Programmable Logic P44x/EN PL/Hb6MiCOM 40 Agile P442, P444 (PL) 6-51 PROGRAMMABLE LOGIC (PSL)The Programmable Scheme Logic (PSL) is a module of programmable logic gates andtimers in the IED, which can be used to create customised internal logic. This is done bycombining the IED's digital inputs with internally generated digital signals using logic gatesand timers, then mapping the resultant signals to the IED's digital outputs and LEDs.The Programmable Scheme Logic (PSL) Editor allows you to create and edit scheme logicdiagrams to suit your own particular application.Further information is available in the Help system and in the Settings Application SoftwareGuide P40-M&CR-UG-EN-n, where n is the latest version of the settings applicationsoftware.1.1 Description of P442 and P444 Logic Nodes1.1.1 Sorted by DDB numberOrdinal English Text Description Source0 to 63 Relay Label 01 toRelay Label 64OUTPUT RELAY 1 toOUTPUT RELAY 64High level when a DDB cell (linked by PSL logic) is at 1.State depends on the logic set in the PSL (MiCOM S1Agile)These programmable relays are assigned in the defaultPSL, with the following logic conditions (see section1.8.2):- Pulse time-delay- Pick Up/Drop Off Time-delay- Dwell Time-delay- Pick Up Time-delay- Drop Off Time-delay- Latching- Straight (used in default PSL)RELAY64 Opto Label 01 OPTO ISOLATOR 1Set to 1 when the opto input is energised for a minimumtime: 7 ms (48 Vdc), 10 ms (universal) to be validated byinternal logicTo enable the selection of a setting group by statechange of the opto isolated logic inputs 1 and 2,disconnect Opto inputs 01 and 02 in the PSL (Optoinputs 01 and 02 must not be connected to any outputsignal)OPTO65 Opto Label 02 OPTO ISOLATOR 2Set to 1 when the opto input is energised for a minimumtime: 7 ms (48 Vdc), 10 ms (universal) to be validated byinternal logicTo enable the selection of a setting group by statechange of the opto isolated logic inputs 1 and 2,disconnect Opto inputs 01 and 02 in the PSL (Optoinputs 01 and 02 must not be connected to any outputsignal)OPTO66 to 95 Opto Label 03 toOpto Label 32OPTO ISOLATOR 3 toOPTO ISOLATOR 32Set to 1 when the opto input is energised for a minimumtime:7 ms (48 Vdc), 10 ms (universal) to be validated byinternal logicOPTO96 to173-- Unused174 General Alarm Groupment of all alarms PSL (OUT)175 Prot'n Disabled Protection is disabled and test mode enabled PSL (OUT)176 F out of Range Frequency tracking does not work correctly (provides aFrequency Out-of-Range indication)PSL (OUT)177 VT Fail Alarm Fuse failure indication (VT alarm).
