STL Pro gramming 3 3-1 3. ST L Programm ing This chapter d iff ers fro m the rest of the contents in this manual as it has b een writ ten wi th a trainin g aspect in mind. STL/SFC pro g rammin g , althou g h havin g been available fo r man y y ears, is still misunderstood and misrepresented.
FX Series Programmable Controllers STL Pro gramming 3 3-2 3.2 How STL Ope rates As prev iousl y menti oned, S TL is a s y stem wh ich allows the user to write a pro g ram which functions in much the same wa y as a flow chart, this can be seen in the dia g ram opposite.
FX Series Programmable Controllers STL Pro gramming 3 3-3 Combined SFC Ladder representation Some times STL pro g rams will be w ritten in hard cop y as a co mbinat ion of both fl ow dia g ram and inte rnal sub-pro g ram. (example shown bel ow). Identif ication of cont act states 3.
FX Series Programmable Controllers STL Pro gramming 3 3-4 Initia l St eps For an STL pro g ram which is to be activated on the initial po wer up of the PLC, a tri gg er similar to tha t shown op posite co uld be used , i.e. us in g M8002 to drive the settin g of the initia l st a te .
FX Series Programmable Controllers STL Pro gramming 3 3-5 3.4 Moving Between STL Steps T o activate an ST L step the user must first drive the state coil. Settin g the coil has alread y been ide ntified as a wa y to s tart an ST L pro g ram, i. e. driv e an ini tial st ate.
FX Series Programmable Controllers STL Pro gramming 3 3-6 3.4.2 Using OUT to drive an STL coil This has the s ame operational feat ures as usin g SET . However , there is one ma j or functi on which SET is not used. This is to make what is termed ‘distant j umps’.
FX Series Programmable Controllers STL Pro gramming 3 3-7 3.5 Rules and T echniques For STL programs It can be seen that ther e are a l ot of advanta g es to usin g STL st y le pr o g ram min g but there are a few points a user must be aware of when writin g the STL sub-pro g ram s.

This can cause prob lems wit h dual coil s; particu larl y time rs.
FX Series Programmable Controllers STL Pro gramming 3 3-9 3.5.2 Single Signal Step Cont rol T ransferrin g between ac tive STL steps can be controlle d b y a si n g le si g nal. The re are two methods the user can pro g ram to ach i ev e this res u lt.

Een belangrijk punt na aankoop van elk apparaat Mitsubishi Electronics FX2NC (of zelfs voordat je het koopt) is om de handleiding te lezen. Dit moeten wij doen vanwege een paar simpele redenen:
Als u nog geen Mitsubishi Electronics FX2NC heb gekocht dan nu is een goed moment om kennis te maken met de basisgegevens van het product. Eerst kijk dan naar de eerste pagina\'s van de handleiding, die je hierboven vindt. Je moet daar de belangrijkste technische gegevens Mitsubishi Electronics FX2NC vinden. Op dit manier kan je controleren of het apparaat aan jouw behoeften voldoet. Op de volgende pagina's van de handleiding Mitsubishi Electronics FX2NC leer je over alle kenmerken van het product en krijg je informatie over de werking. De informatie die je over Mitsubishi Electronics FX2NC krijgt, zal je zeker helpen om een besluit over de aankoop te nemen.
In een situatie waarin je al een beziter van Mitsubishi Electronics FX2NC bent, maar toch heb je de instructies niet gelezen, moet je het doen voor de hierboven beschreven redenen. Je zult dan weten of je goed de alle beschikbare functies heb gebruikt, en of je fouten heb gemaakt die het leven van de Mitsubishi Electronics FX2NC kunnen verkorten.
Maar de belangrijkste taak van de handleiding is om de gebruiker bij het oplossen van problemen te helpen met Mitsubishi Electronics FX2NC . Bijna altijd, zal je daar het vinden Troubleshooting met de meest voorkomende storingen en defecten #MANUAl# samen met de instructies over hun opplosinge. Zelfs als je zelf niet kan om het probleem op te lossen, zal de instructie je de weg wijzen naar verdere andere procedure, bijv. door contact met de klantenservice of het dichtstbijzijnde servicecentrum.
