Chapter 9 Troubleshooting 9_ 9-11 Error code Description CPU Status LED indicator status ERROR BUS FAULT 16#2012 Incorrect division operation (SM0/SM5). Self-defined Blinking Keep 16#2013 The value exceeds the range of values which can be represented by the floating-point numbers. (SM0/SM5) Self-defined Blinking Keep 16#2014 The task designated by TKON/TKOFF is incorrect, or exceeds the range. (SM5) Stop Blinking Keep 16#2015 There are more than 32 levels of nested program structures supported by CALL. (SM0) Self-defined Blinking Keep 16#2016 There are more than 32 levels of nested program structures supported by FOR/NEXT.
(SM0/SM5) Self-defined Blinking Keep 16#2017 The number of times FOR is used is different from the number of times NEXT is used. (SM5) Stop Blinking Keep 16#2018 There is a label after FEND, but there is no SRET. Or there is SRET, but there is no label. (SM5) Stop Blinking Keep 16#2019 The interrupt task is not after FEND. (SM5) Stop Blinking Keep 16#201A IRET/SRET is not after FEND. (SM5) Stop Blinking Keep 16#201B There is an interrupt task, but there is no IRET. There is IRET, but there is not interrupt task. (SM5) Stop Blinking Keep 16#201C End is not at the end of the program. (SM5) Stop Blinking Keep 16#201D There is CALL, but there is no MAR.
(SM5) Stop Blinking Keep 16#201E The function code used in MODRW is incorrect. (SM102/SM103) Self-defined Blinking Keep 16#201F The length of the data set in MODRW is incorrect. (SM102/SM103) Self-defined Blinking Keep 16#2020 The communication command received by using MODRW is incorrect. (SM102/SM103) Self-defined Blinking Keep 16#2021 The checksum of the command received by using MODRW is incorrect. (SM102/SM103) Self-defined Blinking Keep 16#2022 The format of the command used in MODRW does not conform to the ASCII format. (SM102/SM103) Self-defined Blinking Keep 16#2023 There is a communication timeout when MODRW is executed.
(SM102/SM103) Self-defined Blinking Keep 16#2024 The setting value of the communication timeout is invalid when RS is executed. (SM102/SM103) Self-defined Blinking Keep 16#2025 There is a communication timeout when RS is executed. (SM102/SM103) Self-defined Blinking Keep 16#2026 The interrupt number used in RS is incorrect. Self-defined Keep Keep 16#2027 The execution of FWD is abnormal. Self-defined Blinking Keep 16#2028 The execution of REV is abnormal. Self-defined Blinking Keep 16#2029 The execution of STOP is abnormal. Self-defined Blinking Keep 16#202A The execution of RSDT is abnormal. Self-defined Blinking Keep
