Page 43: Counting Step Number
Counting Step Number The number of steps in basic instructions and application instructions of the safety CPU module may increase depending on the devices to be used.

Page 44: Operation When Out, Set/Rst, Or Pls/Plf Instructions Use The Same Device
Operation when OUT, SET/RST, or PLS/PLF Instructions Use the Same Device The following describes the operation for executing multiple instructions of OUT, SET/RST, or PLS/PLF that use the same device in one scan. (1) OUT instructions using the same device Do not program more than one OUT instruction using the same device in one scan.
Page 45 (2) SET/RST instructions using the same device (a) The SET instruction turns ON the specified device when the execution command is ON and performs nothing when the execution command is OFF. For this reason, when SET instructions using the same device are executed two or more times in one scan, the specified device will be ON if any one of the execution commands is ON.
Page 46 (3) PLS instructions using the same device The PLS instruction turns ON the specified device when the execution command is turned ON from OFF. It turns OFF the device at any other time (OFF to OFF, ON to ON, or ON to OFF). If two or more PLS instructions using the same device are executed in one scan, each instruction turns ON the device when the corresponding execution command is turned ON from OFF and turns OFF the device in other cases.
Page 47 • The X0 and X1 turn ON from OFF at the same time. M0 is turned ON because M0 is turned OFF X1 goes OFF because X1 is other (M0 remains ON.) than OFF ON status. (M0 remains OFF.) M0 is turned ON because M0 is turned OFF because X0 is other X0 goes OFF than OFF...
Page 48 [Timing Chart] • The ON/OFF timing of the X0 and X1 is different. (The specified device does not turn ON throughout the scan.) M0 is turned OFF because X1 is other than ON OFF status. M0 is turned OFF because (M0 remains OFF.) X1 is other than ON OFF status.

Page 92 MC, MCR Program Example (1) The master control instruction can be used in nesting. The different master control regions are distinguished by nesting (N). Nesting can be performed from N0 to N14. The use of nesting enables the creation of ladders which successively limit the execution condition of the program.
Page 93 MC, MCR Cautions when Using Nesting Architecture (1) Nesting can be used up to 15 times (N0 to N14) When using nesting, nests should be inserted from the lower to higher nesting number (N) with the MC instruction, and from the higher to the lower order with the MCR instruction. If this order is reversed, there will be no nesting architecture, and the safety CPU module will not be capable of performing correct operations.

Page 196: Canceling Errors
Canceling Errors CPU module can perform the cancel operation for errors only when the errors allow the CPU module to continue its operation. To cancel the errors, follow the steps shown below. 1) Read the special register SD81 with GX Developer and confirm the cause of the continuation error that currently occurs in the CPU module.
Page 197 1. When the error is canceled with the error code to be canceled stored in the SD50, the lower one digit of the code is neglected. (Example) If error codes 2100 and 2106 occur, and error code 2100 to cancel error code 2106.

Page 200: Appendix 1 Operation Processing Timea Appendix 1.1Definition
Appendix 1 OPERATION PROCESSING TIME Appendix 1.1 Definition (1) Processing time taken by the QSCPU is the total of the following processing times. • Total of each instruction processing time • END processing time • I/O refresh time • Service processing time (2) Instruction processing time This is the total of processing time of each instruction shown in Appendix 1.2.
Page 201 Appendix 1 OPERATION PROCESSING TIME Appendix 1.2 Operation Processing Time The processing times for the individual instructions are shown in the table on the following pages. Operation processing times can vary substantially depending on the nature of the sources and destinations of the instructions, and the values contained in the following tables should therefore be taken as a set of general guidelines to processing times rather than as being strictly accurate.

Page 209: Appendix 2 Special Relay List
Appendix 2 SPECIAL RELAY LIST Special relays, SM, are internal relays whose applications are fixed in the Programmable Controller. For this reason, they cannot be used by sequence programs in the same way as the normal internal relays. However, they can be turned ON or OFF as needed in order to control the CPU module and remote I/O modules.
