Function

Clock backup

The BB 1297 provides long-term buffering for the real-time clock of a compatible SIMATIC S7-1200 CPU.

Battery arrangement

A CR1025 cell is required for operation and must be sourced separately because it is not included.

Maintenance behavior

The host PLC uses its MAINT indication to show that battery replacement is required.

Installation

CPU receptacle

Fit the board in the signal-board receptacle of the S7-12XX CPU after isolating power and following ESD handling requirements.

Firmware prerequisite

Use only with a compatible CPU running firmware V3.0 or higher. Confirm the actual CPU firmware before purchase.

Mechanical envelope

Allow for the published 38 x 62 x 21 mm board size and avoid touching contacts during insertion.

Diagnostics

Maintenance indication

The Siemens data sheet confirms diagnostics and a maintenance LED indication through the PLC.

Replacement planning

Establish a controlled battery replacement procedure so that time settings and service records remain traceable.

Procurement evidence

Request a clear photo of the BB 1297 marking, connector area and sealed packaging, together with confirmation that the CR1025 cell is excluded.

Environment

Protection

The board is rated IP20 and must be installed inside a suitable control enclosure.

Temperature limits

The specified operating range is -20 to 60 C; storage and transportation range is -40 to 70 C.

Humidity and approvals

Maximum relative humidity is 95% at 25 C without condensation; Siemens lists CE, CSA, FM, RCM and marine approvals.

FAQ

Q1. How can the quoted battery board be verified as the exact model?

Check that the label reads 6ES7297-0AX30-0XA0 and BB 1297, then confirm the published 38 x 62 x 21 mm dimensions and approximately 40 g weight.

Q2. How can New, Used or Refurbished condition be distinguished?

Request close photos of the connector contacts, plastic housing, label and packaging. Insertion marks, scratched contacts or reworked labels may indicate prior use.

Q3. How should supplier legitimacy be checked?

Verify registration, address, bank beneficiary and Siemens automation supply history, and ask the supplier to reference the official BB 1297 product page in the quotation.

Q4. Which specifications must be checked before purchase?

Confirm the target S7-12XX CPU, firmware V3.0 or higher, signal-board receptacle availability, CR1025 battery requirement and IP20 enclosure conditions.

Q5. What evidence should be requested before payment?

Ask for dated photos of the exact board, full article number, contacts, packaging and quantity, plus written confirmation that the CR1025 battery is not included.

Q6. Can a similar battery board or suffix replace this model?

No substitution should be assumed. Mechanical fit, CPU firmware support, connector layout and article number must all match 6ES7297-0AX30-0XA0.
