[Octave-patch-tracker] [patch #8263] Instrument control package: add modbus capabilities

[Stefan Mahr]

Follow-up Comment #1, patch #8263 (project octave):

Just looked to the code. It's a very low level interface to libmodbus. I would
prefer a more high level interface, similar to the existing interfaces with
own data type.

For example:

a = modbus('192.168.1.1','tcp'); % to create a new type, using tcp in this
case
fopen(a);  % allocate resource and connect (modbus_new_tcp, modbus_connect)

fflush(a); % (modbus_flush)

fprintf/fwrite(a,bits); % read/write bits
fread(a,bits);

get(a,'registers');              % reading/writing registers
set(a,'registers',registerset);

fclose(a); % close modbus (modbus_close, modbus_free)

clear(a); % clears variable from memory (and closes it if not done with
fclose)


I've never worked with modbus yet, so what's your opinion? Does it make
sense?
