Functions

Controller Functions

Safety and standard execution

1756-L84ES provides 31 standard tasks and one safety task, with 1000 programs per task. The safety task supports Ladder Diagram; standard tasks support LD, ST, FBD and SFC.

Network capacity

The embedded 1 Gb EtherNet/IP port supports up to 250 EtherNet/IP devices and 15,000 OPC UA nodes with compatible firmware.

I/O and messaging

The controller supports up to 128,000 total I/O points. Front-port and backplane message rates depend on CIP Security mode and use of a safety partner.

Nonvolatile storage

A 4 GB 1784-SD4 Secure Digital card is preinstalled for project storage, backup and recovery workflows.

Interfaces

Communication Interfaces

EtherNet/IP

One embedded 10/100/1000 Mbps Ethernet port supports controller communication, integrated motion and EtherNet/IP networking.

USB service port

The USB 2.0 full-speed port operates at 12 Mbps and is intended for temporary local programming, configuration and firmware updates.

Status display

A four-character alphanumeric display provides controller status and diagnostic information for commissioning and maintenance.

Chassis communication

The one-slot controller communicates through the ControlLogix chassis backplane and may be installed in any compatible chassis slot.

Installation

Installation and Selection

Chassis placement

Install the one-slot controller in any compatible Series B or Series C ControlLogix chassis slot and follow official wiring and grounding instructions.

Safety architecture

For applications requiring SIL 3/PLe, confirm use and placement of the specified 1756-L8SP safety partner and validate the complete safety design.

Electrical loading

Allow for 5.0 mA at 1.2 V DC and 1.20 A at 5.1 V DC, with 6.2 W power dissipation and 21.2 BTU/hr thermal dissipation.

Mechanical reference

Use the Rockwell Automation official 2D drawing for 1756-L84ES when confirming dimensions, chassis spacing and enclosure clearances.

Safety Features

Safety integrity

The primary controller supports up to SIL 2/PLd. With the specified 1756-L8SP safety partner and approved architecture, the system can support up to SIL 3/PLe.

Safety memory

The exact 1756-L84ES catalog number provides 6 MB safety memory in addition to 20 MB standard memory.

Environmental limits

Operating temperature is 0 to 60 deg C in Series C chassis or 0 to 50 deg C in Series B chassis. The unit is open-style and not conformal coated.

Certification scope

Confirm required functional-safety certificates, firmware revisions and project standards against the current Rockwell Automation certificate set before commissioning.

FAQ

Frequently Asked Questions

Q1. How can I verify that a quotation is for the exact 1756-L84ES catalog number?

Match 1756-L84ES on the quotation, factory carton and controller nameplate. The correct model has 20 MB standard memory, 6 MB safety memory, 250 EtherNet/IP device capacity, embedded 1 Gb Ethernet and a four-character display.

Q2. How can I distinguish a new 1756-L84ES from used or refurbished equipment?

Request current photos of sealed packaging, catalog and serial labels, chassis connector condition, Ethernet and USB ports, display and the installed 1784-SD4 card. Opened seals, mounting marks or worn connectors can indicate prior use.

Q3. How should a buyer check whether a 1756-L84ES supplier is legitimate?

Verify the legal company name, business registration, bank beneficiary and traceable contact details. Require the supplier to cite the official 1756-L84ES cut sheet and publication 1756-TD001W-EN-P pages 44-47.

Q4. Which specifications should an engineer confirm before ordering 1756-L84ES?

Confirm 20 MB standard memory, 6 MB safety memory, 250 EtherNet/IP devices, firmware and Studio 5000 compatibility, chassis series, current draw, operating temperature and whether SIL 2 or a safety-partner-based SIL 3 architecture is required.

Q5. What physical evidence should be requested before payment for 1756-L84ES?

Request dated photos or video showing the exact nameplate, serial number, factory carton, status display, Ethernet and USB interfaces, backplane connector and preinstalled 4 GB SD card. Evidence must correspond to the quoted unit.

Q6. Can another GuardLogix 5580 suffix replace 1756-L84ES?

Not automatically. Suffixes can change standard and safety memory, node capacity, conformal coating, environmental rating and safety architecture. Models such as 1756-L84ESK or XT variants require a full engineering comparison and approval.
