Processing details
• The XCALL instruction controls the execution and non-execution processing of subroutine programs.
• The following table lists the operation result of each coil instruction after the non-execution processing. Regardless of the
status of the condition contact, the following result is applied.
• The following shows the operation of the XCALL instruction.

• In the execution of subroutine programs, each coil instruction is operated according to the ON/OFF status of the condition contact.
• In the non-execution processing of subroutine programs, each coil instruction is operated with the OFF status of the condition contact applied.
Device used for operation Operation result (device status)
1 ms timer, 10 ms timer, 100 ms timer 0
1 ms retentive timer, 10 ms retentive timer, 100 ms retentive timer, counter The current status is held.
Device in the OUT instruction Forcibly turned off.
Device in the SET, RST, or SFT(P) instruction or basic/applied instruction The current status is held.

(1) Rising edge of X0 (OFF  ON): The subroutine program of P1 is executed.
(2) While X0 is on: The subroutine program of P1 is executed. (The rising edge of X0 is not included.)
(3) Falling edge of X0 (ON  OFF): The non-execution processing of the subroutine program of P1 is executed.
