Features:
- Memory tier: 5 MB supports projects that exceed the entry 5580 allocation
- Integrated network: one 1 Gb EtherNet/IP interface serves the standalone controller path
- Data access: version 36 or later supports a published OPC UA node capacity
1756-L82E balances moderate application memory with a materially higher expansion path than the smallest standard 5580 controller.
1756-L82E can serve a standalone architecture or a qualified redundant design, but those two roles use different communication paths and motion boundaries.
1756-L82E procurement should connect the project revision, node inventory, redundancy intent, and SD-card recovery record to the exact supplied series and firmware.
Apter Power can review controller identity, official documents, redundancy scope, and quotation requirements for 1756-L82E.

- Version prerequisite: Logix Designer version 36 or later enables the published OPC UA capacity
- Model boundary: up to 600 OPC UA nodes defines the data-model ceiling for this catalog
- Engineering effect: namespace design and client demand should be validated with controller execution load
- Version 29: the I/O configuration supports as many as 80 EtherNet/IP nodes
- Version 30 onward: the published allowance increases to 175 EtherNet/IP nodes
- Counting rule: only devices added directly to the controller's I/O tree consume this node allowance
- Installed medium: a 4 GB 1784-SD4 card is supplied for nonvolatile storage
- Controlled image: firmware, project revision, and load mode should identify one approved restore set
- Service precaution: power and card removal must wait until SD activity has ended
- Scalable control: standard Logix projects needing more memory and network growth than the entry catalog
- Information integration: OPC UA data exposure on a supported version 36-or-later project
- High availability: qualified redundant control where separate communication modules provide external network paths
