More Information

Overview Manuals Network Roles LIST Configuration Migration Control Application
  • System Coordination: Organizes several PLC-3 communication duties within one installed module
  • Migration Reference: Uses the retained LIST record as the basis for rebuilding channel assignments
  • Return-to-Service Focus: Validate each configured communication path before production resumes

1775-S5 coordinates multiple communication assignments within a PLC-3 installation rather than operating as a single-purpose network port.

The installed LIST record is the essential migration reference because it defines the operating duty and rack relationship of every channel.

During return to service, apply the retained plan, reconfigure the channels in sequence, and verify the connected I/O and peer paths before enabling production.

Availability, condition, price, and shipping time for 1775-S5 are confirmed during quotation.

  • Four channels support I/O adapters, node adapters, backup scanners, and compatible peer processors.
  • Channel 4 can also be configured for Data Highway or Data Highway Plus communication.
  • A programming terminal can access the documented PLC-3 configuration functions.
  • Use LIST to assign channel functions, rack ranges, and channel-specific parameters.
  • Requested changes are not active until the affected channel is reconfigured.
  • A scanner with thumbwheel address 1 is required in the chassis containing the front panel.
  • Exclude module status area E2 from the logical save used for an S4-to-S5 migration.
  • Clear memory after changing scanner families, then restore the verified application.
  • Recreate and validate every S5 communication channel in LIST before production.
  • PLC-3 remote I/O scanning across compatible I/O chassis and adapters.
  • PLC-3 communication over Data Highway or Data Highway Plus on channel 4.
  • PLC-3 backup, peer-to-peer, or programming-terminal communication.
Description
Allen-Bradley 1775-S5 is a PLC-3 scanner and communication adapter for I/O, Data Highway, Data Highway Plus, backup, peer, and programming links.

Its four channels can communicate with I/O adapters, node adapters, compatible backup scanners, PLC-5 products in adapter mode, and other PLC-3 processors; channel 4 also supports DH or DH+.

Migrating from an S4A or S4B requires the documented logical-save, memory-clear, restore, and LIST reconfiguration procedure rather than a simple physical card exchange.

Technical notes
1775-S5 commissioning requires a verified logical save, cleared and restored memory, matching thumbwheel, channel termination, rack range, network roles, and LIST configuration; an S4-to-S5 swap is not plug-and-play.

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.
What must be saved before replacing Allen-Bradley 1775-S5?
Make a verified logical save of the controller memory and record every scanner channel, rack range, station address, thumbwheel setting, termination choice, and backup connection.
Can Allen-Bradley 1775-S5 directly replace 1775-S4A or 1775-S4B?
Only with the documented migration: save memory without module status area E2, clear memory, install the scanner, restore memory, and configure each S5 channel in LIST.
How should a buyer check the network duties assigned to Allen-Bradley 1775-S5?
Identify whether each channel serves I/O, backup, peer communication, programming, DH, or DH+, and record channel 4 separately because it supports the additional DH/DH+ roles.
Why is the terminal-arm termination arrangement important for Allen-Bradley 1775-S5?
Removing the terminal swing arm also removes an enabled internal terminator, so an end-of-link scanner can leave the network unterminated unless the original scheme is preserved.
What should be verified in a redundant system using Allen-Bradley 1775-S5?
Confirm matching scanner types in primary and backup processors, the backup cable, channel settings, station-number behavior, and the documented switchover procedure.
What can prevent Allen-Bradley 1775-S5 auto-configuration from finding an I/O chassis?
The controller must be in program-load mode, chassis power must be present, restart lockout must allow restart, and a valid communication path to the adapter must exist.
Why can Allen-Bradley 1775-S5 power up yet leave PLC-3 communications inactive?
Restoring memory without recreating the LIST channel configuration can leave I/O, DH/DH+, backup, or peer links inactive even when the scanner powers up normally.
