Equipment Description
Specified Cables The cables are specified by category depending on their transmission and high- frequency properties as follows:
Category | Specification | Approved |
|
|
|
1 | - | No |
|
|
|
2 | up to 1 MHz | No |
|
|
|
3 | up to 16 MHz | No |
|
|
|
4 | up to 20 MHz | No |
|
|
|
5 | up to 100 MHz | Yes |
|
|
|
6 | up to 250 MHz | Yes |
|
|
|
7 | up to 600 MHz | Yes |
|
|
|
The channel as a
Class | Specification | Approved |
|
|
|
A | up to 0.1 MHz | No |
|
|
|
B | up to 1 MHz | No |
|
|
|
C | up to 16 MHz | No |
|
|
|
D | up to 100 MHz | Yes |
|
|
|
E | up to 250 MHz | Yes |
|
|
|
F | up to 600 MHz | Yes |
|
|
|
| The higher the letter, the greater the demand on the transmission channel. For |
| Ethernet communication at 100 MHz, Category 5 (or higher) cables and at least |
| Class D capacity are required. |
|
|
|
|
|
|
RJ45 Connector | For direct Ethernet plug connections without interface elements, you can use |
| connectors such as IP 20 Data Plug (Harting(R)). You can assemble the cable |
| quickly by crimping the conductors; special tools are not required. |
|
|
|
|
|
|
Switches | To span distances of more than 100 m (328.1 ft) using SafeEthernet protocol, rail |
| switches of the RS2 series (Hirschmann(R)) with optical fibre ports are |
| recommended. |
