плк-150 и Rs232

[zobza]

Добрый день. Занимаюсь разработкой с использование ПЛК-150, а именно передачей необходимой информации по RS232. Использовал библиотеки SysLibCom и UNM. Порт сканируется с помощью PortMon. Так хотелось бы узнать почему в порт присылается не только отправленное сообщение но и всякий "мусор"?

проект в студию. никакого мусора быть не должно.

PROGRAM PLC_PRG
VAR
str:STRING:='hello';
END_VAR

LockDevice(0);
SetByte(0,str,LEN(str));
ReleaseDevice(0);

Считывается:
11:28:28 Gateway.exe IRP_MJ_READ Serial0 SUCCESS Length 122: ..D...X.....................C............hello.... ..............

11:28:29 Gateway.exe IRP_MJ_READ Serial0 SUCCESS Length 122: ..D...".....................C............hello.... ..............

PROGRAM PLC_PRG
VAR
dwPortHandle: DWORD;
comset: COMSETTINGS;
port: PORTS := COM1;
str:STRING:='AT$R$N';
END_VAR


dwPortHandle:=SysComOpen(port);
comset.byParity:=0;
comset.byStopBits:=0;
comset.dwBaudRate:=9600;
comset.dwBufferSize:=0;
comset.dwScan:=0;
comset.dwTimeout:=0;
comset.Port:=port;
SysComSetSettings(dwPortHandle,ADR(comset));
SysComWrite(dwPortHandle,ADR(str),LEN(str),0);


11:38:35 Gateway.exe IRP_MJ_READ Serial0 SUCCESS Length 120: ..D...I..............%.................AT......... .............

Правда есть предположение что это не считываеться не только то что отправляет ПЛК, но и какая то служебная информация. И еще после ресета гипертерминал выда

При старте есть лог на 232.
11:38:35 Gateway.exe IRP_MJ_READ Serial0 SUCCESS Length 120: ..D...I..............%.................AT......... .............
А что такое Gateway.exe? Это среда разработки, к-я связывается с ПЛК по тому-же порту в то-же время?
Тогда ясно откуда в канале связи есть "посторонние" символы.

К сожалению ничего не ясно. При создании простого проекта без использования 232-ого типа ";" на COM-порте все чисто. И еще вопрос, почему сообщение начинает посылаться на порт до того как происходит нажатие Start. Тоесть я только запрограмировал ПЛК, не успел нажать Start, а он уже присылает сообщение.

[Филоненко Владислав]

Потому что Gateway.exe . Используйте для связи с ПЛК Ethernet.
