Data Layer Control
Main Node
he/commsw/app/tool1 exposing command, state, lastResult.
Write command to set pset and pulse enable (rising edge loads PSet; falling edge aborts active tightening). Continuous enable not supported.
Errors (missing PSet, transfer failures, unlicensed software) reported through state node with error_code field. Negative error codes block Enable/Disable commands. See Error Codes Reference for complete list of error codes and resolutions.
Buffer Status Monitoring
he/commsw/buffer/status - Output buffer statistics for monitoring HTTP transmission health:
queued_items- Number of results awaiting transmissiontotal_transmitted- Lifetime successful transmissionsavailable_disk_space_mb- Available storage spaceis_disk_space_critical- True when storage critically low
See Output Curves - DataLayer Integration for complete field descriptions and PLC monitoring patterns.



Summary
command: write (pset + enable edge)state: read (connection/operational)lastResult: read (torque/angle/result JSON)
