Logic Gates with Logic Machine FB Editor - vmic - 23.11.2022

Hi
I would like to create a logic schedule like in the photo I am sending (its from a LOGO! Soft Comfort example I made for this schedule). 
What I need to make is when the last room thermostat is getting close I need on electrovalalve to stay oppened so I will create a by pass hydraylic system for the water to avoid much pressure in the water circuit.
How I am going to do it in FB editor cause as far as I can see there is no NAND gate inside editor.
Can you please help me withis issue?

BR

RE: Logic Gates with Logic Machine FB Editor - Daniel - 23.11.2022

I added nor function to the universal gate script. Resident scrpt 0 interval and tag your inputs sctipt and fill the table
Code:
if not client then
  -- each group has 3 fields:
  -- tag - status object tag
  -- output - status output object
  -- mode - calculate mode (and/or/avg/nor)
  groups = {
   
    { tag = 'nor1', output = '0/0/8', mode = 'nor' },
   
  }

  -- time to wait between last telegram from any status in group and update
  updatedelay = 0.5

  -- object value cache
  values = {}

  -- object datatype cache
  datatypes = {}

  -- send update only when value changes
  grp.checkupdate = function(alias, value)
    if values[ alias ] ~= value then
      grp.update(alias, value)
    end
  end

  calc = {}

  -- AVERAGE value
  calc['avg'] = function(group)
    local result, count, value = 0, 0

    for _, address in ipairs(group.objects) do
      value = values[ address ]

      -- number must be in [0..100] range
      if type(value) == 'number' then
        result = result + value
        count = count + 1
      -- boolean true is 100%, false is 0%
      elseif type(value) == 'boolean' then
        if toboolean(value) then
          result = result + 100
        end

        count = count + 1
      end
    end

    if count > 0 then
      result = math.floor(result / count + 0.5)
      grp.checkupdate(group.output, result)
    end
  end

  -- AND gate
  calc['and'] = function(group)
    local result = true

RE: Logic Gates with Logic Machine FB Editor - vmic - 24.11.2022

Hi and thank you for your answer.
Beacuse I am not very familiar with scripting is it another way to do it or can you please explain me how is this going to be executed?
Thank you in advance

RE: Logic Gates with Logic Machine FB Editor - Daniel - 24.11.2022

There is no need for any scripting here. Just copy whole script to a resident one and fill the table in line 8. tag is the tag name which you should add to all input objects you want to monitor. output is the group address to you want to write result. mode no need to change, You can use same script for other logics as described.

Hi! 
I just created a new scripting to a resident one as you can see in the photo image and I filled the line in table 8 . I changed the name in the tag place (tag name) but whre all the other inputs are ?
And how I am going to test it to my office like a simulation if it's working or not?

RE: Logic Gates with Logic Machine FB Editor - Daniel - 25.11.2022

Go to objects and find your input object and click on it. You will see one of the fields Tag, type there nor1
   
Do the same of all other input objects but NOT output.

Go to your resident script and delete it! 
Now create new one and paste my script again.
Change 0/0/8 to 0/0/1 (I'm guessing this is your output object)
Save, just in case disable the script and enable again.
You can simply test it by changing manually values of the input objects and monitor the output.  You do it in object tab.

RE: Logic Gates with Logic Machine FB Editor - vmic - 26.11.2022

Hi thank you for your answer
We made another Logo project cause I have been told that when the specific electrovalve mains open then automatically the heatpump must turn to Off cause we don't want heated water pass through just water in a normal temperature.
So we made this Logic diagram

How will this look when min/max/avg

RE: Logic Gates with Logic Machine FB Editor - admin - 12.12.2022

Average is already implemented, for min/max add these functions before -- prepare each group
Code:
-- MAX value
calc['max'] = function(group)
  local result = -math.huge

  for _, address in ipairs(group.objects) do
    local value = values[ address ]

    if type(value) == 'number' then
      result = math.max(result, value)
    end
  end

  grp.checkupdate(group.output, result)
end

-- MIN value
calc['min'] = function(group)
  local result = math.huge

  for _, address in ipairs(group.objects) do
    local value = values[ address ]

    if type(value) == 'number' then
      result = math.min(result, value)
    end
  end

  grp.checkupdate(group.output, result)
end

Add mapping like this:
Code:
  groups = {
    { tag = 'nor1', output = '0/0/8', mode = 'nor' },
    { tag = 'avg1', output = '0/0/1', mode = 'avg' },
    { tag = 'min1', output = '0/0/2', mode = 'min' },
    { tag = 'max1', output = '0/0/3', mode = 'max' },
  }
