Table 10- 55 Implicit assignment of hardware to cyclic interfaces for p8839[0] = p8839[1] = 99
Plugged hardware interface
No option, only use Control Unit onboard interface
(PROFIBUS, PROFINET or USS)
CU320-2 DP with CBE20 (optional PROFINET
interface)
CU320-2 PN with CBE20 (optional PROFINET
interface)
CAN option CBC10
Parameter p8839[0,1] is used to set the parallel operation of the hardware interfaces and the
assignment to the cyclic interfaces IF1 and IF2 for the Control Unit drive object.
The object sequence for process data exchange via IF2 depends on the object sequence
from IF1; see "List of drive objects" (p0978).
The factory setting of p8839[0,1] =99 enables the implicit assignment (see table above).
An alarm is generated in case of invalid or inconsistent parameterization of the assignment.
Note
Parallel operation of PROFIBUS and PROFINET
The data of isochronous applications can only be processed via one of the two interfaces IF1
or IF2 (p8815). Two parameterization options are possible if additionally the PROFINET
module CBE20 is inserted in the CU320-2 DP:
- p8839[0] = 1 and p8839[1] = 2: PROFIBUS isochronous, PROFINET cyclic
- p8839[0] = 2 and p8839[1] = 1: PROFINET isochronous, PROFIBUS cyclic
Parameters for IF2
The following parameters are available in order to optimize the IF2 for a PROFIBUS or
PROFINET interface:
● Receive and send process data:
● Diagnostic parameters:
● Binector-connector converters:
● Connector-binector converters:
