Note:
The Event column in the log file indicates that the switching output was active at the specified time in the completed
firing program. This function is not available on the ST 310 controller and is therefore always displayed as “0”.
8.3.10. Saving on USB flash drive
The control system does not overwrite any files that have already been created on the inserted USB flash drive. It is
therefore recommended to regularly transfer created files from the USB stick to the respective computer to save the
files for evaluation and not to exceed the storage capacity of the USB flash drive.
8.4. ROHDEgraph
8.4.1. General information
