Efficient Networks S120 manual Parameters, Additional parameters for IF2, P8839, Comm Board

Applications 11.1 Parallel operation of communication interfaces for CU320

Additional parameters for IF2

To permit a better use of the IF2 also for a PROFIBUS / PROFINET connection, the following extensions of the parameter list are available:

Infeeds:

r8850, p8851, r8853

Additional diagnostic parameters (meaning of 88xx identical with 20xx): r8874, r8875, r8876

Additional binector-connector converter (meaning of 88xx identical with 20xx): p8880, p8881, p8882, p8883, p8884, r8889

Additional connector-binector converter (meaning of 88xx identical with 20xx): r8894, r8895, p8898, p8899

Note

It is not possible in the HW Config configuration tool to represent a PROFIBUS / PROFINET slave with two interfaces. In parallel operation, the SINAMICS will therefore appear twice in the project or in two projects although there is only one physical device.

Parameters

p8839

Description:

Values:

PZD Interface hardware assignment

Assigns the cyclic interface a hardware interface.

Index 0: Assignment for interface 1 (IF1)

Index 1: Assignment for interface 2 (IF2)

0:not active

1:ONBOARD hardware

2:COMM BOARD

99:Automatic (assignment according to plugged HW, compatible setting)

The following rules apply to the setting of p8839:

●The setting of p8839 applies to all DOs of a CU (device parameter).

●For the setting p8839(0) = 99 and p8839(1) = 99 (automatic assignment, default), the assignment will be made on the basis of the plugged hardware. To render this automatic assignment active, it must be selected for both indexes; otherwise an alarm is generated, and the setting p8839(x) = 99 is treated in the same manner as 'not active'.

●An alarm is issued if the same hardware (onboard or COMM board) is selected in p8839(0) and p8839(1). In this case, the setting of p8839(0) is effective. The setting of p8839(1) is treated as 'not active'.

●With the CAN module plugged (CBC10), an entry of p8839(0) = 2 is invalid (no assignment of CAN module to IF1). An alarm is issued.
