected impulse response.

Frequency response peak limiting to prevent speaker and amplification overload. Ringing truncation with frequency dependent windowing to remove any unwanted excessive ringing caused by the inversion stage and the peak limiting stage.

Postfiltering to remove uncorrectable subsonic and ultrasonic bands and to provide the final target frequency response. Optional generation of a minimum phase version of the correction filter. Final optional test convolution of the correction filter with the input impulse response.

Almost each of these steps have configurable parameters and the optional capability to output intermediate results. There is a lot of psychoacoustic involved in the generation of room acoustic correction filters, so probably the use of a more psychoacoustic oriented procedure would give even better results.

Any suggestion with respect to this is appreciated. Within my HiFi system the application of the correction provides huge improvements.

By the way my system no longer can be considered a normal HiFi system. It is actually much closer to a studio monitoring system placed in a heavily damped room.

Furthermore there is also an high performance subwoofer, extending the response down into the infrasonic range, and everything has been tuned to provide the best results with the correction in place.The LOAD command loads data at the page level, bypasses trigger firing and logging, and delays constraint checking and index building until after the data is loaded into the Db2 table..

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in for use with its programmable logic controllers (PLCs).

Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices. The main reasons for the use of Modbus in the industrial environment are.
