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

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

Re: Button to light

Hi,

is there some possibility to set sleep ration for NEURON? I was set up in UniPi, but in Mervis project with NEURON there is not the same choices for it.

Thank You

Hi Tomas,

do you have some presumed date?

I have DI in one box and 240V in another. And I need some rele board for lights. Can I use UniPi as Modbus slave and control it from NEURON?

Thank You
