Operating
Performance
No safety-relevant software faults are currently known; the known faults are assigned to
fault class 3 and lower.
Caution:
When working on initialization files (*.INI), tabs (09H) should not be used. Spaces (20H)
should be used instead. Failure to comply could lead to interpretation errors.
AS 488/TM with TELEPERM M I/Os:
The limitations with respect to use of TM I/Os (module types), all TM modules listed in the
"AS388/TM and AS488/TM supplementary system documentation" C79000-G8076-C700
or at catalogue PLT 112 and official notes in "TELEPERM M - aktuell" can be used.
Errors/failures/faults of the I/O buses are not displayed by LEDs on the TPM 478; these
can be recognized e.g. by failure signals of the drivers.
The module 6DS1607 operates with compatible functions, but the pulses which have been
accumulated in the previous cycle are always output when reading. The dead time is
reduced if a faster TPM 478 cycle is configured.
Operation of the coupling modules 6DS1318-8AB and 6DS1333-8AB as well as CP581-
TM, as far as compatible to S5Kx driver:
When using the firmware TPM 478, IO part, version 2 (Fixed memory package S79300-
G196-A900, 1. position = S79300-G196-A903-2, 2. position = S79300-G196-A904-2), only
telegrams with a maximum of 32 data words may be configured. Longer telegrams should
be split into two shorter ones. From module version 6 onwards, firmware version 3 is used,
which allows a maximum of 64 data words to be configured.
AS 488/TM with PROFIBUS-DP I/Os:
The process image length per slave station via PROFIBUS-DP is limited by the IF964-DP
to 122 bytes. It is thus possible to operate up to 7 analog modules with 8 channels each in
one slave station.
New modules can only be released for operation on the AS 488/TM by publishing them in
the PLT 112 Catalog, or as an addendum to TELEPERM M - aktuell.
When configuring ET200 I/O modules using COM ET200M, the value for the internal
monitoring time is calculated too low by the tool. The result may be that I/O modules are
not recognized (removed from COM PROFIBUS V3.0).
Remedy: Increase the value calculated by COM ET200M by a factor of 2.
