Siemens S7-300/400 PLC First Line Maintenance
Course overview
Manufacturers are increasingly facing greater pressures to reduce costs, maintain efficiency whilst also maximising output. These problems are further challenged when it comes to arranging shift patterns to release essential production line staff for training.
This problem can now be eased, as we can now offer you three day courses rather than our more traditional five day courses on Siemens PLC’s. Our new three day course enables you to maintain your efficiency levels with the minimum of disruption, whilst also providing focused learning.
The Siemens S7-300/400 PLC First-line Maintenance course equips maintenance personnel with the essential knowledge & skills to identify & maintain Siemens S7-300/400 PLCs & component parts, to be able to connect a PC/PG to access & monitor the live program & to be able to perform basic maintenance duties including the backup & restore of programs.
Target Group
All engineering personnel involved with the maintenance, servicing and troubleshooting of automated controlled Siemens S7-300/400 Systems.
