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.
This is the program I wrote for a PIC16F877A
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
