The table below lists the types of system I/O signals.
Fixed by System
| Type | No. of points | Function | |
|---|---|---|---|
| System input | 7 | External Emergency Stop 1, External Emergency Stop 2, Enable Auto 1, Enable Auto 2, Step Stop (All tasks), Protective Stop 1, Protective Stop 2 | |
| System output | RC8A | 18 (Note1) | Auto Mode, Robot Initialized, Robot Running, CPU Normal, Robot Error, Operation Preparation Completed, Battery Warning, Pendant Emergency Stop 1, Pendant Emergency Stop 2, Deadman SW 1 [Enable SW 1], Deadman SW 2 [Enable SW 2], STO Monitor 1a, STO Monitor 2a, STO Monitor 1b, STO Monitor 2b, Continue Start Permission (selectable by I/O parameter) (Note1), Auto Mode 1 (safety output) (Note2), Auto Mode 2 (safety output) (Note2) |
| RC8 | 16 (Note1) | Auto Mode, Robot Initialized, Robot Running, CPU Normal, Robot Error, Operation Preparation Completed, Battery Warning, Pendant Emergency Stop 1, Pendant Emergency Stop 2, Deadman SW 1 [Enable SW 1], Deadman SW 2 [Enable SW 2], Contactor Contact Monitor 1a, Contactor Contact Monitor 2a, Contactor Contact Monitor 1b, Contactor Contact Monitor 2b, Continue Start Permission (selectable by I/O parameter) (Note1) | |
| Input for command execution | 7 | Command (3 bits), data area (3 bits), and Strobe Signal | |
| Output for command execution | 1 | Command Processing Completed | |
Note1 : The terminal number 53 (port number 24) on Mini I/O is assigned to a user output at the factory default.
You can assign this terminal to a system output (Continue Start Permission output signal) by setting the I/O parameter of "23 : User or System output setting" to "1".
Note2 : Except for RC8A Safety I/O-less specification.
Controlled by User Program
| Type | No. of points | Function |
|---|---|---|
| User input | 8 | Inputs to read the external I/O status with an IN command or IO [ ] variable. Used for analysis condition identification, condition satisfaction wait, data input from the external equipment, etc. |
| User output | 7 (Note1) | Outputs to issue a signal to the external equipment during program execution with SET and RESET commands, etc. |
| HAND input | 8 | Inputs to read the external I/O status with an IN command or IO [ ] variable. Used for checking the hand status. |
| HAND output | 8 | Outputs to issue signals to the external equipment with SET and RESET commands, etc. Used for controlling the hand to open or close. |
Note1 : The terminal number 53 (port number 24) on Mini I/O is assigned to a user output at the factory default.
You can assign this terminal to a system output (Continue Start Permission output signal) by setting the I/O parameter of "23 : User or System output setting" to "1".
