Scope

General configuration covers IOC/bootstrap behavior that is not axis-specific:

• startup mode and global macros
• record update/processing behavior
• iocsh utility functions
• common data buffering patterns
• command-parser reference access

By Task

Start and parameterize ecmccfg

• startup.cmd for startup arguments/macros and initialization behavior.
• modes for FULL, DAQ, NO_MR, and ENG_MODE.

Configure EPICS record processing/update rate

• PV Processing Rate for ECMC_SAMPLE_RATE_MS, per-record overrides, and processing hooks.

Use utility functions in startup scripts

• iocsh utilities for ecmcEpicsEnvSetCalc, ecmcIf, loops, and file existence checks.
• Script Reference for which scripts/ entry points are public, advanced, or internal helpers.
• Startup Validator for checking startup syntax, script macros, and local file references before IOC execution.
• ESI Parser for the legacy EtherCAT ESI XML utility.
• Advanced EtherCAT and Commissioning for extra domains, data items, DC, slave verify, and topology skips.
• EtherCAT Endpoint Timing for input/output delay, DC phase, timestamps, timing PVs, and the diagnostic panel.
• Verify DC Timing with Position Compare for an EL2252 output checked by an EL7062/ED7062 touch probe.
• FSoE and TwinSAFE for direct safety-telegram forwarding and hardware-panel navigation.
• Axis Groups for named axis collections used by mc_grp_... PLC helpers.
• Master/Slave State Machine for synchronized virtual/physical systems.
• Lookup Tables for loading numeric correction/value tables into ecmc.

Configure generic data capture/buffering

• data storage buffer for ds_append_data/ds_push_asyn usage patterns.

Apply platform-level recommendations

• best practice for EtherCAT rate and host-side setup guidance.

Browse command API details

• ecmc command reference for command syntax by domain.
