AH500 Programming Manual 7-6 Error code Description CPU Status LED indicator status ERROR BUS FAULT 16#2014 The task designated by TKON/YKOFF 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. 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 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. (SM120/SM103) Self-defined Blinking Keep 16#2024 The setting value of the communication timeout is invalid. (SM120/SM103) Self-defined Blinking Keep 16#2025 There is a communication timeout when RS is executed. (SM120/SM103) Self-defined Blinking Keep 16#2026 The interrupt number used in RS is incorrect.
