System Architecture & Signal Flow
The A03B-0815-C003 connects to the FANUC CNC main controller via the I/O Link serial bus (JD1A/JD1B connectors). The module receives group address assignments from the CNC parameter table, allowing the controller to map physical I/O points to PMC (Programmable Machine Controller) addresses. Signal flow is unidirectional per channel (input or output), with optocoupler isolation protecting the CNC backplane from field-side voltage transients. Typical configuration involves assigning the module to a specific I/O group within the PMC I/O address map (X/Y addresses), verified via FANUC LADDER III or equivalent diagnostic software.

Technical FAQ
Q: Is the A03B-0815-C003 compatible with FANUC Series 0i controllers?
A: No. This module is designed for the Series 15/16/18/21 I/O Link architecture. Series 0i uses a different I/O Link II protocol and requires A03B-0819-series modules.
Q: Can this module be used with a FANUC PMC-M or PMC-L ladder program?
A: Yes. The module is transparent to the PMC ladder type. Address mapping is configured via CNC parameters regardless of PMC model.
Q: What is the maximum number of A03B-0815-C003 modules per CNC system?
A: The maximum depends on the I/O Link group capacity of your specific CNC model. Consult your FANUC maintenance manual (B-series) for the I/O Link group limit.
Q: Do you provide a test report with each unit?
A: Yes. A pre-shipment inspection report is available upon request at no additional charge.
Q: What is the lead time if the unit is out of stock?
A: Typical sourcing lead time is 5–15 business days. Contact us for real-time availability.
