System features
Logix Designer application version v38.00 has these new and enhanced features.
New features

Support for ControlLogix 5590 controllers
This version of the Logix Designer application supports ControlLogix 5590 controllers. By default, ControlLogix 5590 controllers operate as Safety controllers. You can also configure them as Standard, Process, and Process Safety controllers.
Synchronize EPLAN projects with Logix Designer projects
Use the new Synchronize dialog to compare EPLAN AML project files with a project in the Logix Designer application. Use the Synchronize dialog to add project components to the open project or to the EPLAN AML project to keep them in synch. Synchronizing projects:
Saves repetitive editing--make updates in one project and synchronize them in others.
Minimizes human error when working across multiple systems.
Helps keep your device data consistent and up-to-date across your software tools. The Synchronize feature also expands the number of supported devices.

Generate Safety Signatures in Run mode
In this version of the Logix Designer application, you can generate a Safety Signature for ControlLogix 5590 and 5590XT, GuardLogix 5580, and Compact GuardLogix 5380 controllers when they are in Program and Remote Run modes.

Front-port crossloading redundancy on ControlLogix 5590 controllers

This version of the Logix Designer application adds front-port crossloading on a ControlLogix 5590 controller in a redundant project to improve the scan performance of tasks. When you enable front-port crossload, the controller blocks traffic on the front Ethernet ports and they cannot be used for browsing to other devices or links.
Enhanced features

New Timer_T data type

This version of the Logix Designer application includes the TIMER_T data type. The TIMER_T data type:

Further integrates the DateTime feature into the Logix Designer instruction set. You can set the Timer operand as TIMER or TIMER_T in the Timer On Delay (TON), Timer Off Delay (TOF), and Retentive Timer On (RTO) instructions. The TIMER_T data type has Accumulated (ACC) and Preset (PRE) members whose data type is TIME.
Clarifies elapsed time by displaying values in units of time: days (d), hours (h), minutes (m), seconds (s), milliseconds (ms), and microseconds (us). You no longer need to derive ACC or PRE values from a DINT that represents milliseconds.
FGEN instruction supported in safety applications
In this version of the Logix Designer application, you can use the Function Generator (FGEN) instruction in safety applications.
