4.14 Utilities

For the plannin

of the system bus accordin

to the drive tasks in question, there are

utilities in the form of tables.

The planning of the system bus is done in three steps:

1. Definition of the communication relationships

2. Production of the virtual links

3. Capacity check

The priority assignment of the identifiers is relevant for the definition of the communi-

cation relationships. Data that are to be transmitted with a higher priority must be

given low identifiers. This results in the message with the higher priority being trans-

mitted first with a simultaneous access of two nodes to the bus.

Note:

he recommended identifier ran

e for the communication relationships via

the PDO channels is 385 ... 1407.

The identifiers below 385 are used for the NMT telegrams (boot-up se-

quence, SYNC telegram) and emergency message.

The identifiers above 1407 are used for the SDO channel for parameteri-

zation.
