In this manual, SAFETY PRECAUTIONS are classified into 2 levels: "DANGER" and "CAUTION". Indicates that incorrect handling may cause hazardous conditions, resulting in DANGER death or severe injury.
Page 4 [DESIGN PRECAUTIONS] DANGER If load current more than the rating or overcurrent due to a short circuit in the load has flowed in the output module for a long time, it may cause a fire and smoke. Provide an external safety device such as a fuse.
Page 5 [INSTALLATION PRECAUTIONS] CAUTION Use the programmable controller under the environment specified in the user's manual. Otherwise, it may cause electric shocks, fires, malfunctions, product deterioration or damage. Insert the module fixing projection into the fixing hole in the base unit and then tighten the module fixing screw within the specified torque.
Page 6 [WIRING PRECAUTIONS] DANGER Be sure to shut off all phases of the external power supply used by the system before wiring. Failure to do so may result in an electric shock or damage of the product. Before energizing and operating the system after wiring, be sure to attach the terminal cover supplied with the product.
Page 7 [STARTUP AND MAINTENANCE PRECAUTIONS] DANGER Do not touch any terminal during power distribution. Doing so may cause an electric shock. Properly connect batteries. Do not charge, disassemble, heat or throw them into the fire and do not make them short-circuited and soldered.
Page 8 CAUTION When performing online operations (especially, program modification, forced output or operating status change) by connecting a peripheral device to the running CPU module, read the manual carefully and ensure the safety. Incorrect operation will cause mechanical damage or accidents. Do not disassemble or modify each of modules.

Page 56: Overview Of Operation Processing
CPU MODULE 4.1.1 Overview of operation processing The following shows an overview of processing which begins with a CPU module power- on to execute the sequence program. CPU modules processing may be categorized roughly into the following four kinds: Initial processing This is a preprocess to execute sequence operations, and is performed only once upon power-on or reset.
Page 57 CPU MODULE (d) Executes the refresh processing when there is a refresh request from the network module or link module. Note that the AnSHCPU can enable and disable execution of link refresh by turn- ing ON/OFF M9053 and by issuing DI/EI instructions. (e) When the trace point setting of sampling trace is set for each scan (after END instruction execution), stores the device status for which it is setup into the sampling trace area.
Page 58 CPU MODULE POINT When executing the FROM/TO instruction for the special function module frequently in short scan time, it may cause an operation error in the target special function module. When executing the FROM/TO instruction, match the processing time and conversion time for the special function module using timer or constant scan function.
