Automation CompactLogix 1769 vs. 5069 Series
Sep 24, 2022
Automation CompactLogix™ 1769-L3x controllers are discontinued and no longer available for sale. To support your transition, we recommend that you migrate to our CompactLogix™ 5380 control platform. Similar to the CompactLogix™ 1769-L3x controllers, the CompactLogix™ 5380 controllers offer serial communications, better performance, increased security and more memory. 1769 Controllers The 1769 family of controllers started with the L1x, L2x and L3x, then continued with the 5370 series controllers. These controllers are part of the Logix line of Process Automation Controllers (PAC) from and are designed to accommodate small to medium sized automation projects. Some common features of the 1769 series are dual RJ45 ports for Ethernet/IP (only a single IP address allowed), LED status indicators on the front of the processor, a USB and SD card port for programming and storage, and a program/run/remote mode switch. Options in the series allow for up to 48 Ethernet/IP nodes, 16 axes of motion, and integrated safety functions. 1769 family IO modules can either be locally or remotely located, and other families of IO can be remotely connected to the controllers. Until the introduction of the 5069 CompactLogix family these controllers were the premier solution for smaller projects and will continue to be supported and have a place in the automation environment. 5069 Controller The 5069 family is a definite upgrade from the 1769 family of CompactLogix controllers. Two versions of this controller exist, the 5380 and the 5480 series of controllers. The 5380 controllers also sport dual RJ45 ports for Ethernet/IP (plus the ability to have dual IP addresses), a program/run/remote switch, LED status indicators, and a USB and SD card port. The similarities between the 1769 and 5069 families end there, though. The 5380 controllers have an integrated power supply and associated wiring connections, a four-digit digital status display, and integrated wiring terminals for processor and field power. Options in the family allow for up to 55 Ethernet/IP nodes, 20 axes of motion, and integrated safety functions. Comparison The differences between the two families become evident when you start looking at the performance of each. The 5380 controllers utilize new technology, allowing for improved scan times, communications, and capabilities. One of the biggest differences that programmers will notice is the change in memory reserve. In 1769 controllers, at least 20% of the available memory is needed to be reserved for communications and housekeeping operations while in the 5069 controllers all the available memory is usable for programming (the communications and housekeeping functions have been allocated to other memory.) The biggest advantage of this is that most programs can be moved from a 1769 controller to a smaller (and less expensive) 5069 controller. Additionally, the 5380 allows for dual Ethernet addresses instead of a single Ethernet address, allowing for...
