Communication

10.1 Communication according to PROFIdrive

The telegram structure

● The parameter p0978 contains the drive objects that use a cyclic PZD exchange. A zero

● If the value 255 is written to p0978, the drive unit emulates an empty drive object that is

● The following must apply to ensure conformity with the PROFIdrive profile:

● One PZD = one word.

● Only one of the interconnection parameters (p2051 or p2061) can have the value ≠ 0 for

● Physical word and double word values are inserted in the telegram as referenced

● p200x apply as reference variables (telegram contents = 4000 hex or 4000 0000 hex for

Structure of the telegrams

You can find the structure of the telegrams in the SINAMICS S120/S150 List Manual in the

following function diagrams:

● 2415: PROFIdrive - Standard telegrams and process data 1

● 2419: PROFIdrive - Manufacturer-specific telegrams and process data 1

● 2420: PROFIdrive - Manufacturer-specific telegrams and process data 2

● 2421: PROFIdrive - Manufacturer-specific telegrams and process data 3

● 2422: PROFIdrive - Manufacturer-specific telegrams and process data 4

Drive object

SERVO (EPOS)

SERVO (cl. loop pos ctrl)

is used to demarcate the drive objects that do not exchange PZD.

visible to the PROFIBUS master. This enables cyclic communication of a PROFIBUS

master in the following cases:

– with unchanged configuration to drive units that have a different number of drive

– with deactivated drive objects, without having to change the project

– Interconnect PZD receive word 1 as control word 1 (STW1).

– Interconnect PZD send word 1 as status word 1 (STW1). (Use WORD format for

double words if the input variable has the value p200x).
