Chapter 3 PLC System Configuration & Settings Enable: The current states and values of devices are retained. Disable: The states and values of devices are cleared to default value. Y Keeps outputting when RUN --> STOP Set the state of Y device when the state of CPU is switched between RUN and STOP. Off ： All Y devices are set to OFF. Retain Present State: The states of the Y devices are retained. I/O allocation setting when Power On The actual I/O module configuration is read automatically when the CPU module is powered ON. Or the CPU module operates based on the configuration set manually in HWCONFIG. Auto:
Operates based on actual connected modules without any module and parameters set. Manual: Operates based on the configuration set in HWCONFIG. applications, you can simply use special flags to mark which I/O module will NOT be used to meet Manual + Flag: Select this option, you need to use it with flags SM230-SM261. For less module the actual I/O module placement. In this mode, you can use the same PLC program and download the I/O allocation table once for various I/O applications. Select Action when I/O Module parameter with Manual CONFIG Different The parameter cannot be set unless the Manual option is selected in the above parameter I/O module CONFIG by Auto/Manual when Power On .
Auto update: The CPU module will update its configurations based on the actual module configurations. CPU alarm: The CPU module shows a warning when an error occurs. CPU module Stop when I/O Module No Response The parameter sets whether the CPU and other normal modules can operate constantly when there is a expansion module, which does not response when offline. Stop: The CPU module stops running and gives errors. 3-85
