PLC2500 FAT
The group discussed challenges with the control system implementation in the plant, including
time differences, video and audio issues, and the need for a clear and concise HMI design.
Speaker 3 emphasized the importance of a complete and accurate representation of the process in
the software. Speaker 4 mentioned potential issues with the PLC program crashing. Speaker 6
brought up the issue of missing or unclear pin connections, and Speaker 7 apologized for internet
connectivity issues. The group also discussed the importance of confirmation for each step in the
FFC sequence and explored the possibility of adding a skip button or confirmation for each step.
Speaker 1 and Speaker 4 also explored the idea of modifying the two-minute required time for
the first startup, while Speaker 6 raised concerns about the need for access to the operator.
