Frequently Asked Questions

Which controllers can a FLEX 5000 (5094) system connect to?

FLEX 5000 I/O is remote I/O for Logix 5000 controllers over EtherNet/IP — specifically ControlLogix 5580 (1756-L8 family), CompactLogix 5380 (5069-L3*ER family), and CompactLogix 5480 (5069-L4*ERMW family). The modules are configured in Studio 5000 Logix Designer. FLEX 5000 does not connect to older ControlLogix 5570 or CompactLogix 5370 controllers natively; use 1794 FLEX I/O for those platforms.

Do I need to order the terminal base and RTB separately?

Yes. Every FLEX 5000 I/O module requires a terminal base (TB) assembly consisting of a mounting base (5094-MB or 5094-MBXT for extended temp) plus a removable terminal block (RTB). Neither ships with the I/O module. Match the RTB to the module type: 5094-RTB3/RTB3S for most digital I/O, 5094-RTB3T/RTB3TS for RTD/TC or 32-channel wiring, 5094-RTB3W/RTB3WS for relay (OW8I), 5094-RTB3I/RTB3IS for isolated channels, 5094-RTB32V/32C for 32-point DC I/O (IB32, OB32), 5094-RTB3AC for AC modules (IA16, IM8, OA16). Add "S" for spring-cage, "XT" for extended temperature.

What's the difference between the 5094-AENTR and 5094-AEN2TR adapters?

Both are dual-port EtherNet/IP RJ45 adapters with DLR support. The AEN2TR is a higher-capacity second-generation adapter — 1880 mA MOD power vs 1250 mA on the AENTR, 1800 mA backplane vs 1130 mA, 6.2 W dissipation vs 5.1 W. Use AEN2TR for larger FLEX 5000 I/O systems drawing more backplane current. The AEN2TR also includes a USB port for local programming/configuration. SFP-variant adapters (AENSFPR, AEN2SFPR) accept 1783-SFP fiber transceivers in place of RJ45 ports for long-haul fiber runs.

What's the XT suffix on FLEX 5000 modules?

XT = Extended Temperature. XT-rated modules (e.g., 5094-IB16XT, 5094-OB32XT, 5094-AENTRXT) carry the same -40 to +70 °C operating range as standard catalogs but add ISA-S71.04 G3 corrosive-atmosphere compliance for harsh environments (vs ISA G2 on standard catalogs). XT modules are intended for marine, wastewater, mining, and similar applications with airborne corrosive contaminants. XT modules pair with 5094-MBXT mounting bases and -SXT-suffix RTBs.

Can FLEX 5000 modules be removed under power?

Yes. FLEX 5000 I/O modules support Removal and Insertion Under Power (RIUP). You may leave up to four consecutive empty slots in a FLEX 5000 system without disrupting backplane communication. Always verify area classification (Class I Div 2 / Zone 2) requirements before pulling modules in hazardous locations — RIUP is permitted by design but local code may require power-down.

What network topologies does FLEX 5000 EtherNet/IP support?

All 5094-AEN* adapters support Star, Linear, and Device-Level Ring (DLR) topologies on EtherNet/IP. DLR provides automatic media redundancy via beacon-based ring protocol — a single cable fault anywhere in the ring does not interrupt communication. For long fiber runs use the SFP variants (AENSFPR, AEN2SFPR) with 1783-SFP100FX/1GSX transceivers. CIP Sync (IEEE 1588) timestamping is supported across any topology.

Does FLEX 5000 support HART and IO-Link?

Yes — HART via the 5094-IF8IH (8-channel isolated HART input) and 5094-OF8IH (8-channel isolated HART output) modules, which provide HART handheld pass-through and secondary-variable access. IO-Link via the 5094-IJ2I (standard) and 5094-IJ2IS (safety) master modules. Both HART and IO-Link data are exposed to Studio 5000 tags, and HART process variables can be mapped to analog channel data blocks.
