| 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 established and possibly the parameters of the serial port were queried. |
| Serial Serial Line Redundant System&Line Redundant | The serial port was open and the required serial port parameters were set. |
| SerialOverUDP Device Redundant SerialOverUDP Line Redundant SerialOverUDP System&Line Redundant | Binding to the specified local UDP port(s) was successful. |
| TCP/IP-TCP TCP/IP-TCP Redundant TCP/IP-TCP System Redundant | A TCP connection was established (client protocols), resp. binding to the specified local TCP port(s) was successful (server protocols). |
| TCP/IP-UDP | Binding to the specified local UDP port was successful. |

- Line category SerialOverUDP Line Redundant: the FA - FB flags inform about a communication failure on the primary/secondary line.
- Line category SerialOverUDP System&Line Redundant and TCP/IP-TCP System Redundant: the FA - FD flags inform about a communication failure on the primary/secondary line of the A/B system.
- Line category RFC2217 Client: flags inform about connection to the specified IP address (FA - 1st address, FB - 2nd address, etc).
- Line category TCP/IP-TCP and communication protocol IEC 870-5-104 Server: flags inform about connected clients. For a detailed description see the note in the description of the protocol.
- Line category TCP/IP-TCP or TCP/IP-TCP Redundant and multiple client communication protocols (e.g. IEC 870-5-104, MODBUS Client, DLMS/COSEM, Siemens SAPHIR): flags inform about connection to the specified IP address (FA - 1st address, FB - 2nd address, etc).
Note: the Siemens SIMATIC S7 ISO on TCP communication protocol does not have such diagnostics, as it can create up to 4 TCP connections in parallel.
