8.3 Adapting a project (Upgrading the project / Replacing the SIMOTION controller)
8.3.5
Preparing the device replacement
Overview
The device replacement process differs from the platform replacement process in that it is
really easy to accept project data during device replacement.
The device replacement is performed via HW Config, whereas an XML export/import is
required for a platform replacement.
A device replacement is only possible within SIMOTION D.
The following devices can be interchanged:
● Replacement between different performance classes (e.g. D445‑2 DP/PN ⇔ D455‑2 DP/
PN)
● Replacement between generations (D4x5 ⇒ D4x5‑2)
● Replacement between variants (D425-2 DP ⇔ D425-2 DP/PN)
● Replacement between SIMOTION, SINAMICS and/or PROFINET version (e.g.
D425 V4.1 - PN V2.1 SINAMICS S120 V2.5 ⇒ D425 V4.2 - PN V2.2 SINAMICS S120
V2.6.2).
One SIMOTION D can only be replaced with another SIMOTION D if the SINAMICS version
involved is the same or higher. It is not possible to downgrade to a lower SINAMICS version.
Preparation
Before the device replacement can be performed, it is recommended that preliminary work be
performed in the existing project. The existing project must be adapted so that it can be mapped
to the new device during the device replacement.
Examples:
1. Number of DRIVE‑CLiQ interfaces
If the replacement is to a device with fewer DRIVE‑CLiQ interfaces, then the ports that are
no longer available must be rewired before the device replacement (double-click "Topology"
in the project navigator). Components on DRIVE‑CLiQ ports that are no longer available
are moved to the component archive during the device replacement.
Example:
Replacement of D445‑2 DP/PN (six DRIVE‑CLiQ ports) with D425-2 DP/PN
(four DRIVE‑CLiQ ports)
→ ports X104 and X105 are no longer available.
2. Number of CX32‑2s
If the replacement is with a D4x5‑2 that only supports a small number of CX32‑2 modules,
then a device replacement in HW Config is not possible.
In this case, the CX32‑2 must be replaced by a SINAMICS S120 CU320‑2.
3. PROFINET interface
If a D4x5 with CBE30 is replaced by a D4x5‑2 DP/PN with onboard PROFINET interface,
then the number of PROFINET ports is reduced from four to three.
Components on port 4 have to be rewired
