Page 25: 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 26: 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.

SFC. This is not a coincidence as this programming technique has been developed deliberately to achieve an easy to program and monitor system. One of the key differences to Mitsubishi’s STL programming system is that it can be entered into a PLC in 3 formats. These are: Ι) Instruction - a word/mnemonic entry system...
Page 52: Each Step Is A Program
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 53: How To Start And End An Stl Program
SET or just included in an OUT S 22 instruction. However, within Mitsubishi’s STL programming language an STL coil which is SET S 27 SET has a different meaning than one that is included in an OUT instruction.
Page 54: Terminating An Stl Program
FX Series Programmable Controllers STL Programming 3 Initial Steps For an STL program which is to be activated M8002 on the initial power up of the PLC, a trigger SET S005 similar to that shown opposite could be used, X001 i.e.
Page 55: 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 56: 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 57: 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 58 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 59: 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 60: 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 61: 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.
Page 62: Using Stl To Activate Multiple Flowssimultaneously
FX Series Programmable Controllers STL Programming 3 Limits on the number of branches • Please see page 3-14 for general notes on programming STL branches. 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 63 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 64: 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.

Various timer resolutions are possible, from 1 to 100 msec, but availability and quantity vary from PLC to PLC.
Page 88: General Timer Operation
FX Series Programmable Controllers Devices in Detail 4 4.9.1 General timer operation Timers operate by counting clock pulses (1, 10 and 100 msec). The timer output contact is activated when the count data reaches the value set by the constant K. The overall duration or elapsed time, for a timers operation cycle, is calculated by multiplying the present value by the timer resolution, i.e.
Page 89: Retentive Timers
FX Series Programmable Controllers Devices in Detail 4 4.9.3 Retentive Timers A retentive timer has the ability to retain the currently reached present value even after the drive contact has been removed. This means that when the drive contact is re-established a retentive timer will continue from where it last reached.

If some of these techniques are applied to user programs the user must ensure that they will perform the task or operation that they require. Mitsubishi Electric can take no responsibility for user programs containing any of the examples within this manual.
Page 420: Using The Forced Run/Stop Flags
FX Series Programmable Controllers Points Of Technique 10 10.3 Using The Forced RUN/STOP Flags 10.3.1 A RUN/STOP push button configuration The FX programmable controller has a single RUN terminal. When power is applied to this terminal the PLC changes into a RUN state, i.e. the program contained is executed. Consequently when there is no power 'on' the RUN terminal the PLC is in a STOP state.
Page 421: Remote Run/Stop Control

Page 428 FX Series Programmable Controllers Points Of Technique 10 This example uses the IST instruction (FNC 60) to control the operation mode of the robot arm. The program shown opposite identifies how the IST instruction is written into the main program. When the IST instruction is used there are 5 selectable modes which access three separate p r o g r a m s .

Once 'Z Return' has been selected from the Ensure 'dowm' and 'clamp' mode selection screen the bit device M35 is RST Y1...
Page 430 FX Series Programmable Controllers Points Of Technique 10 In this example these three modes are selected by an external rotary switch. The rotary switch is not connected to the PLC but to the I/O bus on the rear of the DU unit. The use of the rotary switch means that the selected modes are mutually exclusive in their operation.
Page 431 FX Series Programmable Controllers Points Of Technique 10 Points of interest: a) Users of the IST instruction will be aware that only one of the operation modes should be active at one time. In this example program the isolation of 'Manual' and 'Zero return' modes by the use of separate DU control screens, and the use of a rotary switch to isolate the three automatic modes achieves this objective.
