2.6 Transferring data

2-120 SIMATIC A&D DataManagement Client - 07/2011

ADDM uses the serial coupling to all SIMATIC OPs. These devices generally have

the RS-232 interface on board. The date transfer speed depends to a great extent

upon the industrial environment and upon the quality of the cable used.

The serial coupling (component) can also be used for backing up older

SINUMERIK controls or non-Siemens systems. The data must be transferred in

several packets, depending upon the parameterization of the control. If the control

permits all the data to be output at once, ADDM can store this in a file and can

transfer it back to the control in case of disaster recovery.

LPT1 parallel port

The parallel port is one of the standard interfaces of a PC, however, under certain

circumstances, it may no longer be possible to fit this interface into newer PCs. The

interface is also frequently referred to as the Centronics interface because this

interface, which was named after a printer manufacturer, became a worldwide

standard. This interface transfers a byte in parallel and thus offers the opportunity

of transferring data significantly faster than is possible with the serial interface.

The DOS drivers, Interlnk and Intersvr provide the option of coupling two PCs by

means of a parallel null modem cable between their LPT1 ports. In this case, one

PC is driven as host (Intersvr) and the second PC as client (Interlnk). In the client,

the drives of the host are shown as removable data carriers. This enables simple

data exchange by direct access. The use of these drivers is subject to the licensing

agreement from Microsoft and their function is subject to additional conditions. For

example, it is technically impossible to use these drivers with the WINDOWS NT

operating system.

Interlink drivers

You need the Interlink drivers: INTERLNK.EXE and INTERSVR.EXE in order to

activate the Interlink connection. These drivers are stored in a directory on the PC

(e.g. C:\OLDDOS). The CONFIG.SYS file must now contain the following entry:

DEVICE:=C:\OLDDOS\INTERLNK.EXE

This loads the driver into the PC"s memory during boot up. If the PC is connected

to another PC via a parallel cable, and this PC runs as host ("INTERSVR.EXE"

started), the two PCs link up automatically. The first three drives of the host are

linked.

Note

It is important that the drives linked via Interlink are FAT16 drives. The data

transfer does not function correctly with other formats.
