Summary
This driver provides access to EZPLC memory using a mix of discrete and register-based addressing:
Key Concepts
-
Discrete I/O:
- I, O, S, SD
-
Register Types:
- IR, OR, R, SR, XR, XS
- Extended/special registers: #R, #S
Practical Takeaways
- Straightforward memory model similar to PLC-style addressing
- Supports both bit-level (discrete) and word-level (register) data
- Extended register sets (#R, #S) give access to additional controller memory
👉 In practice:
- Use I/O prefixes (I, O) for field signals
- Use R / IR / OR for logic and data storage
- Use extended registers (#R / #S) when working with advanced or expanded memory areas
