Page 28: Chapter 2 System Architecture
Chapter 2 System Architecture Single-Unit System of FB -PLC The Single-Unit system means a system built only by a single FBs-PLC and its expansion unit/modules and communication boards/modules. Such system have a limited capability (refer), beyond that capability can incorporate CPU communication via LINK function for expansions (please refer to the next paragraph).
Page 29: Connection Of Multiple Fbs-Plc
Regarding communication resources, the FBs-PLC hardware can accommodate up to 5 communication ports (with a maximum speed of 921.6Kbps). In addition to providing the standard FATEK communication protocol, it also supports the Modbus master/slave protocol or any user-defined protocol. This functionality easily renders the connections with intelligent peripherals such as electronic scale, bar code reader, and various meters and gauges.
Page 30: Connection Of Fbs-Plc With Host Computer Or Intelligent Peripherals
Connection can be established as long as the upper-level computer or intelligent peripherals use either one of the two protocols. In the application, in which driver for FATEK or Modbus is not available, FATEK also provide standard DDE communication server, which enables FBs-PLC to connect with any computer system supporting DDE.
Page 31: Chapter 3：Expansion Of Fbs-Plc

Page 41: Precautions On Construction And Wiring
4.5 Precautions on Construction and Wiring 1. During the wiring of FB –PLC, please follow local national standards or regulations for installation. 2. Please chose the wires with proper wire gauge for I/O wiring according to the current loads. 3. Shorter wires are preferred. It is advised that the length of I/O wiring does not exceed 100m (10m for high-speed input).
Page 42 Chapter 5 Power Supply Wiring, Power Consumption Calculation, and Power Sequence Requirements -PLC internally has three kinds of circuit: a 5VDC logic circuit, a 24VDC output circuit, and a 24VDC input circuit. They are all powered by the built-in power supply of main/expansion units. Expansion modules other than main/expansion units do not contain any power supply and are powered by the power supply inside the main/expansion units or expansion power supply (FB -EPOW).
Page 43  Note The schematic diagram of AC power supply wiring in main/expansion units is shown below. Also be cautious about the following: Please follow the wiring schemes regulated by local national standards to use single-pole switch（break hot wire 〝L〞）, or double-pole switch（break both〝L〞and〝N〞）, to turn on or off the AC input power. In wiring, hot wire〝L〞must be connected to the L terminal on unit, while the ground line〝N〞connected to the terminal.

Page 45: Residual Capacity Of Main Unit/Expansion Unit
5.3 Residual Capacity of Main/Expansion Unit & Current Consumption of Expansion Module Besides its own circuits usage, the residual capacities of three sets of built-in power supply of main/expansion unit are big enough for other expansion modules usage. In addition, the expansion power (FB -EPOW) module can also provides the power for expansion modules usage.
Page 46: Maximum Current Consumption Of Expansion Module
5.3.2 Maximum Current Consumption of Expansion Module Without its own power supply, expansion modules must be supported by the main/expansion unit, expansion power, or external power supply (24VDC input circuit alone). The following table lists the maximum consumption current of each expansion module.
Page 47 5.4 Requirement of Power Sequence in Main Unit & Expansion Unit/Module When the power is on, the FB -PLC main unit first detects the type and number of expansion unit/module attached to its expansion interface and get the actual I/O configuration. Therefore, while the main unit performs detection, the power in expansion unit/module should be already UP, otherwise, the detected I/O configuration will not correct.

【Instruction】 Chapter 1 PLC Ladder Diagram and the Coding Rules of Mnemonic In this chapter, we would like to introduce you the basic principles of ladder diagram, in addition, the coding rules of mnemonic will be introduced as well, it's essential for the user who use FP-07C as a programming tool. If you are familiar with PLC Ladder Diagram and mnemonic coding rules, you may skip this chapter.
Page 64: Sequential Logic
Conventional Ladder Diagram PLC Ladder Diagram circuit 1 circuit 1 circuit 2 circuit 2 circuit 3 circuit 3 The above example illustrated the combination logic using the actual wiring diagram, conventional Ladder Diagram, and PLC Ladder Diagram. Circuit 1 uses a NO (Normally Open) switch that is also called "A" switch or contact. Under normal condition (switch is not pressed), the switch contact is at OFF state and the light is off.
Page 65: Differences Between The Conventional And Plc Ladder Diagram
Conventional Ladder Diagram PLC Ladder Diagram When we first connect this circuit to the power source, X6 switch is ON but X5 switch is OFF, therefore the relay Y3 is OFF. The relay output contacts 1and 2 are OFF because they belong to A contact (ON when relay is ON). Motor does not run. If we press down the switch X5, the relay turns ON as well as contacts 1and 2 are ON and the Motor starts.

