• Configurable logic blocks that do not propagate the time stamp and the quality of signals.They do not have the suffix QT at the end of their function block name, for example,SRMEMORY. These logic blocks are also available as part of an extension logic packagewith the same number of instances.• Configurable logic blocks that propagate the time stamp and the quality of signals. Theyhave the suffix QT at the end of their function block name, for example, SRMEMORYQT.12.6.1 Application GUID-F5D6F065-441B-4296-AC56-F4DC1F5487E3 v3A set of standard logic blocks, like AND, OR etc, and timers are available for adapting the IEDconfiguration to the specific application needs. Additional logic blocks that, beside the normallogical function, have the capability to propagate timestamp and quality are also available.Those blocks have a designation including the letters QT, like ANDQT, ORQT etc.12.6.2 Setting guidelines GUID-E6BD982D-9E47-4CC2-9666-6E5CABA414C0 v3There are no settings for AND gates, OR gates, inverters or XOR gates as well as, for ANDQTgates, ORQT gates or XORQT gates.For normal On/Off delay and pulse timers the time delays and pulse lengths are set from thelocal HMI or via the PST tool.Both timers in the same logic block (the one delayed on pick-up and the one delayed on drop-out) always have a common setting value.For controllable gates, settable timers and SR flip-flops with memory, the setting parametersare accessible via the local HMI or via the PST tool.12.6.2.1 Configuration GUID-D93E383C-1655-46A3-A540-657141F77CF0 v4Logic is configured using the ACT configuration tool in PCM600.Execution of functions as defined by the configurable logic blocks runs according to a fixedsequence with different cycle times.For each cycle time, the function block is given an serial execution number. This is shown whenusing the ACT configuration tool with the designation of the function block and the cycle time,see example below.IEC09000695_2_en.vsdIEC09000695 V2 EN-USFigure 82: Example designation, serial execution number and cycle time for logicfunction1MRK 504 158-UEN A Section 12Logic187Application manual
