7.4 Structure Creation Instructions
Ex.
Correct operation: While D0 is specified for FD0 in the subroutine program, D4 is used in the subroutine program.
• Up to 16 CALL(P) instructions can be nested. Note that the 16-level nesting is the total of the CALL(P), FACLL(P),
ECALL(P), EFCALL(P), and XCALL instructions.
• Devices which are turned on in the subroutine program hold the on state even when the subroutine program is not
executed. The on state can be changed to off by executing the FCALL(P) instruction.
Precautions
• An FBD/LD program cannot be created as a subroutine program.
• FBD/LD does not support the execution of a subroutine program with an argument.
Operation error
(1) The operation result of the subroutine program is stored.
(2) These values are replaced with the function device values.
(3) Undefined values are stored.
Error code
(SD0)
Description
2820H
The device specified in an argument from (s1) to (s5) cannot be secured for the data size.
3360H
More than 16 CALL(P) instructions are nested. (The 17th instruction is executed.)
3380H
The subroutine program corresponding to the pointer specified by (P) does not exist.
3381H
After execution of the CALL(P) instruction, the END, FEND, GOEND, or STOP instruction is executed before the RET instruction.
3382H
The RET instruction is executed before the CALL(P) instruction.
