Error Diagnosis and Elimination S5-95F
Erasing Cycle Time Statistics Data
Cycle time statistics data is erased
• by an overall reset
• by setting bit 6 in the control byte
Starting the Recording of Cycle Time Statistics Data
The recording of cycle time statistics data is started or resumed
• when the S5-95F is set to RUN
• by resetting bit 7 in the control byte with the programmer's "Output Address" function
Stopping the Recording of Cycle Time Statistics Data
The recording of cycle time statistics data is stopped
• when a counter reaches its maximum value of FF00
H
• by setting bit 7 in the control byte with the programmer's "Output Address" function
Note
In safety and quasi-safety mode, you cannot control the cycle time statistic when the S5-
95F is at RUN. The operating system starts the recording of cycle time statistics data in
its RESTART routine, and the function remains active.
15.8 Diagnostic Byte for Battery and Load Voltage
You can evaluate the following by querying diagnostic byte IB 35:
• The state of the backup battery
• The state of the load voltage for onboard DIs/DQs
• The state of the load voltage for counters and interrupt inputs
Diagnostic Byte IB 35
7 6 5 4 3 2 1 0
0: No battery backup
1: Battery backup OK
