OMRON
Function Restrictions when Using CX-Programmer Version 3.3 for the CJ1M-
CPU11/21
Restriction
Program capacity: 5 Ksteps max.
Subroutine numbers for subroutine
instructions (SBS, GSBS, and
MCRO): 0 to 255 only
Jump numbers for jump
instructions (JMP, CJP, and
CJPN): 0 to 255 only
Use only 1 scheduled interrupt.
Use only 1 PWM output.
Note: The Stop CPU on Instruction Error Option in the PLC Setup can be selected to stop program
execution by creating a fatal error when an instruction error is detected. Instruction errors include
instruction processing errors (the ER Flag will turn ON), DM/EM indirect addressing BCD errors, and
illegal access errors. This option can be used to check to see if instruction errors are occurring in
unexpected places in the program.
Although the program capacity of the CJ1M-CPU12/22 is 10 Ksteps, the program
capacity of the CJ1M-CPU11/21 is 5 Ksteps. A program containing more than
5 Ksteps can be written offline, but an error will occur when it is transferred. An error
will also occur if a program transferred automatically when power is turned ON is
larger than 5 Ksteps.
Although the subroutine numbers for the CJ1M-CPU12/22 are 0 to 1023, the
subroutine numbers for the CJ1M-CPU11/21 are 0 to 255. A program containing
subroutine numbers higher than 255 can be written and can be transferred, but an
error will occur when the program is executed.
Although the jump numbers for the CJ1M-CPU12/22 are 0 to 1023, the jump numbers
for the CJ1M-CPU11/21 are 0 to 255. A program containing jump numbers higher
than 255 can be written and can be transferred, but an error will occur when the
program is executed.
Although the CJ1M-CPU12/22 support 2 scheduled interrupts, the CJ1M-CPU11/21
support only 1. Thus, only scheduled interrupt 0 can be used with the interrupt
instructions (MSKR, CLI, and MSKR). A program containing schedule interrupt 1 can
be written and can be transferred, but an error will occur when the program is
executed.
Although the CJ1M-CPU12/22 support 2 PWM outputs, the CJ1M-CPU11/21 support
only 1. Thus, only PWM output 0 can be used with the PWM instruction. A program
containing PWM output 1 can be written and can be transferred, but an error will occur
when the program is executed.
