PROFIBUS DP interface for IS1+
Hint compatible mode:
Module descriptors with
´No Stat´, ´9470/2´
or
´9471/1´
in the Profibus GSE description use the data format
of the IS1 modules without separate signal status bits. The new IS1+ IO-Module operate in a compatible
mode and emulate one of the older IS1 IO-Module in this case.
Signal Status via status code in the AI data word is available always.
Advantage:
Support and easier engineering of AS systems, which do not support separate signal status.
Disadvantage:
When using IS1 DTM or I.S.Wizard is to note in this case, that the compatible older
IS1 IO-Module without signal status bits has to be configured in these tools manually to enable a consistent
upload of the parameter from IS1. The ´scan topology´ function of FDT frames or the function ´Generate
Configuration Data According Hardware´of I.S.Wizard cannot be used in this case because here the
descriptors of the IS1 + IO-Modules and not the descriptors of the older IS1 IO-Modules are added to the
project. Mapping of compatible IO-Module see
Compatibility of new IS1+ IO-Module
Therefore the use of module descriptions with
´No Stat´, ´9470/2´
or
´9471/1´
in combination with
applications using IS1 DTM or I.S.Wizard is possible with above mentioned reservations, but not
recommended.
The telegram length of the cyclic input and output data of a field station depends on the type and number of
IO-Module used. The above mentioned limits of a field station depending on the used CPU and GSE version
must also be observed here.
Moreover, further limitations of the number of IO-Modules, the maximum number of signals and the maximum
number of slaves in a network ... depend on the performance of the DP master used. Thus, the limits of the
DP master used must also be taken into account during the engineering.
Compatibility of new 9442 CPU
9442 CPU with power module PM 9444 and socket 9496 can replace previous 9440/15 CPM fully compatible
with the exception of line redundancy.
Existing configurations of 9440/15 with GSE V2.xx or GSE V3.XX can remain in the PROFIBUS Master
unchanged. The limitations of data length on PROFIBUS of the CPM 9440/15 remain unchanged in this
case.
If extended data length of 9442 CPU shall be used, a modified configuration with 9442 CPU and GSE V4.xx
(DPV0) or V5.xx (DPV1) has to be configured.
