One aluminium workpiece shall come from a previous station and inserted into the
Handling Station, checked that the workpiece is not black and moved to the
following station.
After mechanical connection of the previous station and the following station, the
CPU have to be set to RUN and the light barrier signal will be sent to the previous
station.
Before starting, the station have to be in home position (use Project 2.15). The
homing position process can only be started, if the following station is in place (light
barrier signal).
After pressed the Start-button shortly at each station, the cycle starts. but only if the
following station have been started already and is ready to take a workpiece.
Information
Please edit the program FC1 in FBD which starts without any condition. Edit with
symbols. Use the list of inputs and outputs from Project 1.3 to find necessary
informations. The OB1 is in STL.
Instructor: Please explain very clearly what you want to have – if home-position is
running it´s not able to Start, if Start-condition is running it´s not able to run the
home-position sequence. Discuss within the whole team, how to start the cycle
step by step which means, which station have to be started first, second a.s.o.
Please do the planning together with the participants. Go ahead step by step and
show always the condition and the action at the station directly. Explain to the
participants, why a connected station is creating a 0-signal at the light barrier.
Discuss the communication handshake together with all teams. Make sure, this
project is not longer than 3,0 hours.
Planning
Please plan your project step by step first within the whole team for one station first.
Use your program from Project 2.15 as a base for this project. Plan your
communication with the other team carefully. Please make sure, that the
communication input 1 (following station started and ready) is on as long as the
workpiece is inserted into the following station. Discuss with the team of the
following station also, that they have to wait for the communication output 1
(communication input 1 at the following station) to start their process.
The time to finish this project should be around 3,0 hour.
