[Variable: not possible to see in online mode]

OK, they are costant value! Thanks a lot!

[Variable: not possible to see in online mode]

Hi,

the program that I show you is an unitronics example (MQTT). I notice that for the variable that have a "Power up" value,  is not possible to see the value in online mode! Is it normal? 

If yes, what does it mean?

[MQTT, the role of Unistream: Broker, server, client]

Not at all @Cara Bereck Levy

[MQTT, the role of Unistream: Broker, server, client]

Yes UniStream can only act as client. With the word server I can imagine that the plc is the client that  governs the system, reads values from some clients and writes other values to other MQTT clients.

[MQTT, the role of Unistream: Broker, server, client]

Hi,

I'm newbie of the MQTT protocol, I have reading something on internet for a new application with unistream and MQTT protocol.

On the help file I read: "UniStream supports MQTT as a 'client' that can both publish, and subscribe, to messages."

OK it's clear, so I nead of a local broker (for istance: a raspberry pi and mosquitto).

Then I try to study an example of unilogic software where I read: "UniStream can be configure to be a MQTT server."

So, what does it mean as "server"?

Thanks in advance.

[Remote Modbus TCP I/O]

Hi Flex,

I read this your post: http://forum.unitronics.com/topic/3318-problems-with-unistream-controller/

 

and Cara says that "UniStream supports more protocols and unlimited sockets…"

[Remote Modbus TCP I/O]

Hi,

I need to connect a USP-070-B10 Master(client) to 6 remote Modbus TCP I/O Slave (server) (http://www.moxa.com/doc/man/ioLogik_E1200_Series_QIG_v4.pdf).

Do I need 6 different socket? May be socket in Unistream are unlimited!!!

[Auto Tune with slow temperature control]

Is there chance of success with auto tune FB if the adjustment of temperature is very slow?

In a house the temperature variation is very slow, so it needs very time for autotune and may be that it does not work!

What do you think about it? I have to decide if use a plc or  more thermoregulators, one for each room.

[Unilogic installation 1_9 build 19]

Solved how?

Share your solution so others might benefit from it.

 

Thanks.

 

Of course!

Simply performed manual disinstallation the previous version and only then start the new installation!

Other time this operation was automatic.

Have we the same chance with UniStream series?

[clarification GPRS]

Simon, with Visilogic in Listen mode all work perfectly.

My dubt was born when you say:

 

>The IP address that the modem is given on the GPRS connection is usually a firewalled, private IP address, on its own subnet.

 

In this case I wouldn't able to ping modem IP. Instead I'm able!

[clarification GPRS]

>The IP address that the modem is given on the GPRS connection is usually a firewalled, private IP address, on its own subnet.

 

Is it possible to ping these IP address?

[clarification GPRS]

My be i understand!

May be you mean that with plc in listen mode it is no sure system! Everybody can connect to plc!

Can you confirm this?

[clarification GPRS]

In your example (V120_GPRS_sony_ericsson_wavecom.vlp) you write:

 

"However, in all GPRS applications, the PLC must initiate the GPRS data link by calling the PC."

 

Why this? There is the FB "Listen to Remote Device". If i understand well, with this FB PLC wait that someone call it.

 

So there are 2 possibility:

 

1) PC call PLC (PLC in Listen mode)

 

2) PLC call PC (PC in listen mode)

 

Do I missed some concept?

[Modbus TCP IP Communication with Siemens S7]

To use Modbus TCP with unitronics is very easy. With siemens the problem i a little more big. You must to buy cp341-1 and his driver (modbus). Total cost 1500 euro. I have performed this application some years ago and it si not very easy!

I advise you to buy a Operator Panel ( i use sitek) that work as bridge. You spend 400 euro and it is very very very easy!

Best regards
