REMOTE CONTROL INTERFACES
The K-DUCER unit supports the following remote control interfaces to suit your
automation and industry 4.0 needs:
• Remote control via 24V I/O signals (CN3)
• MODBUS TCP via ethernet port (CN5)
• Open Protocol via ethernet port (CN5)
• Interface with K-Expand software via mini-USB or ethernet port
Additionally, a printout of each screwdriving result can be accessed as follows:
• Through serial ports CN4 and CN2, for printing with Kolver printer accessory or
receival with any serial terminal, automatically transmitted at the end of each
rundown
• On a text file saved to a thumb drive connected to the USB type A port (the larger
USB port), automatically generated and saved at the end of each rundown
24V I/O
Introduction
The 24V signals allow start/stop control of the screwdriver, program selection, sequence
selection, error detection and clearing, and more.
The advantage of this system is the simplicity of the control, but its disadvantages are:
• Data acquisition capability is limited to OK / NOK signals and end program / end
sequence signals. Torque and angle values cannot be read via these I/O signals.
• The 24V signals are susceptible to being disturbed by electromagnetic interference
(EMI), especially in the highly noisy electrical environments often found in assembly
lines. Kolver recommends using shielded wires with grounded shields and ferrite
beads to limit EMI.
For these reasons, Kolver recommends using the more robust ethernet port with MODBUS
TCP or Open Protocol whenever possible.
The I/O controls available via CN3 are:
• [I] Actuate the screwdriver motor (START)
• [I] Lock/disable the screwdriver (STOP / PIECE)
• [I] Program selection
• [I] Sequence selection
• [I] Error clearing (ESC)
• [I] Screw, program, or sequence reset (RST)
• [I] End Program / End Sequence acknowledgement (OK)
• [I] Angle counting start
• [O] OK/NOK result
• [O] READY status
• [O] End Program / End Sequence status
• [O] Screwdriver motor status
