TITLE
Addition of Machine Remote Diagnosis
and Unsolicited Message
Unsolicited Message function
1. Overview
This additional manual explains the parameter settings and operations of a CNC side (Fast Ethernet
board/Fast DataServer) about Unsolicited Message function.
In the Unsolicited Message function, the message can be voluntarily notified from CNC to the
personal computer according to the instruction of the ladder program. So, in the PC application, the
state of CNC can be observed without the polling process. Arbitrary data of PMC can be transmitted
as the message. In the PC application, the polling process to inquire the state of CNC regularly
becomes unnecessary by using this function.
As for the programming of the PC application software, please refer to “FANUC Open CNC
FOCAS1/Ethernet CNC/PMC Data window library”.
The application checks
the change in the
CNC/PMC data.
