Hi Martin
I follow the suggestion to set autogen only on needed variables (just DI and DO_w).
I solved the issue.
thanks

Hi all
I need to add a second Patron PLC (m207) to my project and need to pass the DI and RO from one to another.
I think the only possibility is trough SSCP protocol.
Can you provide some documentation on how to use?
There is the possibility to have only one HMI interface to interact with the 2 PLC?

Hi team,
some years ago I implemented my project with Neuron+Mervis with no issue.

Now I'm starting a new project and I see the Patron line is available and also there Mervis is an option.

Which is your suggestion for this new project? which of 2 (Neuron vs Patron) has higher planned longevity?

thanks
antonio

Thanks Martin
now it's clear and working.
Antonio

@Martin-Kudláček said in node red istance to be interfaced to Mervis PLC:

face from the Node-RED, but we don't have any Node-RED nodes tested

Thanks Martin,
how to spin Modbus TCP on Mervis?
Antonio

Hi all,
I have a stable Mervis environment with Neuron + several extension. I want use a dedicated node red instance on dedicated HW and finding a way to interface it with Mevis. There is way to read and write Mervis Global Varialbles trough Modus TCP/IP?
Thanks
Antonio

let me add the screenshot from Mervis Debug showing the 4 DI variable in red status.

Hi all,
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.

Re: How to set CONTROLLERTYPE to heating

Hi Martin
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.

I Tried

PROGRAM B31_TEST
VAR IN1, IN2:REAL;
O1: BOOL;
FB: LIB.CORE.V1_0.B31_REVERSE_ON_OFF_CONTROL_SEQUENCE;
END_VAR
FB(X:=IN1,CONTROLLERTYPE:=COOLING, W:= IN2);
O1:= FB.OUT;
END_PROGRAM

but
i get the error "can not find the object 'COOLING' in the current context"

Hi all,
for my project i need to simulate a variable resistor controllable in some manner with Neuron.
Do someone has some idea on how to do?
thanks
Antonio

Hi Team,
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:
varname (CONTROLLERTYPE:=heating);
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?

thanks
Antonio
