PLC Maintenance of SMTCL cnc Machine Tools

PLCs are typically maintained every three years, with the following procedures: back up the program, clean the machine, then dry it, and primarily inspect the power sections of each module as well as the input and output sections for any underperforming components. Before operating, the CPU module must be cleaned to reduce static electricity. Finally, verify that the battery capacity is normal; if the capacity has decreased, it is best to power it off and replace it.
