Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
I'm playing with and I XSCADA problem arose when finished ... program it does not work ... Usually use software-controlled communication, but in this case, as I wanted to meet other microcontroller functions, preferably do control communication hardware ... It's where I start my problem that did not work and I read several topics and I could not take it forward to the project ....
We split.

The editor of scada, can handle multiple communication protocols.
Ascii Protokol :
Send String Via RS232
[1;1;W;40] Format : [DeviceAdres;RegAdres;Write;Value]
Receive String Via RS232
[1;1;W;40] Format : [DeviceAdres;RegAdres;Read;Value]
In my case, configure the different entries in different variables (addresses) to control the functions ... For example, to control the analog voltmeter and ammeter, select the Address List 1 and 2 ($ 1 - $ 2) ...
I mean, from the pic would have to send
[1,1, W, adc value Volts] and [1,2, W, Amp adc value].
This same action, but with different addresses can complete them with the various functions of the software, but when run proteus and scada, and does not work in proteus rs-232 terminal, you see the error indicator ...

I help to find the problem that really do not understand?
No if I firewall blocks port ...
not if I am misusing HSERIN and HSEROUT ...
or, is some small error

is not the same as code
Code:
HSEROUt ["[1;1;W;",dec AUX_TX1,13] ;envio adc volts
HSEROUt ["1;1;W;",dec AUX_TX1,13] ;envio adc volts
should be
HSEROUT [1,1,W,dec AUX_TX1,13] 'envio adc volts
I think?
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
SERIALIN interrupt subroutine has 1 RESUME and 2 RETURNs, not sure that will work as expected.
PBP interrupts are "special". Darrel's interrupt routines are much more reliable and easy to use.

changing those lines and did not work ... adding the probe in the "" W because that indicates if write or read and not have problems ... both to receive and send packets to the serial port ... .
with serine and serout probe to see if it was a problem that the port is blocked and apparently, that's another mistake more than I have in this example.
I'll investigate the issue of ports to get me doubt ...

Robert, see, you could guide me in those breaks you mention?
sorry for my spanglish :D

Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
Well! I found a problem and already almost solved ... this port is blocked, so use a virtual port for nesting
Attachment 7352
but now I see communication by the hyper terminal, note that there is a speed problem, so I do not recognize the package and data ... this is the catch:
Attachment 7353
test at a lower bauderate OR CHANGE PARITY? in this case as set HSERIN and HSEROUT to work at another speed? I think part of the problem here ... sure then continues with the theme of interruptions
settings was 8n1 9600 for both applications

Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
:D ready .... one less problem ... I haven´t configured in the hyperterminal as reversed polarity
now continue with the rest to see and understand that the package is not interpretedAttachment 7355
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
I struck me ... I'm locked ... I get angry that I can not take this issue forward ... I turned round and round and do not understand where is the error ... Copy and paste them as examples to work and backed away more , what progress, because now I understand much less than before the function HSERIN / HSEROUT ...
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
Do you have a logic probe to see exactly what is transmitted?

Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
Hello friend; It was first tested in a virtual version (Proteus + + Xscada Virtual Serial Port Driver).
Xscaa brings a tool to read the data packet that enters and exits the ports ... you can write to them too.
Just went up a video capture as I can write to the port to see ... now check the link you gave me to wake neurons also see ...

Thanks for helping / bearings
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
A simulation can only detect what it is programmed to detect.
I'd love to afford one, but sometimes you have to build the real thing.
Robert
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
You're right; Tonight I will go to the board and I do physical tests ... take them it with serine and serout and once it achieves communication, shall pass to HSERIN / OUT ... I did not find any complete example in SanGoogle which guide me.
Tomorrow I commented as I was.
Re: Firewall win, or programmed wrong ... the problem is me? (HSERIN-PC)
I returned with news.
Well, we can say that there were many things which would not let me make the project.
On one hand, I had problems with the port of my PC, it crashes when more than one program wants to work with this.
On the other hand, although I could not make it work with HSERIN-OUT, accomplish it working with conventional serine and biggest mistake was in the way in which the variable sent ... In early attempts never included the "#". ..
Serout PORTC.6, T9600, ["[1,1, W,", # VOLT, "]"]
Another error in the first attempts, was the way in which the data expected. At first he was waiting at a specific point data and the program was obsolete (that is why I wanted to know how to use HSERIN-OUT, to do this to interrupt mode and keep the program running normal). The solution I found him, but only for short programs that do not have many instructions, is to use the following lines ...
SERIN PORTC.7,10,["[1,3,W,"],DATO
Interestingly, I can send a decimal variable and work it handles XSCADA to represent the analog graph.
Here's a simpler than video achieved so far, as you can understand HSERIN-OUT, an article for the community http://www.picbasic.co.uk in the section where my other two articles arme next:
