FXCPU Structured Programming Manual
(Basic & Applied Instruction)
Cautions
1) About bit device digit specification to be specified by
Specify K1 to K4 in the case of 16-bit operation instruction, or K1 to K8 in the case of 32-bit operation.
2) When handling 32-bit data in structured program, unlike the simple project, you cannot specify the 16-bit
device directly. Use the label when handling 32-bit data.
However, the 32-bit counter is a 32-bit long device, and can be specified directly.
Use the global label when specifying the device.
3) FX PLC supports the instruction in V2.10 or later.
U
4) FX PLC does not support the instruction of pulse operation type.
0N
To execute pulse operation, make the instruction execution condition pulse type.
5) Object devices are limited.
