PROFIBUS DP interface for IS1+
2.10 CPU redundancy
Attention!
Two different solutions for CPU redundancy with PROFIBUS DP are available:
CPU redundancy according to PNO specification ´Slave Redundancy´
Doc. 2.212 R1.2 2004
CPM redundancy according to R.STAHL specification
is a proprietary solution from 2000.
IS1 supports both solutions. The two solutions are
not
compatible with one another and must be projected
differently. Therefore, a clear distinction must be made as to which version is to be used.
Selection for the 9442 CPU via the backplane switch S1:
S1 = 1
PROFIBUS PNO Redundancy.
(recommended for new projects)
S1 = 2
PROFIBUS Stahl Redundancy Addr. Offs. 1
S1 = 3
PROFIBUS Stahl Redundancy Addr. Offs. 0
The distinction between STAHL and PNO redundancy for the 9440 CPM is done by selecting the CPM
firmware and the associated GSE file:
*1) Attention!
When using GSE files from V3.03 in connection with IS1 9440 firmware up to V0x-41, a
parameterization error is reported when IS1 is started, if the PLC supports structured parameterization
according to DPV1 (e.g. S7-300 and S7-400). In this case, IS1 will not enter Data_Exchange.
Remedy: use firmware from V0x-42 or GSE up to 3.02.
A maximum of 15 IO-Modules
with IS1+ GSE
from V3.03
A mix of redundant CPMs with firmware acc. R.STAHL spec. and PNO spec. is not allowed in one IS1 field
station. Rule for redundant operation of two IS1 CPMs: Firmware from the same row (01-xx or 02-xx or 03-xx
or 09-xx) shall be used in both CPMs.
