ERROR CODE E1080 Not RPS mode.
Main causes include:
1. External program reset signal is received, but RPS ON signal, or external program
input signal is not dedicated.
2. JUMP is taught in a block step program, but external program input signal is not
dedicated.
3. END is taught in a block step program, but the RPS ON signal is not dedicated.
4. EXTCALL is executed, but the signal for external program input is not dedicated.
Correct the program data.
If RPS is to be used the necessary signals must be dedicated.
