2 byte error message - Krstfr2k - 08.11.2017
Hello (again)!
I have a UK24EIB Gateway which has a 2byte error message for each MP-Address.
Error codes for High-Byte:
0b0000’0000 = No error present
0b0000’0001 = Connected actuator does not correspond to parameterised type
0b0000’0010 = No communication possible at this address
0b0000’0100 = Connected actuator signalling error, see Low-Byte
0b0000’1000 = No valid Min / Max values
0b0001’0000 = Non-Hall sensor motor actuators only: Actuator not yet synchronised
0b0010’0000 = Test run active
0b0100’0000 = Monitoring time of reference value elapsed
0b1000’0000 = Not used Several errors can be present together, OR-gated bitwise
Error codes for Low-Byte:
0b0000’0000 = No error present
0b0000’0001 = Stop & Go ratio
0b0000’0010 = Increased position travel
0b0000’0100 = Overload, reference position not attained
0b0000’1000 = No support at present
The first 4 Bits are always 0. Several errors can be present together, OR-gated bitwise
Is there a way to present these values in visualization?

Hi,
Use function getbit() from this post:

It can also be done like this, but if you have several error messages the resulting string can be too large (string type is limited to 250 characters).
Code:
value = event.getvalue()
-- table key is bit number starting from 0
errors = {
[0] = 'Stop & Go ratio ',
[1] = 'Increased position travel ',
[2] = 'Overload, reference position not attained ',
[3] = 'No support at present',
[8] = 'Connected actuator does not correspond to parameterised type',
[9] = 'No communication possible at this address',
[10] = 'Connected actuator signalling error, see Low-Byte',
[11] = 'No valid Min / Max values',
[12] = 'Non-Hall sensor motor actuators only: Actuator not yet synchronised',
[13] = 'Test run active',
[14] = 'Monitoring time of reference value elapsed',
}
result = {}
for i = 0, 15 do
mask = bit.lshift(1, i)
if bit.band(mask, value) ~= 0 then
if errors[ i ] then
table.insert(result, errors[ i ])
end
end
end
text = table.concat(result, '; ')
grp.update('1/1/1', text)You can also make it multi-line by replacing '; ' in table.concat with '\n', but then you need some extra CSS:
Set "Additional classes" of your text object to "multiline" (without quotes) in Visualization editor.
Add to Custom CSS (Vis. graphics > Edit custom CSS)
.multiline {
white-space: pre;
text-align: left;
}

Thank you so much for the help, exactly what I was looking for!
