Functions Execution of CPU Unit’s external interrupt
tasks The CPU Unit’s external interrupt tasks (task numbers 0
to 99) can be executed from the Unit using the MCRO
instruction in the Unit’s program.
Constant cycle time A constant cycle time can be set in the range 0.1 to
50 ms (in 0.1-ms units).
Using this function, even if all the necessary processing
is completed in less than the set time, the next cycle will
not start until the constant cycle time setting has elapsed.
(If the constant cycle time is exceeded, the Constant
Cycle Time Exceeded Flag turns ON.)
Cycle time monitoring If the cycle time exceeds 10 ms, the Cycle Time Over
Flag (SR 23509) turns ON, and operation continues.
(This function can be turned OFF in the Unit Setup Area.)
When the cycle time exceeds the cycle monitor time,
operation stops. The cycle monitor time can be set in the
range 1 to 100 ms in 1-ms units (default setting: 50 ms).
Note The cycle time’s maximum value and present value
are stored in the AR Area.
I/O refreshing Cyclic refreshing, immediate refreshing by IORF
CS1W-HCA22 only: Immediate refreshing of analog
output values
Note It is not possible to set immediate refreshing for each
instruction.
I/O memory holding when changing
operating modes Not possible.
Mode setting at power-ON Possible (Specified in the allocated words of the DM
Area.)
MCRO instruction Calling of subroutines and passing arguments and
executing CPU Unit’s external interrupt tasks
Debugging Differential monitoring
Online editing User programs can be overwritten in program-block units
when the CPU Unit is in MONITOR mode. With the
CX-Programmer, more than one program-block can be
edited at the same time.
Note During overwriting using online editing, the Unit can-
not perform operations and the program will be inter-
rupted for 1,200 ms max.
User memory
(UM)
protection Program protection In the Unit Setup Area, it is possible to prohibit writing to
the user program, the general-purpose read-only portion
of DM Area, the Unit Setup Area, and expansion
instruction information from the Programming Device.
