Process or field communication<br />
Typical practice-related data<br />
1<br />
A list of the field devices which can be interfaced to<br />
the relevant networks <strong>for</strong> the purpose of process or<br />
field communication.<br />
2<br />
Configuring <strong>and</strong> commissioning can be done anywhere<br />
on the network.<br />
The freely selectable communication relationships are<br />
thus extremely flexible, easy to convert, <strong>and</strong> easy to<br />
change.<br />

Slaves are network nodes on the PROFIBUS which<br />
send data back to the master at the master's request.<br />

AS-i is a single-master system with cyclic polling.<br />
The AS-i cycle time is the time it takes <strong>for</strong> the master<br />
The bus cycle time is understood to mean the time it<br />
takes <strong>for</strong> each master (active bus nodes) to receive<br />
When using electrical components, local networks<br />
can extend over the distance defined in the st<strong>and</strong>ards.<br />
The method of cabling used between the stations is<br />
referred to as the network topology.<br />
to poll the slaves, which is done at precisely<br />
predetermined intervals.<br />
the token (the right to send) precisely once.<br />
Greater distances can be bridged using optical<br />
components.<br />

Transmission media are either two-wire cables or fiber-<br />
The degree of protection is shown as IPxy, whereby<br />
the first digit (x) refers to shock-hazard protection as<br />
well as protection against solid bodies.<br />
St<strong>and</strong>ards are international norms or guidelines<br />
In some networks, the power supply <strong>for</strong> the bus nodes<br />
The term 'interface' or 'interfacing' is understood to<br />
mean the physical method of connecting bus nodes<br />
to the bus cable.<br />
optic cables.<br />
The second digit (y) indicates protection against water.<br />
The higher the digit, the greater the protection.<br />
stipulating product properties <strong>and</strong> characteristics.<br />
is also supplied by means of the bus.<br />