Page 68 We must energize the coil of relay first (using OUT instruction) in order to turn on the relay. After the coil is energized, its contact status will be ON too. As shown in the example above, if Y0 turns ON, then the relay contact A is ON and contact B is OFF, TU contact only turns ON for one scan duration and TD contact is OFF.
Page 69 Node: The connection point between two or more elements（please refer to section 5.3） Block: a circuit consists of two or more elements. There are two basic types of blocks: • Serial block：Two or more elements are connected in series to form a single row circuit. Example: •...
Page 70: The Coding Rules Of Mnemonic
Network: Network is a circuit representing a specified function. It consists of the elements, branches, and blocks. Network is the basic unit in the Ladder Diagram which is capable of executing the completed functions, and the program of Ladder Diagram is formed by connecting networks together. The beginning of the network is the origin line.
Page 71 Remark 2: Also using the AND instruction directly if an OUT TR instruction has been used at a branch line to store the node statuses. Example: OUT TR OUT TR0 LD TR0 LD TR Using AND instruction for serial connection of a single element. Example: Using OR instruction for parallel connection of a single element.
Page 72 ANDLD instruction is used to connect parallel blocks in series. Example: ORLD Must use ANDLD instruction ANDLD The ANDLD instruction must be used if the element or serial block is in front of the parallel block. If the parallel block is in front of the element or serial block, AND instruction can be used to connect all parts together.
Page 73: The De-Composition Of A Network
1.5 The De-Composition of a Network (Users of WinProladder can skip this section) The key process of de-composition of a network is to separate the circuits that appear between two vertical lines into independent elements and serial blocks, then coding those elements and serial blocks according to the mnemonic coding rules and then connect them (with ANDLD or ORLD instruction) from left to right and top to bottom to form a parallel or a serial-parallel blocks, and finally to form a complete network.
Page 74: Using Temporary Relays
1.6 Using Temporary Relays (Users of WinProladder can skip this section) The network de-composition method for mnemonic coding demonstrated in section 1.5 does not apply to the branched circuit or branched block. In order to input the program using the method shown in section 1.5, It must first to store the statuses of branched nodes in temporary relays.

Page 76 When a single element or a serial block is connected in parallel with a parallel block, ANDLD instruction can be omitted if put the parallel block in front. ORLD ANDLD If the branch node of a branch circuit is directly connected to the output coil, this coil could be located on top of the branch line (first row) to reduce the code.

Page 106: Sequential Instructions
Chapter 4 Sequential Instructions The sequential instructions of FBs-PLC shown in this chapter are also listed in section 3.1. Please refer to Chapter 1, "PLC Ladder diagram and the Coding rules of Mnemonic instruction", for the coding rules in applying those instructions. In this chapter, we only introduce the applicable operands, ranges and element characteristics, functionality.

FUN7 is the UDCTR function. While rising edge of CK input occur, FUN7 will count up if the U/D status is 1 or count down if the U/D status is 0. The example shown above, U/D status is fixed at 1 since U/D is directly connected from the origin-line to a SHORT contact, therefore FUN7 becomes an Up counter.
Page 110: Set Coil And Reset Coil
From the above example, if turn the X0 "ON" then "OFF", Y0 will keep at "ON". When change the PLC state from RUN to STOP then RUN or turn the power off then on, the Y0 still keep at ON state. But if use the OUT Y0 instruction instead of the OUT L Y0 , Y0 status will be OFF.

