Siemens 840D 61363 - Channel Block: Max. no. of value lines for recording exceeded
Channel Block: Max. no. of value lines for recording exceeded
Maximum number of value lines exceeded. Alarm triggerd by following cycle: CYCLE105. Remedy: Reduce the number of value lines. Check parameter _PROTFORM[4].
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- CYCLE105 configured with excessive data recording parameters exceeding buffer capacity
- Parameter _PROTFORM[4] set to a value that requires more storage lines than available
- Insufficient memory allocation for trace/recording function in the active channel
- Multiple overlapping recording cycles or nested CYCLE105 calls consuming buffer space
Troubleshooting Steps
- 1Access the active channel's cycle parameters and locate CYCLE105 configuration in the part program
- 2Check current value of _PROTFORM[4] parameter and compare against machine documentation maximum allowable value
- 3Reduce the number of value lines in CYCLE105 by decreasing recording interval, duration, or quantity of monitored variables
- 4Clear any previous recording data or trace buffers to free available memory space
- 5Verify _PROTFORM[4] parameter is set appropriately for your application requirements and re-execute the program
