# EAE SE Process Libraries Reference

Reference skill for the **SE.App2Base** and **SE.App2CommonProcess** libraries - the standard industrial process control libraries in EcoStruxure Automation Expert.

**These libraries provide:**
- Signal processing (analog/digital I/O)
- Motor and valve control
- PID and process control
- Equipment modules (pumps, flow control)
- Interlocks, failures, permissives
- HMI-ready CATs with faceplates

> **Note:** SE.App2CommonProcess depends on SE.App2Base and Runtime.Base.

## Quick Start

```
User: I need a PID controller block
Claude: Use `PID` from SE.App2CommonProcess - a standard PID with auto/manual modes

User: What block handles analog input scaling?
Claude: Use `AnalogInput` CAT or `AISignalScaling` from SE.App2Base
```

## Triggers

- `/eae-se-process`
- "find process block"
- "motor control block"
- "valve control block"
- "PID block"
- "analog input block"
- "SE.App2Base"
- "SE.App2CommonProcess"

```bash
# Find motor-related blocks
python scripts/lookup_block.py "motor"
# Returns: Motor, Motor2D, Motor2S, MotorCyc, MotorVs, motorLogic, etc.

# Find all PID blocks
python scripts/lookup_block.py "pid"

# Show category with results
python scripts/lookup_block.py "valve" --category

# Show library (App2Base vs App2CommonProcess) with results
python scripts/lookup_block.py "alarm" --library

# List all categories
python scripts/lookup_block.py --list-categories

# List all blocks

## Common Usage Patterns

See [common-patterns.md](references/common-patterns.md) for detailed patterns:

1. **Basic Analog Input** - AnalogInput with scaling and alarms
2. **Motor with Interlocks** - Motor CAT with ilckCondItem chain
3. **PID Control Loop** - PID with cascade mode
4. **Valve with Permissives** - Valve2Op with permCondItem chain
5. **Equipment Module** - PumpSet with FlowCtl coordination
