Chapter 3 PLC System Configuration & Settings Users can identify a device by means of the name of the device. When several devices are connected to one network, users can check whether a device connected to the computer is the device they expect by checking the device name. To prevent errors, when users are downloading or uploading data or operating online, the system will check whether the label name of the PLC CPU and the label name in the Project section is the same or not, when the name of the CPU module is different from the name attached to the model in the project management area.
The following image is the System Parameter setting page that provides drop-down lists to choose or box to input appropriate parameter values. Clear Non-latched Device (STOP --> RUN) If the Clear Non-latched Devices checkbox is selected, the states of the non-latched devices and the values in the non-latched devices will be cleared when the CPU module begins to run. Y state (STOP RUN) When the CPU module begins to run, the states of the Y devices are OFF, retained, or restored to the states before the CPU module’s stopping running. Clear : Set all Y device output to OFF. Retain Present State : Output retain to present state. Previous State before STOP :
