If a script error is detected in the run-time mode, an error text is written to the log "Script messages", and further execution of the script is terminated.
If some code of your script can return an error (for instance, a timestamp is incorrectly read out from a device, and this leads to an error while transforming that timestamp), place such a code in a separate function, and invoke that function in the protected mode, using the function pcall .
Example
function StrToTime(str) --transformation of a string to a timestamp
local str2=string.gsub (str, "%.", "-") --replace a dot by a hyphen in order to correspond to the format
local timeval=time.StringToTimeStamp(str2..".000"); --transformation to a timestamp
return timeval;
end;
function OnRead ()
NoErr,timeval=pcall(StrToTime,str1); --invocation of transformation function in the protected mode
if NoErr==true then
--there is no an error
else
--there is an error while executing
end
end
