Hezký den,

potřeboval bych poradit, jak přes modus zapínat relé. Mám Neuron a na něj napojenou Sx40 s relé výstupy. Něco z toho čtu, i když mi není jasná ta hodnota na asi třetím registru. Vše by mělo být vypnuté.

Tedy otázka, jak nastavit ty modbus bloky, abych poznal v jakém jsou relátka stavu a jakou hodnotu do nich posílat, abych je zapnul a pak zase vypnul.

Díky moc.

Lukáš L.

Dobrý den,

nainstaloval jsem node red obraz z webu unipi. node red funguje. Zkusil jsem i instalovat přes bash podle tutorialu zde EVOK https://evok.readthedocs.io/en/stable/#__tabbed_1_2

Ale prosetě na IP_Adresa:80 mi to v safari hlásí že adresa není validní a že ji nemůže otevřít. Před ip adresu se také vždy automaticky vloží "www."
má to tvar "www.192.168.1.xxx"

Předpokládám, že EVOK jede, jen nejede ten webový. Jde nějak rozjet?
Zkusil jsem i toto, ale bez úspěchu:"apt install -y evok-web"

Díky

Lukáš

Re: Evok brings 404 Error

Hello,

do you have any tutorial how I can connect two Neurons?

If I will create one project in Mervis, can I add two Neurons into project and can I read digital inputs from first Neuron and setup rele output on second Neuron?

Thank you

Lukas

Thank you Tomas, it was very helpful. Now it working. I only switch off parity on external modules and communication started :-)

Parity is pin 8? I will try it. What is better? Parity no or yes?

Thank You

i think I have all setted. I changed address on the extensions, restart extension, upload program and it dont work.

Hi do you have some manual how I can connect more Modbus extensions? I have xS40 and it works fine with my M303. But when I connect another xS40 I cannot connect it via Modbus. There is no connection. I try sett up addresses on pins, setup Mervis, but LED diodes for connection are off.

Hi,

I have Neuron M303 and xS40 and anything on xS40 don't work. I have directly connected DI from M303 to DO from xS40, but it is always off. (DO from M303 work fine)

I have the modules connected via Modbus RS485.

I tried set DO on xS40 in Mervis to true, but it still off.

Can I read online the status of DI or DO in Mervis? Or with some tool? Or if the Modbus work?

Thank You

Lukas

Hi,

I am solving same issue. I have ST program. Its reacts only on rising edge. But it is slowly and it not work on every push though I have sleep ratio 5%.

PROGRAM tlacitko
	VAR_INPUT
		tlacitko:BOOL;
	END_VAR
	VAR_OUTPUT
		rele:BOOL;
	END_VAR

if (tlacitko=1 AND rele=1)
THEN
	rele:=0;
ELSIF (tlacitko=1 and rele=0) THEN
	rele:=1;
ELSE
;
	
END_IF;

END_PROGRAM
