More Information

Overview Manuals Bus Assembly Installation Order Communication Check Pack Control

Features:

  • Supplies five replacement U-connectors in one package.
  • Joins adjacent modules mechanically and electrically.
  • Builds the modular backplane-bus path across an S7-1500 or ET 200MP station.
The 6ES7590-0AA00-0AA0 package contains five U-connectors, so the required quantity should be based on the number of adjoining S7-1500 I/O modules.

Seat each connector between the intended modules before the assembly is fixed to the rail; a displaced connector interrupts the self-assembling backplane bus.

After assembly, check that every module is fully latched and that the configured station order matches the physical backplane sequence.

The Siemens 6ES7590-0AA00-0AA0 S7-1500 U-Connector Five-Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Building the backplane path one module boundary at a time

  • First boundary: A U-connector links the first pair of adjacent station modules.
  • Bus continuation: Each following connector extends the electrical path to the next module.
  • Mechanical link: The connector also holds the mating geometry between the two housings.
  • Station chain: All installed boundaries together form the modular backplane bus.

Seating the connector before adjoining modules are locked

  • Power isolation: Deenergize the station before opening the module chain.
  • Connector placement: Fit the U-connector to the documented module side and orientation.
  • Module engagement: Slide and lock the adjoining module until the connector is fully seated.
  • Final inspection: Check every boundary before restoring power.

Relating one connector fault to downstream module loss

  • Local break: A loose connector interrupts the bus at its physical boundary.
  • Downstream effect: Modules after that point can disappear from the configured station.
  • Visual check: Inspect connector position and module locking before changing software.
  • Recovery: Restore full engagement, then confirm the configured hardware order online.

Managing five spare connectors without confusing them with modules

  • Quantity: One order number supplies five individual connectors.
  • No address: A U-connector has no separate process address or parameter set.
  • Storage: Keep unused pieces protected from bent contacts and contamination.
  • Issue record: Record which station boundary receives each replacement connector.
Description
Siemens 6ES7590-0AA00-0AA0 is a five-piece spare-parts pack of U-connectors for SIMATIC S7-1500 and ET 200MP stations. Each connector joins two adjacent modules and contributes one section of the modular backplane bus.

At each module boundary, 6ES7590-0AA00-0AA0 provides both the mechanical engagement and the electrical backplane path. The neighboring modules therefore communicate through a chain assembled from individual U-connectors rather than through a separate fixed rack backplane.

Installation of 6ES7590-0AA00-0AA0 begins by seating the connector on the module before the adjoining unit is locked onto the rail. Correct orientation and full engagement are required because a partially seated connector can interrupt communication to modules farther along the station.

The five connectors supplied under 6ES7590-0AA00-0AA0 are replacement components, not five independently addressed devices. Station power must be removed before a connector or module is fitted, and the final hardware order must still match the configured S7-1500 or ET 200MP layout.

Technical notes
Fit each Siemens 6ES7590-0AA00-0AA0 U-connector before mounting the adjoining module; never insert or remove modules while the station is energized.

How many connectors are supplied under Siemens 6ES7590-0AA00-0AA0?
Siemens 6ES7590-0AA00-0AA0 contains five individual S7-1500/ET 200MP U-connectors.
Does each 6ES7590-0AA00-0AA0 connector need a hardware address?
No. A 6ES7590-0AA00-0AA0 connector only joins adjacent modules and extends the backplane bus.
Why did downstream modules disappear after fitting Siemens 6ES7590-0AA00-0AA0?
Inspect the Siemens 6ES7590-0AA00-0AA0 connector at the first missing boundary for orientation, full seating and module locking.
Can 6ES7590-0AA00-0AA0 be installed while the S7-1500 is powered?
No. Deenergize the station before installing 6ES7590-0AA00-0AA0 or moving adjacent modules.
Is Siemens 6ES7590-0AA00-0AA0 a fixed backplane rack?
No. Siemens 6ES7590-0AA00-0AA0 is a pack of separate U-connectors used to assemble the modular backplane between adjacent modules.
What should be checked after replacing a connector from 6ES7590-0AA00-0AA0?
Confirm full engagement, correct module order and online visibility of every downstream module after using 6ES7590-0AA00-0AA0.
