An object of Line type can acquire the following values in D2000 system:
Object value | Description |
---|---|
True | The line is working. |
False | The line is not working. Note: Solving the line failure problems depends on the line category. Each line generates the output file called line_name.log placed in the subdirectory TRACE of the application directory. The file contains detailed information about the error. |
The definition of working of the line depends on its category:
Line category | Functioning line |
---|---|
LonWorks | The LonWorks dynamic library (ldv32.dll) was initialized and the specialized LON device could be opened. |
MOXA IP Serial Library | The Moxa dynamic library (Ipserial.dll) was initialized, a connection to the specified Moxa devices was established, and specified serial port parameters were set. |
RFC2217 Client | A TCP connection with the RFC2217 server was establish and possibly the parameters of the serial port were queried. |
Serial Serial Line Redundant System&Line Redundant | Podarilo sa otvoriť sériový port a nastaviť požadované parametre sériového portu. The serial port and set the required serial port parameters. |
SerialOverUDP Device Redundant SerialOverUDP Line Redundant SerialOverUDP System&Line Redundant | Podarilo sa obsadiť (bind) špecifikovaný lokálny UDP port (porty). |
TCP/IP-TCP TCP/IP-TCP Redundant | Podarilo sa nadviazať TCP spojenie (klientské protokoly), resp. podarilo sa obsadiť (bind) špecifkovaný lokálny port (serverovské protokoly). |
TCP/IP-UDP | Podarilo sa obsadiť (bind) špecifikovaný lokálny UDP port. |
Poznámka:
Object value of category Communication lines can have set also the flags (user attributes). Currently they are implemented for following combinations of line categories and communication protocols:
