CNC Loading Robot
Protocol Linkage Replaces Wireless I/O

II. Core Pain Points

The "handshake" between robot and CNC has long been the weak link of automated production lines.

• Communication relies on wireless I/O modules — complex wiring, prone to failure: The traditional approach adds a wireless I/O module behind each CNC, triggering actions (door open/close, blow, machining) via different I/O points. Modules require on-site wiring, pairing and address setup; deployment is cumbersome, and wireless signals are vulnerable to workshop EMI with occasional dropouts. Failure points are scattered across 10 CNC × N I/O points.
• Can only trigger simple functions, cannot sense internal CNC status: Wireless I/O only gets limited on/off signals like "door open / door closed". It cannot read the CNC current mode, progress, alarm codes or active program number — the robot can only "operate blind", waiting on fixed delays, with conservative cadence and low efficiency.
• Cannot perform complex logic control: Limited by I/O point count, only simple on/off actions are possible. Any process-conditional branching, macro calls or stage-based linkage forces a fallback to manual operation.
• Program changes rely on manual copying — breaks at the "last mile": CNC programs are still copied in via USB/CF card manually. Program changes mean downtime. Although loading/unloading is automated, program management, first-piece confirmation and exception handling still depend on people — the line is never truly "fully automated".
• Maintenance black box: The 10 wireless I/O modules operate independently with no unified monitoring or remote diagnosis; when something fails, staff must go to each machine to troubleshoot one by one.

III. Why Traditional Approaches Fail

Wireless I/O, constrained by its inherent architecture, cannot support protocol-level linkage that "sees status and controls actions".

• Wireless I/O is essentially "remote on/off triggering" with no data-plane connection to the CNC — it cannot read or write internal CNC registers, locking control dimensions at "on/off".
• The workshop complex EMI environment causes occasional wireless link dropouts that fail the "handshake", causing cadence chaos or even collision risk — stability cannot match continuous production requirements.
• Program changes still require manual USB copying; automation ends abruptly at the "last mile". The 10 wireless modules have no unified management, making fault location and remote O&M impossible.

IV. Solution: AIS-G160 Protocol Linkage

Connect directly via native CNC protocol instead of wireless I/O; use register read/write and program up/download to close the automation loop.

• Protocol connection replaces wireless I/O modules: G160 connects directly to the CNC controller via RS232 / Ethernet, establishing a protocol-level channel (FOCAS / SINUMERIK / M70, etc.), fully replacing retrofit wireless I/O. One G160 per CNC — plug-and-play, standardized configuration. 10 CNC = 10 G160, unified management, remotely maintainable; failure points shrink from "N wireless I/O points" to "1 gateway / CNC".
• Read D/M registers → fully sense CNC status: The upper scheduling system reads CNC mode, current process, progress, alarm codes, active program number in real time. The robot no longer "waits blindly" but "acts on status" — whether the door is open, whether it is machining, whether there is an alarm is clear at a glance.
• Write registers / M-codes → precisely control CNC actions: Door open/close, blow, start machining are no longer dependent on fixed I/O triggers, but implemented via M-code writes combined with macros, expressing complex branching and process logic — control dimension upgraded from "on/off" to "protocol-level".
• Program up/down load completes the "last mile": The upper system pushes CNC programs via API; after pushing, it reads back for verification to confirm complete write before starting. Program changes require no downtime, no USB. CNC-side actions are driven by G160 register reads/writes; robot-side actions by the scheduling system; the two align via the G160 protocol channel.
• Full-process automated closed loop: Program push → notify robot to approach target CNC → G160 reads status for safe confirmation, writes M-code to open door → robot loads and exits → write M-code to close door and start machining → machining done, door opens, notify robot to unload → unload then load, next cycle fully unmanned.

VI. Why AIS-G160

The three capabilities "complete protocols + register read/write + program up/download" exactly match all requirements of loading/unloading linkage.

• Complete protocols: AIS-G160 supports 500+ industrial protocols, including native drivers for mainstream CNC brands (FANUC FOCAS, Siemens SINUMERIK, Mitsubishi M70/M80, HEIDENHAIN, GSK, etc.); mainstream CNC controllers are 90%+ supported — no per-brand development.
• M-code register read/write: Supports D/M register read/write to the CNC internal PLC, enabling "register-level" interaction between upper applications / external devices (loading robot) and the CNC — the robot knows what the CNC needs, the CNC knows what the robot did: a bidirectional closed loop.
• Program up/down load: API-encapsulated; upper applications can push CNC programs directly and read back for verification, forming an "acquire — upload — feedback control" data loop with MES / DVS platforms.
• Compliant, flexible deployment: General machining workshops use the workshop management network / 4G; military or classified machining must use private / intranet deployment with 4G not connecting to public networks; multiple workshops/bases connect all G160 to the DVS platform, with robot scheduling via platform API.
