Communication Software PLC and Ladder Diagram Editing Software
The communication software GSKComm and PLC ladder diagram editing software GSKLadder of GSK988T
are all run in WINDDOWS98 /2000/XP. User can edit part program on PC, upload and download files
of part program, parameter, tool compensation and thread compensation, etc between PC and CNC,
as well as DNC real-time processing. The machine manufacturer can edit the ladder diagram on
GSKLadder of PC, upload and download PLC program between PC and CNC also.
 Remote Monitor Software: GSKMonitor
GSKMonitor runs under WIN98/2000/XP, and remote helps and monitors GSK988T through LAN interface.
 Servo State Diagnosis And Monitor
Through GSKLink, GSK988T realizes diagnosis and monitor of servo state(command position,
feeding position, motor speed and motor current, etc.)
