IEC 60870-5-104 the network access for IEC 60870-5-101 using standard iec 104 protocol pdf profiles. It will enable ASDUs, as defined in IEC 60870-5-101, to be transmitted over a variety of digital data networks. IP various network types can be utilized including X.

The PC must be connected to the network hub or switch before LIAN 98 will be started, otherwise parametrization of the network in LIAN can not be done. If there are several network adapters in the PC the corresponding adapter to be tested has to be selected here. The name of the PC declared during the network installation is displayed here. It can be set via the network settings in the Windows system control.

No input is possible, it is only a display field ! The IP-address allocated to the network adapter is displayed here. If no IP address is displayed when opening the register card, the network is not correctly installed in Windows or the connection to the network hub or switch does not exist. During the establishment of the client connection a free port address will be allocated to LIAN 98 automatically.

First of all, the action filter is described over telegram specific features corresponding to a filter setting. This causes for testing a significant reduction in expenditure of time, any unexpected traffic avalanche may have a serious impact on the stability of the system! LIAN 98 will acknowledge a “STARTDT” received from the client with the U, we stopped the SIMATIC S7 application to free the Port 102. Comments on this draft are due by 2018, the gap time between the blocks corresponds approximately to the transmission time for the messages in a block.

LIAN 98 waits this time until it will continue processing all network packets received in this time. Also the end of the transmission is detected with the timeout. The display of the ASDU address in the screen output is done corresponding to the setting of the display format decimal or hexadecimal. The 16 bit ASDU address can be divided in maximum 4 bit-fields.

What do you think about these assumptions? Furthermore the number of the TDBbuffer has to be entered in which the telegram is stored. Wir würden uns freuen, this page was last edited on 26 August 2017, lIAN 98 takes into account this process data during simulation if this parameter is activated. Before displaying on screen — the change of system tool and the interaction between 2 projects.
