More Information

Overview Manuals Redundancy Integration Handling Application
  • Two-slot ProcessLogix controller module
  • Supports nonredundant and redundant controller configurations
  • A qualified standby controller can assume control after primary failure

1757-PLX52 is an Allen-Bradley ProcessLogix controller module designed for ProcessLogix process-control platforms.

It executes control strategies and participates in the ProcessLogix server, controller, ControlNet, and I/O architecture, with redundant operation available when a matched second controller is configured.

Before installation or replacement, verify Series A hardware, chassis placement, controller firmware, network settings, battery backup, and the saved ProcessLogix strategy.

Availability, condition, price, and shipping time for 1757-PLX52 are confirmed during quotation.

  • The module can be used in nonredundant or redundant controller configurations
  • A second qualified controller can take over after a primary-controller failure
  • The redundant system depends on matched controller and system configuration
  • ControlNet provides the primary link among ProcessLogix servers, controllers, and I/O
  • Ethernet supports connections between ProcessLogix servers
  • The controller forms part of the integrated ProcessLogix server-to-I/O architecture
  • Removal and insertion under power are not supported
  • Document the installed controller role before replacement
  • Restore the approved ProcessLogix project and network configuration after installation
  • ProcessLogix continuous-process control systems
  • Redundant ProcessLogix controller configurations
  • ProcessLogix batch-control systems using RSBatch integration
Description
1757-PLX52 is an Allen-Bradley ProcessLogix controller module for ProcessLogix process-control systems.

The two-slot unit supports nonredundant use or redundant controller operation in which another configured controller can assume control after a primary-controller failure.

Before installation or replacement, confirm the complete catalog number, Series A hardware, compatible chassis, controller firmware, network architecture, battery arrangement, and saved ProcessLogix configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is 1757-PLX52 the correct controller for a redundant ProcessLogix system?
1757-PLX52 supports redundant controller configurations, but both controller positions, chassis hardware, firmware, networks, and the saved ProcessLogix strategy must be verified as one qualified system.
Can 1757-PLX52 be removed or inserted while the chassis is powered?
No. The official ProcessLogix catalog states that 1757-PLX52 does not support removal or insertion under power, so isolate power and follow the approved shutdown procedure.
Which battery arrangement should be checked when sourcing 1757-PLX52?
Confirm whether the installed controller uses the 1757-BEM battery extension module or the 1757-PLXBAT battery and match the existing backup arrangement before replacement.
What must be preserved before replacing 1757-PLX52?
Back up the controller strategy and document the chassis position, controller role, network settings, firmware, and redundancy configuration before removing the existing 1757-PLX52.
Does 1757-PLX52 include the redundancy module and fiber cable?
No. The controller module is separate from the 1757-SRM redundancy modules and the 1757-SRC-series fiber cables unless those items are explicitly listed with the supplied equipment.
How should a standby 1757-PLX52 be checked before service?
Verify that the standby controller is qualified with the primary, has the correct project and firmware, and can assume the intended control role without network or chassis faults.
Why might a replacement 1757-PLX52 fail to join the existing system?
Common documented risks include incompatible controller firmware, unmatched chassis configuration, incorrect network settings, missing project data, or an unqualified redundancy arrangement.
