    Introduction 1 Introduction Overview 1) Scope of this manual This manual gives details on all aspects of operation and programming for FX, FX , FX , FX and FX programmable controllers (PLCs). For all information relating to the PLC hardware and installation, refer to the appropriate manual supplied with the unit. 2) How to use this manual This manual covers all the functions of the highest specification Programmable (Logic) Controller (PLC).

  • Page 20: What Is A Programmable Controller

    Introduction 1 What is a Programmable Controller? A Programmable Logic Controller (PLC or programmable controller) is a device that a user can program to perform a series or sequence of events. These events are triggered by stimuli (usually called inputs) received at the PLC or through delayed actions such as time delays or counted occur-rences.

    Introduction 1 CPU version numbers Over time Mitsubishi adds newer and better features to develop and enhance the products. Because of the nature of PLCs, that can be likened to ‘industrial computers’, changes sometimes occur within the units main CPU (Central Processing Unit). These changes are similar to those experienced by office and home computer users, that is, going to a version up processor.

  • Page 27: What Is A Program

    FX Series Programmable Controllers Basic Program Instructions 2 Basic Program Instructions What is a Program? A program is a connected series of instructions written in a language that the PLC can understand. There are three forms of program format; instruction, ladder and SFC/STL. Not all programming tools can work in all programming forms.

  • Page 28: How To Read Ladder Logic

    FX Series Programmable Controllers Basic Program Instructions 2 How to Read Ladder Logic Ladder logic is very closely associated to basic relay logic. There are both contacts and coils that can be loaded and driven in different configurations. However, the basic principle remains the same.

    FX Series Programmable Controllers STL Programming 3 STL Programming This chapter differs from the rest of the contents in this manual as it has been written with a training aspect in mind. STL/SFC programming, although having been available for many years, is still misunderstood and misrepresented.

  • Page 54: How Stl Operates

    FX Series Programmable Controllers STL Programming 3 How STL Operates As previously mentioned, STL is a system which allows the user to write a program which functions M8002 in much the same way as a flow chart, this can be seen in the diagram opposite.

  • Page 57: Moving Between Stl Steps

    FX Series Programmable Controllers STL Programming 3 Moving Between STL Steps To activate an STL step the user must first drive the state coil. Setting the coil has already been identified as a way to start an STL program, i.e. drive an initial state. It was also noted that using an OUT statement to driving a state coil has a different meaning to the SET instruction.

  • Page 58: Using Out To Drive An Stl Coil

    FX Series Programmable Controllers STL Programming 3 3.4.2 Using OUT to drive an STL coil This has the same operational features as using SET. However, there is one major function which SET is not used. This is to make what is termed ‘distant jumps’. OUT is used for loops and jumps If a user wishes to ‘jump’...

  • Page 59: Rules And Techniques For Stl Programs

    FX Series Programmable Controllers STL Programming 3 Rules and Techniques For STL programs It can be seen that there are a lot of advantages to using STL style programming but there are a few points a user must be aware of when writing the STL sub-programs. These are highlighted in this section.
  • Page 60 FX Series Programmable Controllers STL Programming 3 • When an STL step transfers control to the next STL step there is a period (one scan) while both steps are active. This can cause problems with dual coils; particularly timers. S 30 T001 If timers are dual coiled care must be taken to T001...

  • Page 61: Single Signal Step Control

    FX Series Programmable Controllers STL Programming 3 3.5.2 Single Signal Step Control Transferring between active STL steps can be controlled by a single signal. There are two methods the user can program to achieve this result. Method 1 - Using locking devices In this example it is necessary to program separate locking devices, and the controlling signal must only pulse ON.

  • Page 62: Restrictions Of Some Instructions When Used With Stl

    FX Series Programmable Controllers STL Programming 3 Restrictions Of Some Instructions When Used With STL Although STL can operate with most basic and applied instructions there are a few exceptions. As a general rule STL and MC-MCR programming formats should not be combined. Other instruction restrictions are listed in the table below.

  • Page 63: Using Stl To Select The Most Appropriate Program

    FX Series Programmable Controllers STL Programming 3 Using STL To Select The Most Appropriate Program So far STL has been considered as a simple flow charting programming language. One of STL’s exceptional features is the ability to create programs which can have several operating modes.

Notes on using the FX-PCS/AT-EE software • Please see page 3-15 for precautions when using the FX-PCS-AT/EE software. Using STL To Activate Multiple Flows Simultaneously In the previous branching technique, it was seen how a single flow could be selected from a...
  • Page 65 FX Series Programmable Controllers STL Programming 3 When a group of branch flows are activated, the user will often either; a) ‘Race’ each flow against its counter parts. The flow which completes fastest would then activate a joining function (“First State Merge” described in the previous section) OR b) The STL flow will not continue until ALL branch flows have completed there tasks.

  • Page 66: General Rules For Successful Stl Branching

    FX Series Programmable Controllers STL Programming 3 General Rules For Successful STL Branching For each branch point 8 further branches may be programmed. There are no limits to the num- ber of states contained in a single STL flow. Hence, the possibility exists for a single initial state to branch to 8 branch flows which in turn could each branch to a further 8 branch flows etc.
