Execution Times
Operations of “ ” and “V”
Use “ ” to express transfer to a state relay in an upper position (repeat), transfer to a state relay in a lower position
(jump), or transfer to a state relay in another separate flow.
Use “V” to express reset of a state relay.
1) Transfer source program
2) Transfer destination program
In GX Developer, “z” is automatically displayed in the transfer destination state relay.
3) Reset circuit program
In the program example shown below, S65 is reset from S65 by way of X007.
Reset of another state relay (S70, for example) from S65 is executed in the same way, but in this case S65 is not
reset because this is not transfer.
In GX Developer, “z” is automatically displayed in a state relay to be reset.