Page 112: Chapter 5: Description Of Function Instructions
Chapter 5 Descriptions of Function Instructions 5.1 The Format of Function Instructions In this chapter we will introduce the function instructions of FBs-PLC in details. All the explanations for each function will be divided into four parts including input control, instruction number/name, operand and function output. If use the FP-07 to input the mnemonic instruction, except for the T, C, SET, RST and SFC instructions that can be entered directly by pressing a single key stroke on FP-07, other function instructions must be entered by key in the instruction number rather than the instruction name.
Page 113: Instruction Number And Derivative Instructions
All input controls of the function instructions should be connected by the corresponding elements, otherwise a syntax error will occur. As shown in example 3 below, the function instruction FUN7 has three inputs and three elements before FUN7. ORG X0, LD X1 and LD X2 corresponds to the first input CK↑, second input U/D and third input CLR. Example 3: Ladder Diagram FP-07 Mnemonic code...
Page 114: Operand
Remark: In order to differentiate between 16-bit and 32-bit instructions while using the ladder diagram and mnemonic code, we add the postfix letter D after the "Instruction number" to represent 32-bit instructions and the size of their operand are 32-bit as shown in example 4 on P.6-6. The instruction FUN 11D has a postfix letter D, therefore the source and destination operands need to prefix a letter D as well, such as the augend Sa : R0 is actually Sa=DR0=R1-R0 and Sb=DR2=R3-R2.
Page 115 The names and functions of the major operands: Abbreviation Name Descriptions The data of source (S) operand are only for reading and reference and will not be Source changed with the execution of the instruction. If there are more than one source operands, each operand will be identified by the footnote such as Sa and Sb.

Page 117: Functions Output (Fo)
5.1.4 Functions Output (FO) The “Function Output” (FO) is used to indicate the operation result of the function instruction. Like control input, each function outputs shown in the screen of programming software are all attached with a word which comes from the abbreviation of the output functionality.
Page 118 As shown in the above diagram, you only need to change the V value to change the operand address. After combining the index addressing with the FBs-PLC function instructions, a powerful and highly efficient control application can be achieved by using very simple instructions. Using the program shown in the diagram below as an example, you only need to use a block move instruction (BT_M) to achieve a dynamic block data display, such as a parking management system.

Page 120: Numbering System
 Warning 1. Although using pointer register for indirect addressing application is powerful and flexible, but changing the V and Z values freely and carelessly may cause great damages with erroneous writing to the normal data areas. The user should take special caution during operation. 2.
Page 121 ● Floating Point Number: The format of floating point number of Fatek-PLC follows the IEEE-754 standard, which use a double word for storage and can be expressed as follow: floating point number = sign + Exponent + Mantissa ▲ If the sign bit is 0 the number is positive, if the sign bit is 1 the number is negative.
Page 122: The Coding Of Numeric Numbers For Fbs-Plc
5.3.2 The Coding of Numeric Numbers for FBs-PLC FBs-PLC use the binary numbering system for its internal operations that is the data of external BCD inputs must be converted to binary number before the PLC can process. As we know the binary code is very difficult to read and input to the PLC for human, therefore FP-07 and WinProladder use the decimal unit or hexadecimal unit to input or to display the data.
Page 123: Representation Of Negative Number
5.3.5 Representation of Negative Number (Beginners should skip this section) As prior discussion, when the MSB is 1, the number will be a negative number. The FBs-PLC negative numbers are represented by 2’S Complement, i.e. to invert all the bits (B15～B0 or B31～B0) of its equivalent positive number (The so-called 1’S Complement is to change the bits equal 1 to 0 and the bits equal 0 to 1) then add 1.

Page 125 (difference) obtained from addition (subtraction) is different from the usual negative number representation. When the operation result is a negative value, 0 can never appear in the MSB of the sum (difference) operand. The carry flag represents the positive value 32768 (2147483648) and the borrow flag represents the negative value −32768 (−2147483648).

The benefits are high readability, easy maintenance, convenient updating and high quality and reliability. For the control applications, consisted of many sequential tasks, designed by conventional ladder program design methodology usually makes others hard to maintain. Therefore, it is necessary to combine the current widely used ladder diagrams with the sequential controls made especially for machine working flow.
