Diagnostic LED

To control the Diagnostic LED by user program open the “Program-Control” instruction and use the function DIAG_LED in you S7-200 User program.

DIAG_LED: To control the Diagnostic LED by user program.

IN: Byte address. So you can use 8 binary addresses at the same time.

Tip: A flashing in different frequencies is possible so you can separate different diagnostic conditions.

Additional questions:

1. Can I record the data with Microsoft Excel?No, this is a Online-feature like the status of the status chart. To record some data you better use the Data Logging wizard and a new MC-card.

2. Can I use it also with the current S7-200 PLC’s?Yes, the trend chart is also working with the current S7-200 PLC’s.

3. I know my signal is changing but I only see a line. What’s wrong?The time base (update rate) of the trend chart is to slow or the signal is changing faster than 0.5 seconds.

4. Can I use the trend chart via modem/Ethernet?Yes, the trend chart is working if you can connect to the PLC via Micro/WIN V4.Diagnostic/Debug
