Per ANSI safety standards, your application can only be started from a single “point of control”. The “point of control” is referred to as a “Control Device”.  The program must be started by the "Control Device".  The Control Device is selected from the EPSONRC+5.0|Setup|Controller|Configuration tree item|Control Device listbox.

Here is a brief explanation of each Control Device ->

Control Devices:

PC:  The PC will be permanently connected to the controller.  The operator can start the application from a custom Visual Basic interface (using an optional software package called VBGuide) or from a "pre-canned" HMI called the "Operator Window".

OP:  Start, Stop, Pause, Continue etc....are all handled by a small touch panel operator interface called an OP1.

Remote I/O:  The RC180 was primarily designed to be a slave to a PLC. When the Control Device is Remote I/O, the RC180 is driven by discrete digital I/O or Fieldbus I/O.  "Remote I/O" bits are configured for specific purposes like "Start", "Stop", "SetMotorsOn", "Error" output,  etc...The Remote I/O functionality is controlled by the system (...no programming is required to get this functionality).

Remote Ethernet: "Remote Ethernet" allows you to send Remote commands through Ethernet.  Some of the commands are ->

Execute command, Start, Stop, Pause, Continue,Reset, SetMotorsOn/Off, Home GetIO, SetIO, GetVariable, SetVariable, GetStatus etc…

Remote RS232: "Remote RS232" allows you to send specific protocol commands through RS232 to control and monitor the robot and controller.  Some of the commands are ->

Execute command, Start, Stop, Pause, Continue,Reset, SetMotorsOn/Off, Home GetIO, SetIO, GetVariable, SetVariable, GetStatus etc…

Note:
The RC180 can not automatically start a program on controller power up.
