Glossary

Ethernet

Local network (bus structure) for text and data communication with a transfer rate of 10 Mbps.

Formatting

Basic partitioning of memory space on a magnetic data carrier into track and segments. Formatting deletes all data on a data carrier. All data carriers must be formatted prior to their first use.

Gender changer

Using the gender changer (25-pin / 25-pin), the COM1/V24/AG port of the SIMATIC PC family can be converted to the usual 25-pin male connector.

Hard disks

Hard disks represent a form of magnetic disk storage medium (Winchester drives, hard disks) with integrated magnetic disks.

Hub

A term in network technology. In a network, a device joining communication lines at a central location, providing a common connection to all devices on the network.

Image

This is refers to the image, for example, of hard disk partitions saved to a file in order to restore them when necessary.

Interface

see Interface

Interface, MPI

MPI is the programming interface of SIMATIC S7/M7. Allows central access to programmable modules, text-based displays and OPs. The MPI nodes can intercommunicate.

Interface, parallel

Information is transmitted byte for byte via a parallel interface (port). This means that the transmission rate is very fast. The PGs/PCs have one parallel interface (LPT1).

Interfaces

The connection between individual hardware elements such as PLCs, programming devices, printers or monitors via physical connections (cables).
