Frequently Asked Questions
What are the main differences between ControlLogix 5590, 5580, and 5570?
5590 is the newest (2025) top-tier family with dual embedded Ethernet, USB-C, up to 80 MB standard memory, and IEC 62443-4-2 SL1 security. 5580 is the mid- generation platform with a single Ethernet port, up to 40 MB memory, and USB 2.0 Type-B. 5570 is the prior generation with up to 32 MB memory and a serial RS-232 port on several variants. All three use the same ControlLogix backplane and 1756-A chassis family.
Which 1756 chassis work with these controllers, and which sizes are available?
The standard chassis family is 1756-A4 (4-slot), A7 (7-slot), A10 (10-slot), A13 (13-slot), and A17 (17-slot), in Series B and Series C. K-suffix (A7K, A10K) are conformal coated. XT variants (A7XT, A10XT, A7ZXT, A10ZXT) support the -25…+70 °C XT temperature range. All 5580 and 5590 controllers are single-slot and can go in any slot of the chassis.
How do I achieve redundancy on ControlLogix, and what are my options?
Three paths. (1) Traditional redundancy uses a pair of ControlLogix chassis each with a 1756-RM3 or RM3-2SFP module (legacy RM2 also supported) and identical controllers — works on 5580 and 5570. (2) On 5590, a primary controller plus a 1756-L9SP safety partner in the adjacent slot achieves SIL 3/PLe without a redundant chassis. (3) Logix SIS (Studio 5000 v38 and later) allows a redundant 5590 pair to achieve SIL 3/PLe with no safety partner — see user manual 1756-UM901.
What is the 1756-L9SP safety partner and do I need one?
The 1756-L9SP is a second processor module that sits in the chassis slot immediately to the right of a ControlLogix 5590 primary controller. With the partner installed, the system is capable of SIL 3 / PLe (Cat. 4). Without it, a 5590 standalone can still reach SIL 2 / PLd (Cat. 3) using the controller's safety task and safety I/O. As of Studio 5000 v38 and Logix SIS, a redundant 5590 pair no longer needs the L9SP to hit SIL 3.
Which modules are required for EtherNet/IP vs. other networks?
Built-in Ethernet: 5590 has two embedded ports, 5580 has one — sufficient for most applications. Add 1756-EN4TR, EN2T, EN2TR, or ENBT modules for additional EtherNet/IP segments or DLR rings. ControlNet requires 1756-CN2A, CN2B, CNB/D, or CNB/E. DeviceNet requires 1756-DNB. Legacy Data Highway Plus and Remote I/O are supported on 5580 via dedicated bridges. SERCOS motion uses a SERCOS interface module plus analog options (encoder, LDT, SSI).
What memory card ships with these controllers and can I replace it?
ControlLogix 5580 ships with a pre-installed 4 GB Secure Digital card (1784-SD4 standard, 1784-SD4XT on XT variants). ControlLogix 5590 ships with an 8 GB microSD card (1784-MSD8 standard, 1784-MSD8XT on XT variants). Both are removable and swappable through Studio 5000; they hold the user program, tags, and optionally the firmware for load-on-powerup. Larger versions may be available — see the Memory Cards accessory section of the publication.
