Frequently Asked Questions

What is the difference between the ControlLogix 5570 and 5560 controllers?
The 5570 uses an Energy Storage Module (ESM) for memory backup at powerdown while the 5560 uses a battery. The 5570 has a built-in USB port; the 5560 has a built-in RS-232 serial port. The 5570 supports 500 controller connections versus 250 for the 5560. Nonvolatile memory is an SD card on the 5570 and a CompactFlash card on the 5560. The 5570 includes a scrolling status display plus four indicators; the 5560 has six status indicators only.
What catalog numbers are covered by this manual?
This manual covers 1756-L61, 1756-L62, 1756-L63, 1756-L63XT, 1756-L64, 1756-L65 (ControlLogix 5560 family) and 1756-L71, 1756-L72, 1756-L73, 1756-L73XT, 1756-L74, 1756-L75, 1756-L72EROM, and 1756-L73EROM (ControlLogix 5570 family).
What are the Armor ControlLogix controllers and how do they differ from standard 5570 controllers?
The Armor ControlLogix controllers (1756-L72EROM and 1756-L73EROM) combine a 1756-L72 or 1756-L73 controller with two EtherNet/IP DLR-capable 1756-EN3TR communication modules in an IP67-rated housing for machine mounting. Their functionality is identical to the 1756-L72 and 1756-L73, but their ESMs cannot be removed or replaced.
What are the extreme environment controller options and what temperature range do they support?
The extreme environment controllers are catalog numbers 1756-L73XT and 1756-L63XT. They provide the same functionality as the 1756-L73 and 1756-L63 respectively, but are designed to operate at temperatures from -25 to +70 °C (-13 to +158 °F).
How do I upgrade firmware on a ControlLogix 5570 or 5560 controller?
Firmware can be upgraded using ControlFLASH software packaged with the Studio 5000 environment, or by using the AutoFlash feature within the Logix Designer application. The controller must be in Remote Program or Program mode and all major recoverable faults must be cleared before accepting an upgrade. If the SD card is locked and the Load Image option is set to On Power Up, the firmware update will not apply; the previously stored firmware and project are loaded instead.
What ESM modules are compatible with 1756-L7x controllers?
Compatible ESM modules include 1756-ESMCAP, 1756-ESMNSE, 1756-ESMCAPXT, and 1756-ESMNSEXT. The 1756-L7x controllers ship with the 1756-ESMCAP installed. The 1756-ESMNSE can only be used with a 1756-L73 (8 MB) or smaller memory-sized controller. The 1756-ESMNRM and 1756-ESMNRMXT cannot be removed once installed.
What communication networks are supported in a ControlLogix system?
The ControlLogix system supports EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus (DH+), Universal Remote I/O, Foundation Fieldbus, and HART networks via communication modules installed in the chassis. The 1756-L6x controllers also include a built-in RS-232 serial port supporting DF1 Master, DF1 Point-to-Point, DF1 Radio Modem, DF1 Slave, DH-485, ASCII, and Modbus protocols.
