Scripting bug: Error reading time value from global with custom formatting

Trystan Williams — Mon, 13 Dec 2021 23:59:20 +0000

-Create new Global of type Time with name Mash Rest 1
-Set value to 30 minutes
-Read from script with

new time rest1
rest1 = "Mash Rest 1" value

Result -> OK

-Edit Global to use a custom format of mm:ss
-Re-run script

Result -> Error: Expected a Time type

HERMS Brewery Script

Is anyone using a script to run a HERMS three kettle system?

Colors

Jason — Sun, 17 Nov 2019 13:13:59 +0000

I believe the answer is no, but wanted to double check... Are an element's color attributes reachable by script? For example, if I use a Global as a mechanism to display a status, can I alternate between a red/green background color as status conditions warrant?

Thanks!!

Object ref error

Hi, I'm stuck again. I was writing a script to do a boil for an hour so I could calibrate my boil off rate. It's my first script and it was working good until I got to the point that I wanted to do something when the temperature reached a certain point.

I borrowed from your post "Brewery Code" here in the Scripts section of this forum. I noticed that it was hanging on my wait statement even though the condition was true. I dumbed it down to a little test script here and it is still doing the same thing.

I have a 1-Wire temp sensor called "Boil Kettle Temp". In my test here, I can assign it to a local variable and you can see that it properly evaluates to 202.1. The next line down though when I'm trying to use the same thing in a wait statement like you had done in your script, it errors out with an object reference error.

Where am I going wrong?! This is on version 1.1 Build 4.

Thank you!

Jason

A portion of your script:

wait "Boil Temp" Value >= 210
Status = "Boil"

My test script:


new value testTemp

testTemp = "Boil Kettle Temp" Value
wait "Boil Kettle Temp" Value >= 200
testTemp = 0

Date/time manipulation in v1.1

pbruno3 — Wed, 01 May 2019 00:32:09 +0000

I received a couple of questions about date/time manipulation, so wanted to post up a sample that may shed some light. In this "Test" script example, we define a date/time variable named 'trigger', assign it to a date/time, then print it (to the Output tab). We then define a time variable 'change', and make it one hour. We then define another date/time, and add the 'change' time variable to it, then print it. Finally, we compare the two date/time variables and generate a print out as a result (will always resolve to "Yes" here).

If you wanted to do a comparison to the current time, use the intrinsic 'now' variable (for example: trigger = now). Also, if you wanted to add days rather than hours, you can include days in the time variable (for example: change = 1:00:00:00).

Hopefully this sheds some light. Please let us know if you have any questions, issues, or concerns!

new datetime trigger
trigger = "04-30-2019 10:00:00 PM"
print trigger

new time change
change = 1:00:00
new datetime future
future = trigger + change
print future

if future > trigger
print "Yes"
else
print "Nope"
endif

stop "Test"

Temperature Conversions

Piggles22 — Sun, 24 Mar 2019 15:55:28 +0000

The BC manual mentions temperature conversions (C to F and F to C) for RTD's on page 51 but doesn't give any detail on how to do the conversion. What am I missing here? I'm just trying to convert RTD input data from C to F.

Using Global DateTime

dgough — Sun, 10 Mar 2019 19:41:02 +0000

I am trying to compare two Global DateTime values and the syntax I'm using isn't working.

Example:

wait G_TimeDate value >= A_StartTime
LED state = on
sleep 1000
goto loop

This is the error i get:

Rounding or Truncating Math Calculations

Piggles22 — Wed, 06 Mar 2019 21:31:54 +0000

Is there a script function or method to either round or truncate math calculations to a fixed number of digits to the right of the decimal point. For example, if I want to calculate and display my grist ratio as a variable in a workspace, I only need to see it displayed on screen to 2 or 3 decimals but it currently displays up to 12 digits to the right of the decimal point depending on the values I enter for mash volume and grain weight.

'For' statement?

clearwaterbrewer — Sun, 03 Mar 2019 13:52:17 +0000

Is there a 'for' statement in the scripting language?

for i = 1 to 9

related - can I do something like:

"PID 1" Kp = "PID 1" Kp value + .01

multiple elements - variable power via script and pseudo A-D conversion

clearwaterbrewer — Wed, 20 Feb 2019 20:01:33 +0000

I would like to control power with contactors, as heat generation from SSR's for the power level I am using is excessive... 45kw

5x 9kw 3-phase elements controlled by 6 contactors

C1-c4 - 9kw

C5 - 6kw

C6 - 3kw

with this, I should be able to get 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45kw

Control would be via an analog input on the Mega , could be potentiometer or any analog signal. Could even be a PID PWM through an analog board back into the Arduino.

wondering what the best approach is?

here is one idea:


if "analog_0" value < 15
 // zero power
 "C1" state = off
 "C2" state = off
 "C3" state = off
 "C4" state = off
 "C5" state = off
 "C6" state = off
elseif "analog_0" value < 31
 // 3kw
 "C1" state = off
 "C2" state = off
 "C3" state = off
 "C4" state = off
 "C5" state = off
 "C6" state = on
...
...
...
elseif "analog_0" value < 239
// 42kw
 "C1" state = on
 "C2" state = on
 "C3" state = on
 "C4" state = on
 "C5" state = on
 "C6" state = off 
elseif "analog_0" value >= 239
 // 45kw
 "C1" state = on
 "C2" state = on
 "C3" state = on
 "C4" state = on
 "C5" state = on
 "C6" state = on
endif 
sleep 10000 // 10 seconds between power changes
goto PowerLoop
