Wiring between an I/O Extension Board and the Equipment Management Device

To communicate system I/O signals through an I/O extension board, safety signal wiring must be also connected to Mini I/O.

Refer to the figure below.

I/O extension board

For example, DeviceNet slave board, CC-Link remote device board. For details, refer to "Overview of I/O Extension Boards".

  • To use Ethernet and EtherCAT for the method of communicating between robot controllers, install an EtherCAT master board to the master controller.
    When an EtherCAT master board is installed, a parallel I/O board cannot be used (because both an EtherCAT master board and a parallel I/O board are PCI boards).
    I/O extension boards other than parallel I/O boards can be used.
  • When a parallel I/O board is used, system I/O signals can be allocated to Mini I/O. For other wiring methods, refer to "Wiring between Mini I/O and the Equipment Management Device".
Safety signal wiring

For details, refer to "Robot Controller Requirements and Safety Signal Wiring".
System output signal

Some of system output signals output the logical AND or OR of both the master and slave controller states.

For details on system output signals in each allocation mode, refer to the reference in the table below.

Standard Mode Refer to "States of System Output Signals in the Standard Mode".
RC3 Compatible Mode Refer to "States of System Output Signals in the RC3 Compatible Mode".
