The IC695PBS301-AA is a PACSystems RX3i PROFIBUS DP slave module. In normal operation it responds to requests from the PROFIBUS master and automatically exchanges the cyclic input and output data configured in the controller project; it does not control the bus as a master.

Install the module only in an IC695CHS012 or IC695CHS016 RX3i Universal Backplane. GE documentation requires an RX3i CPU with firmware 3.0 or later and Machine Edition Logic Developer PLC 5.0 SP3 or later for configuration.

Purchase verification

Confirm the complete -AA nameplate, Universal Backplane model, CPU firmware, station address, configured input/output areas, PROFIBUS master project, connector and termination before ordering.

Need a precise compatibility check?

Send Sales Manager Myrtle the complete IC695PBS301-AA nameplate, installed hardware details, required quantity and destination. We will review the stated configuration before quotation.

PROFIBUS master integration

Adds an RX3i controller as a configured DP slave beneath an existing PROFIBUS master.

Cyclic process data

Transfers the input and output byte areas defined in the RX3i and master projects.

DP-V1 access

Supports configured acyclic Read, Write and Alarm services alongside cyclic exchange.

Installed-system replacement

Restores a documented slave station after address, data map and termination checks.

What buyers should verify in the photos

Check that the full label reads IC695PBS301-AA. Review the 9-pin PROFIBUS connector, the three status LEDs, housing, latches and any revision details visible on the nameplate.

For an installed-system replacement, compare the photographed unit with the approved RX3i hardware configuration. Product-family appearance alone is not enough to confirm the correct revision.

Can IC695PBS301-AA replace an IC695PBS301-BA without changing the PROFIBUS application?

GE product information describes the -BA release as a label-only change with no change to function, performance or compatibility. Even so, compare the full nameplate, the approved hardware catalog and the saved controller/master projects before fitting a replacement.

Which rack and controller versions must I check before ordering IC695PBS301-AA?

Confirm an IC695CHS012 or IC695CHS016 Universal Backplane, an RX3i CPU with firmware 3.0 or later, and Machine Edition Logic Developer PLC 5.0 SP3 or later. The module is not specified for an RX3i expansion or remote backplane.

Do I need to set the PROFIBUS baud rate manually on IC695PBS301-AA?

No. The module automatically detects the network rate from 9.6 kbit/s through 12 Mbit/s. You still need a unique station address from 1 to 125, matching master configuration, correct cable polarity and termination.

Why is IC695PBS301-AA powered but not exchanging data with the master?

Read the two-word Slave Status area and check whether the module is waiting for parameters, waiting for configuration, in normal data exchange or reporting an error. Then verify the master is in RUN, the station address is unique, the configured byte counts match and the cable and terminations are intact.

How much process data can IC695PBS301-AA exchange, and can DP-V1 reduce the available cyclic data?

The module supports up to 244 bytes of cyclic input data and 244 bytes of cyclic output data. DP-V1 Read, Write and Alarm buffers use module capacity, so confirm the actual cyclic and acyclic allocation in the project rather than assuming the maximum is always available.

What information should I provide to confirm IC695PBS301-AA stock and compatibility?

Send the complete -AA nameplate, Universal Backplane model, RX3i CPU and firmware, Machine Edition version, station address, configured input/output areas and lengths, master/GSD configuration, LED or Slave Status information, connector and termination photos, quantity and destination.
