Eurotherm Modbus RS232 Control



11 Jul 2009 (Updated )

Reads and writes information to Eurotherm controllers via Modbus RTU protocols.

function minTemp = tempobjreadmintemp(serialObject)
% TEMPOBJREADMINTEMP Reads minimum temperature from Eurotherm controllers
% minTemp = tempobjreadmintemp(serialObject) Reads minimum temperature in
% C from Eurotherm temperature controllers given an appropriate serial
% port object (generated from tempobj).

% e.g. minTemp = tempobjreadmintemp(tempobj(7)) - gives current minimum
% temperature from the device on COM7

% Range:

% serialObject = valid serial port object

% checks the number of arguments
error(nargchk(1, 1, nargin))

% retrieves information (tempobjcomm returns the temperature in C)
minTemp = tempobjcomm('readfullres', serialObject, 1, 112, 1);
