Features:
- Safety capacity: 5 MB standard memory and 2.5 MB safety memory remain separate allocations
- Network scale: the model supports as many as 175 EtherNet/IP nodes
- Data integration: version 36 or later supports a 900-node OPC UA model
1756-L82ES targets GuardLogix systems that need more standard logic, safety content, and network scope than the compact safety catalog.
1756-L82ES combines control and information functions, but the safety task, signatures, memory, and validation state remain independently governed.
1756-L82ES selection should connect the integrity target, partner decision, redundancy intent, software baseline, and commissioning evidence before hardware is ordered.
Apter Power can support model verification, safety-architecture review, official documents, and quotation coordination for 1756-L82ES.

- Software prerequisite: Logix Designer version 36 or later enables the published OPC UA function
- Model allowance: up to 900 OPC UA nodes supports a substantial diagnostic information model
- Deployment boundary: client access must not replace the validated safety function or its required tests
- Standard pool: 5 MB serves the standard Logix application
- Safety pool: 2.5 MB is reserved for governed safety content
- Change control: compiled usage and margin must be reviewed independently for both allocations
- Primary path: the controller supports safety applications through SIL 2 and Category 3/PLd
- Partner path: a qualified 1756-L8SP is required for SIL 3 and Category 4/PLe
- Validation effect: the partner, signatures, I/O paths, and fault reactions form one approval scope
- Larger safety projects: integrated standard and safety control using separately governed memory
- Networked machinery: GuardLogix architectures with a higher EtherNet/IP device population
- Diagnostic integration: qualified OPC UA exposure of controller data without replacing safety validation
