Neuron L203 DI not working
after one year of production working of one L203 with 8 extension module i need to report that some time I strange behavior very difficult to troubleshoot.
The last case was very schematic so i'm able to describe it.
Some DI of L203 (related so push button in my house) stop to work.
I used Mervis debug to see what was wrong and the only I see is that 4 DI of L203 are in FALSE state with red indication.
I don't think it's a software problem but seems an hardware problem.
This time the software reboot do not worked, only solution was a power off and on of L203.
Any suggestion how to solve those strange behavior?
They happen with very low frequency, initially they were once a month but now they are weekly.
Thanks for the support.
Set ControllerType input of B31_REVERSE_ON_OFF_CONTROL_SEQUENCE
I'm againg on the same topic after some months.
I'm not able to set (I'm using an ST program) the value of input "ControlType" of block B31_REVERSE_ON_OFF_CONTROL_SEQUENCE.
I search into help but there is no example of ST program that explain how to set the input.
VAR IN1, IN2:REAL;
FB(X:=IN1,CONTROLLERTYPE:=COOLING, W:= IN2);
i get the error "can not find the object 'COOLING' in the current context"
How to set CONTROLLERTYPE to heating
I'm developing an exec with ST.
I declare a var as "lib.core.V1_0.B31_Reverse_On_Off_Control_Sequence".
By default it is setted for cooling.
I'm trying to set for heating.
If I use like this:
during the build it return the error:
"Error Executables Exe_Termo ..... can not find the object 'heating' in the current context"
Can you explain how it work to set the CONTROLLERTYPE into ST?
Same RO at same time
I've several (total 4) blinds connect to different RO.
I use mervis to have a digital input that activate all the 4 RO at the same time.
Is it safe to activate several RO at the same time or do you suggest to have some delay? I could program so that after the DI the 4 RO are activated with some delay each other.
Let me know your suggestion.
RE: 1-Wire UTP cable color mapping
in my 1wire bus I've 3 HUB and several sensons. Everything is working fine.
Only problem appear when on the last port on my last hub I connected a rj45 splitter
( https://www.unipi.technology/1wire-hub-2-port-p50 ).
After a while I connect the thermometer to this hub it disconnect. (it appears red in mervis)
All RJ45 port are cabled whit pinout TIA-568B and thermometer are cabled as follow:
+VCC: blu + blu/white
GND: brown + green/white
1W : green + brown/white.
Do I need to use the same schema of connection on the thermometer atteched to 2 port splitter?
let me know if you have suggestion how to troubleshoot the problem.
