Please define the PLC-hardware used within your station with the STEP 7 software.
After the configuration, please download it into the PLC.
Information
Please make sure that the PC is connected to the PLC with the communication cable,
the power supply of the station is on, the emergency switch is deactivated and the
CPU-switch is in STOP position. Make sure that the PLC memory is empty (delete).
Use the screen shots (execution) to proceed.
Open a new project and name it
P2_01 . It´s not necessary to add the station name
into the hardwareconfiguration name, because the configuration is the same for all
stations.
Instructor: Show how to delete the contents of a CPU using the switch of the CPU.
Let all the participants try it several times. Explain them where to find the name of
the PLC-modules (on the top of the module, for example SM 323) and the order-
number (6ES7……..) and explain why this order-number is so important for the
hardwareconfiguration. Explain also what a Clock Memory is and what Retentive
Memories are and why it´s better to switch them to 0.
Planning
Please follow the description (screen shots) carefully step by step. Please make
sure, that every member of your team did the hardwareconfiguration at least once.
The time to finish this project should be around 1,0 hours.
