Frequently Asked Questions
How much fieldbus current can 6ES7157-0AC83-0XA0 supply?
The integrated PA supply supports up to 1000 mA for the connected segment.
Can 6ES7157-0AC83-0XA0 operate without diagnostic addressing?
Yes; address 0 provides transparent coupler operation without the diagnostic function.
How is diagnostic operation enabled on 6ES7157-0AC83-0XA0?
Assign a PROFIBUS address greater than zero and configure the corresponding diagnostic slave.
Can 6ES7157-0AC83-0XA0 be used in a redundant PA topology?
Yes; coupler or ring redundancy is supported with the specified redundant bus module and field distribution components.
How many PA devices can be planned behind 6ES7157-0AC83-0XA0?
Plan no more than 31 field devices and verify the segment current and voltage calculation.
What must be checked for the PA cable connected to 6ES7157-0AC83-0XA0?
Confirm segment length, cable type, terminators, load current and voltage at the most distant device.
What should be preserved before replacing 6ES7157-0AC83-0XA0?
Record the DP address, diagnostic mode, redundancy topology, PA load calculation and wiring assignments.
Compatibility & Ordering Notes
Compatibility Checklist
- Use the coupler with the specified DP/PA Link and compatible IEC 61158-2 PROFIBUS PA devices.
- For redundant operation, use the documented BM FDC/FDC redundant bus module and preserve the established topology.
- Calculate segment current, cable length and field voltage before commissioning.
