In addition, it means that the bus cycle time can be shortened when higher-performance components are being used. This makes calculation of bus parameters more exact. When using optical components for PROFIBUS DP: when configuring with an optical ring, you can specify the optical link modules (OLMs) to be used.In a manner similar to that for PROFIBUS DP slaves, you can now set the watchdog time for PROFINET IO devices: as an object property of the IO device in the "IO Cycle" tab.If the IP addresses are already assigned, you can specify the action to be taken upon insertion (retain addresses or assign new ones). There is improved handling when inserting copied IO devices into another station.This means that short and equal-length bus-cycle times can also be configured for PROFINET IO (see Introduction: Isochronous Realtime Ethernet). PROFINET IO with IRT Communication (Isochronous Realtime) is supported.Ěs of STEP 7 V5.4, you can have module times displayed in the local time of your programming device (PG)/PC.You can configure a watchdog time for PROFINET IO devices (see Configuring the Watchdog Time).
Ěpplications for editing objects in HW Config can now be started with the Edit > Open Object menu command (see Opening Objects in HW Config).The "Software Redundancy" function now allows PA links with subordinate PA slaves to be copied and redundantly inserted (see Configuring SW Redundancy).Each of the redundantly used interface modules can now send the updated firmware through the active backplane bus to the other, redundant interface module. The firmware for PROFIBUS DP interface modules can also be updated during redundant mode, as long as such a module will support this process.In this way, data can be exchanged between STEP 7 and CAD systems or CAE engineering systems (see Exporting and Importing CAx Data) The interface module must support this function. Identification data can also be written to PROFIBUS DP interface modules during redundant mode (by means of "Accessible Nodes").This function is also available in the SIMATIC Manager (see Identification and Maintenance (I&M)). The "Information and Maintenance" process is supported in order to be able to read identification data from or write identification data to modules.
In order to do this, you must have installed SIMATIC Logon V1.3 SP1 (as of now referred to as SIMATIC Logon) (see What You Should Know About Access Protection).

You can select a display in the respective STEP 7 national language and or in ISO 8601 standard format. Ěs of STEP 7 V5.4, there are two formats available for displaying the date and the time.Same bugs as always (f***'in FBD/LAD editor).
