FMS-PVXCL-S7
PROVOX™ 20-Series > S7-300™
Two solutions available :
Solution N°1 : FMS-PVXCL-S7-1
Removing I/O panels
Removing associated I/O cables
Removing I/O files CP6701
Replacing existing PCBs (Printed Circuit Board) of PROVOX™ I/O panels by PCBs of IOPs (Input Output Panels)
Solution N°2 : FMS-PVXCL-S7-2
Keeping existing I/O panels
Keeping associated I/O cables
Keeping I/O files CP6701 and removing communications and I/O cards
Installing PIAs (PROVOX™ Interface Adapters) in the existing CP6701 I/O files

3. PROVOX™ 20 series > S7-300™ Using IOPs
FMS-PVXCL-S7-1
PROVOX™ 20 series > S7-300™ Using IOPs
No existing PROVOX™ hardware is kept (I/O File – I/O card – I/O panel – I/O cable)
Existing PROVOX™ I/O panels are replaced by new IOPs which are electrically and mechanically fully compatible
Existing wiring is kept in place
Time for Hardware migration from an old toward a new I/O panel : about 30mn per panel
I/O card and I/O panel to be removed

6. Advantages FMS-PVXCL-S7-1 The main advantages of the IOPs panels
for PROVOX™ migration are as follow :
Existing wiring is just disconnected and reconnected
without any change at the same place
(same terminals with same labelling and same electrical features)
The existing loop drawings are kept without any modification,
allowing all maintenance processes and procedures
to remain unchanged.
