SAFETY PRECAUTIONS (Always read these instructions before using this equipment.) Before using this product, please read this manual, the relevant manuals introduced in this manual, standard PLC manuals, and the safety standards carefully and pay full attention to safety to handle the product correctly.
Page 4 [Design Precautions] DANGER When a safety PLC detects an error in an external power supply or a failure in PLC main module, it turns off all the outputs. Create an external circuit to securely stop the power of hazard by turning off the outputs. Incorrect configuration may result in an accident.
Page 5 [Installation Precautions] CAUTION Use a safety PLC in the environment that meets the general specifications described in this manual. Using this PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product. While pressing the installation lever located at the bottom of module, insert the module fixing tab into the fixing hole in the base unit until it stops.
Page 6 [Wiring Precautions] CAUTION Be sure to ground the FG terminals and LG terminals to the protective ground conductor. Not doing so could result in electric shock or erroneous operation. Use a solderless terminal with insulation sleeve for wiring of a terminal block. Use up to two solderless terminals for a single terminal.
Page 7 [Startup and Maintenance precautions] DANGER Do not touch the terminals while power is on. Doing so could cause shock or erroneous operation. Correctly connect the battery. Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery. Mishandling of battery can cause overheating or cracks which could result in injury and fires.
Page 8 [Startup and Maintenance precautions] CAUTION The online operations performed from a PC to a running safety PLC (Program change when a safety CPU is RUN, device test, and operating status change such as RUN-STOP switching) have to be executed after the manual has been carefully read and the safety has been ensured. Following the operating procedure predetermined at designing, the operation has to be performed by an instructed person.
Page 9 [Disposal Precautions] CAUTION When disposing of this product, treat it as industrial waste. When disposing of batteries, separate them from other wastes according to the local regulations. (For details of the battery directive in EU member states, refer to QSCPU User's Manual (HardwareDesign, Maintenance and Inspection).

Page 50: Numeric Values Which Can Be Used In Sequence Programs
SEQUENCE PROGRAM EXECUTION 3.7 Numeric Values which can be Used in Sequence Programs Numeric and alphabetic data are expressed by "0" (OFF) and "1" (ON) numerals in the CPU module. This expression form is called "binary code" (BIN). The hexadecimal (HEX) expression form in which BIN data are expressed in 4-bit units, and the BCD (binary coded decimal) expression form are applicable to the CPU module.
Page 51 SEQUENCE PROGRAM EXECUTION (1) Numeric value input from outside to CPU module When setting a numeric value from an external digital switch or similar device to the CPU module, BCD (binary coded decimal) can be used as the same setting in DEC (decimal) by the method given in (b).
Page 52 SEQUENCE PROGRAM EXECUTION (2) Numeric value output from CPU module to outside A digital display or similar device is available to externally display the numeric value operated by the CPU module. (a) How to output numeric value The CPU module performs operation in BIN. If binary values used in the CPU module are output as they are to a digital display, they will not displayed correctly.
Page 53: Bin (Binary Code)
SEQUENCE PROGRAM EXECUTION 3.7.1 BIN (Binary Code) (1) Binary code Binary date is represented by 0 (OFF) and 1 (ON). Decimal notation uses the numerals 0 through 9. When counting beyond 9, a 1 is placed in the 10s column and a 0 is placed in the 1s column to make the number 10. In binary notation, the numerals 0 and 1 are used.
Page 54: Hex (Hexadecimal)
SEQUENCE PROGRAM EXECUTION 3.7.2 HEX (Hexadecimal) (1) Hexadecimal notation In hexadecimal notation, 4 binary bits are expressed in 1 digit. If 4 binary bits are used in binary notation, 16 different values from 0 to 15 can be represented. Since hexadecimal notation represents 0 to 15 in 1 digit, letters A to F are used to represent the numbers 10 to 15.
Page 55: Bcd (Binary Coded Decimal)
SEQUENCE PROGRAM EXECUTION 3.7.3 BCD (Binary Coded Decimal) (1) BCD notation BCD (binary coded decimal) is a numbering system in which one digit of DEC (decimal) is expressed in BIN (binary). Though it uses 4-bit representation like hexadecimal notation, it dose not use letters to F Table3.6 shows the numeric expressions of BIN, BCD and DEC.
