More Information

Overview Manuals Networking Expansion Firmware Application
  • SLC 5/05 processor for an installed SLC 500 control architecture
  • Ethernet and RS-232 channels support the documented controller communications
  • Program, network, and chassis records must be preserved before migration

1747-L552 provides the processor function for an SLC 500 system and coordinates the installed local and remote I/O.

Communication capability depends on the hardware Series, configured firmware, Ethernet requirements, and Channel 0 protocol used by the application.

Before replacement, archive the project and document the chassis, slot assignments, specialty modules, network nodes, serial devices, and acceptance requirements.

Availability, condition, price, and shipping time for 1747-L552 are confirmed during quotation.

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.
Does Allen-Bradley 1747-L552 support 100 Mbps Ethernet?
Series C hardware introduced 10/100 Mbps Ethernet and supports up to 48 connections; earlier Series A and B units use 10 Mbps half-duplex Ethernet.
What should be backed up before replacing Allen-Bradley 1747-L552?
Back up the controller program, data files, channel settings, IP configuration, messaging paths, and the firmware/Series record before removing the processor.
Can Allen-Bradley 1747-L552 communicate through Channel 0?
Yes. The RS-232 channel supports documented DF1, ASCII, and DH-485 configurations; the configured protocol must be preserved during replacement.
How should chassis expansion be checked for Allen-Bradley 1747-L552?
Verify the installed SLC 500 chassis arrangement, expansion cables, slot addresses, power-supply loading, and the documented limit of three chassis and 30 slots.
Why does the hardware Series matter when replacing Allen-Bradley 1747-L552?
Ethernet capability and firmware compatibility vary by Series, so the nameplate Series, firmware revision, communication requirements, and project file must be matched.
What migration information is needed for Allen-Bradley 1747-L552?
Record local and remote I/O, specialty modules, messaging, HMI/SCADA links, Ethernet nodes, serial devices, and the machine acceptance requirements before choosing a replacement architecture.
Which official documents should be reviewed for Allen-Bradley 1747-L552 replacement?
Use the Rockwell Automation product lifecycle page, SLC 500 selection information, SLC 5/05 installation instructions, and the documentation for the installed modules and network.
