Applicable devices
*1 Devices other than F can be used.
• In safety programs executed by the Safety CPU, only the following safety devices and constants can be used.
Processing details
• When the FCALL (P) instruction is executed, this instruction executes non-execution processing
*2
of the subroutine
program of the pointer (P). The FCALL(P) instruction can disable the execution of the subroutine program specified by a
pointer in the same program file or the subroutine program specified by a global pointer.
*2 Non-execution processing is the same as the processing performed by each coil instruction with the condition contact set to off.
• The operation results of individual coil instructions after the end of non-execution processing are as follows regardless of
on/off of the condition contact.
• The FCALL(P) instruction is used in combination with the CALL(P) instruction. If the FCALL(P) instruction is not used in
combination with the CALL(P) instruction, non-execution processing of the subroutine program is not performed even if the
execution command is turned off, and therefore the output status of each coil instruction is retained.

(1) Non-execution processing is performed when the command of the
FCALL(P) instruction changes from on to off.
Device used for operation Operation result (device status)
High-speed timer, low-speed timer Set to 0
High-speed retentive timer, low-speed retentive timer, counter Maintains the current status.
Device in OUT instruction Forcibly turned off.
Device in the SET, RST, SFT(P), or basic/application instruction Maintains the current status.
PLS or pulse instruction (  P) Performs the same processing as when the condition contact
is off.
