Properties of the cyclic interfaces IF1 and IF2

The following table shows the different features of the two cyclic interfaces:

Table 11-1 Properties of the cyclic interfaces IF1 and IF2

Feature	IF1		IF2
Setpoint (BICO signal source)	r2050, r2060		r8850, r8860
Actual value (BICO signal sink)	p2051, p2061		p8851, p8861
PROFIdrive conformance	Yes		No
PROFIdrive telegram selection (p922)	Yes		No
Isochronous mode possible	Yes		No
Slave-to-slave communication (PROFIBUS only)	Yes		Yes
List of drive objects (p978)	Yes		Yes
Max. PZD (16bit) setpoint / actual value SERVO	16 / 19		16 / 16
Max. PZD (16bit) setpoint / actual value vector	32 / 32		16 / 16
Max. PZD (16bit) setpoint / actual value infeeds	5 / 8		5 / 8
Max. PZD (16bit) setpoint / actual value TM41	16 / 19
Max. PZD (16bit) setpoint / actual value TM15	30 / 30
Max. PZD (16bit) setpoint / actual value TM17	36 / 36
Max. PZD (16bit) setpoint / actual value TM / TB (other)	5 / 5

Table 11-2 Implicit assignment of hardware to cyclic interfaces
Plugged hardware interface		IF1		IF2
No option, onboard interface only (PROFIBUS)		Onboard		--
PROFINET option (CBE20)		COMM board		--
CAN option (CBC10)		Onboard		COMM board
PROFIBUS option		Onboard		--

For parallel operation of the hardware interfaces and the explicit assignment to the cyclic interfaces IF1 and IF2, the new parameter p8839[0,1] "PZD Interface hardware assignment" exists for the device IO in the expert list.

The default setting of p8839[0,1]=99 enables the implicit assignment (see table above).

An alarm is generated in case of unvalid or inconsistent parameterization of the assignment.

Note

Parallel operation of PROFIBUS and PROFINET

Isochronous applications can only run via the cyclic interface IF1. With an additional

PROFINET module plugged in, there are two parameterization options:

-p8839(0) = 1 and p8839(1) = 2: PROFIBUS isochronous, PROFINET cyclic

-p8839(0) = 2 and p8839(1) = 1: PROFINET isochronous, PROFIBUS cyclic
