7 APPLICATION INSTRUCTIONS
7.4 Structure Creation Instructions
• When the execution command is turned off, non-execution processing of the subroutine program is performed, enabling the
OUT instruction and PLS instruction (including pulse conversion instructions) to be forcibly turned off.
Ex.
When the FCALL(P) instruction is used
When the FCALL(P) instruction is not used
• When the subroutine program uses function devices (FX, FY, FD), specify the devices corresponding to the function
devices in (s1) to (s5). The following figure the contents of the devices specified by (s1) to (s5).
(1) Forced off by the FCALL instruction
• Before execution of the subroutine program, bit data is transferred to FX and word data is transferred to FD.
• After execution of the subroutine program, the contents of FY and FD are transferred to the corresponding devices.
• Function devices FX and FY are processed in units of bits. Function device FD is processed in units of 4 words. The size of data to be processed varies
depending on the type of the device specified by an argument. The device specified as a function device should be secured for the data size. An error occurs
if it cannot be secured for the data size.
