At Automation Fair 2011, Rockwell Automation released the new 5730 line of CompactLogix controllers. These controllers allow users and machine builders to get the power of the Logix architecture for smaller applications. Here's an overview of the new line.

Rockwell Automation demonstrated a new line of lower cost , the 5730 line, at the 2011 Rockwell Automation Fair. The Rockwell Representatives who demonstrated these products at the Automation Fair booth noted that these controllers allow users to get the power of the Logix architecture for smaller applications. The CompactLogix 5370 CPUs are approximately two times faster than existing CompactLogix CPUs. The controllers are compatible with RSLogix5000 V20 and RSLinx Classic V2.58. (Note: This line is not usable with RSLogix5000 versions earlier than V20.) In presentations at Automation Fair, these controllers were recommended as a “SLC Migration option that provides Integrated Architecture benefits while mitigating risk.” There is SLC code translation available with RSLogix 5000 software to aide conversions.
Key 5370 highlights include:
The CompactLogix 5370 Controllers all have two EtherNet/IP ports with an option to support dual-port EtherNet/IP. The controllers can also be programmed to support Modbus/TCP (Rockwell has sample programming code available.)
USB 2.0 Port
All units have USB ports for flashing firmware, uploads, downloads, on-line edits, and bridging to the backplane. This is a device only port, not a host. It does not support ASCII communications or connection to visualization or other USB devices.
ASCII interface applications can be accomplished using 1769-ASCII, 1769-SM2, or 1734 ASCII I/O modules.
These units accept SD flash cards that eliminate batteries and provide program storage for auto load of program upon power up. The SD cards can also be used for application/project storage, firmware supervisor, runtime tag data read/write, fault dump during MNRF(Major Non Recoverable Faults). Each controller comes with 1GB SD Card.
CompactLogix 5370 L1, L2, and L3 Family
CompactLogix 5370 L1 Controllers
The smallest offering in the 5370 line are the L1 with 16 DC inputs and 16 DC outputs built-into the base controller. The starting price quoted at the show booth was $1,400 list price. The CompactLogix 5370 L1 series leverages the new high performance CPU in a small form factor and is the only Logix controller that uses Rockwell POINT I/O (commonly referred to as slice I/O) as a local IO system. The top model in the L1 controllers (1769-L18ERM-BB1B) supports 2 axis of motion control over EtherNet/IP with Kinematics function. This is the only CompactLogix controller that supports RIUP (Removal & Insertion Under Power) for local I/O. More Information.
5370 L1 Models
- L16ER-BB1B (16 DI, 16DO, dual EtherNet /IP DLR port, 384KB memory, 6 POINT I/O expansion modules, and up to 4 EtherNet/IP nodes)
- L18ER-BB1B (16DI, 16 DO, dual EtherNet /IP DLR port, 512KB memory, 8 POINT I/O expansion modules , and up to 8 Ethernet nodes)
- L18ERM-BB1B (16 DI, 16 DO, dual EtherNet /IP DLR port, 2 axis CIP motion, kinematics, 512KB memory , 8 POINT I/O expansion modules, and up to 8 Ethernet nodes)
Rockwell Automation defines these products on the ODVA website as providing a migration path for microcontroller users to move to RSlogix5000 from the Connected Components Workbench.
CompactLogix 5370 L2 Controllers
The 5370 L2 models all have 16 DC inputs and 16 DC outputs built-into the base controller. The largest controller (1769-L27ERM-QBFC1B) also has 4 universal analog inputs, 2 universal analog outputs, 4 high-speed counters and integrated motion on an EtherNet/IP network supporting s up to 4 axes. CompactLogix 5730 L2 controllers I/O may be expanded by adding up to 4 CompactLogix 1769 I/O modules. DeviceNet can be accommodated using an I/O module (1769-SDN or 3rd party module). The starting price quoted at the show booth was $2,500 list price.
5370 L2 Models
- 1769-L24ER-QB1B - 750 KB User Memory, 1 GB SD card (shipped with controller optional 2GB SD card), Embedded I/O, 8 EtherNet/IP and 120TCP Connections
- 1769-L24ER-QBFC1B - 750 KB User Memory, 1 GB SD card (shipped with controller optional 2GB SD card), 8 EtherNet/IP and 120TCP Connections, Additional Embedded I/O - 4 universal analog inputs, 2 universal analog outputs, 4 high-speed counters.
- 1769-L27ERM-QBFC1B - 1,000 KB User Memory, 1 GB SD card (shipped with controller optional 2GB SD card), 16 EtherNet/IP and 120TCP Connections, Additional Embedded I/O - 4 universal analog inputs, 2 universal analog outputs, 4 high-speed counters. This unit also supports up to 4 axes of integrated motion on an EtherNet/IP network.
CompactLogix 5370 L3 Controllers
The CompactLogix5370 L3 controller family has expanded scalability with more 1734 I/O modules, more axes support, more EtherNet/IP logical node connections. DeviceNet can be accommodated using an I/O module (1769-SDN or 3rd party module). The starting price quoted at the show booth was $4,500 list price.

Thoughts & Observations
This series of new controllers makes it more cost effective for users and machine builders to use the Logix architecture for smaller applications. During the 2011 Rockwell Automation Fair, I had a discussion about Rockwell’s product philosophy with Sujeet Chand, Senior Vice President and CTO at Rockwell Automation. Chand explained that any OEMs that are building machines that are going to be connected to other machines and require safety, integrated motion, and integrated drives, will need to use Logix products. He described how Rockwell Automation has created the 5370 L series of CompactLogix controllers to deliver lower cost controllers for “Logix Architecture OEMs,” who integrate safety, drives, motion, information, and configuration.
This may be the beginning of an entirely new ControlLogix family of controllers considering that, “The CompactLogix 5370 CPUs are approximately two times faster than existing CompactLogix CPUs.” Rockwell’s firmware revision control is another clue that this is a major system change. Rockwell Automation has locked down firmware for a number of existing controllers at Version 20 (V20) stating, “anomaly corrections will be deployed as appropriate.” There will be no future enhancements and V20 firmware remains available online for a number of controllers, including ControlLogix (1756-L61, L62, L63, L64, L65 1756-L61S, L62S, L63S), CompactLogix (1768-L43, L45 1768-L43S, L45S 1769-L35CR, L35E, L32E, L32C, L31), (1769-L23QBFC1B, L23EQB1B, L23EQBFC1B). V20 will continue in maintenance mode. The new 5370 controllers do not support V16 - V19 but do support V20 and V21. This version control is important since RSLogix software and controller firmware must be in step to use controllers in the Logix architecture.
