Selection Guide
Use the checklist below to confirm this module is the correct choice for your application:
- ✅ Drive series is SIMOVERT MASTERDRIVES 6SE70xx
- ✅ Fieldbus protocol required is PROFIBUS-DP
- ✅ Drive has an available CB option slot
- ✅ PLC master supports PROFIBUS-DP (e.g., SIMATIC S7 with CP 342-5 or integrated DP port)
- ✅ Drive firmware is compatible with CB board revision
- ⚠️ If your drive is SINAMICS series → select 6SL3055-xxxx option boards instead
- ⚠️ If protocol is PROFINET → select the corresponding CBE (Communication Board Ethernet) variant

Replacement & Compatibility FAQ
Q: Can I use 6SE7090-0XX87-4AH0 on a SINAMICS G120 drive?
A: No. The 6SE7090-0XX87-4AH0 is designed exclusively for SIMOVERT MASTERDRIVES 6SE70 series. SINAMICS drives use a different option board architecture (e.g., 6SL3055 series).
Q: Is this module compatible with SIMATIC S7-1200?
A: The S7-1200 supports PROFIBUS-DP only via a CM 1243-5 communication module. If your S7-1200 has PROFIBUS-DP master capability, the 6SE7090-0XX87-4AH0 can be used as the drive-side slave.
Q: What is the difference between 6SE7090-0XX87-4AH0 and 6SE7090-0XX84-0KA0?
A: The suffix codes indicate different communication protocols and hardware revisions. The 4AH0 suffix typically denotes the PROFIBUS-DP variant. Always cross-check the suffix against the SIEMENS catalog or contact our team for clarification.
Q: Can I install this module myself?
A: Yes. The module slots into the drive’s option bay without tools. However, PROFIBUS-DP address configuration and parameter assignment (P918) must be performed via the drive keypad or STARTER software.
Q: Do you offer tested/refurbished units?
A: Yes. We offer both new OEM and tested-refurbished units. Please specify your preference when ordering.
