CPU MODULE FUNCTIONS
Boots data stored in an SD memory card to the program memory or the standard ROM
when the CPU module is powered off and on or reset.
Executes a program at a set interval regardless of its scan time.
Monitors operational delays caused by hardware failure or program error of the CPU
module.
Holds the device data of the CPU module.
Registers data used in programs without programs.
Specifies the service processing count or time to be executed in END processing.
Sets the status of the outputs(Y) when the operation status of the CPU module is
changed from STOP to RUN.
Sets input response time for modules such as an input module.
Sets whether to clear or hold the output status to each module when a stop error occurs
in the CPU module.
Sets a operation mode of the CPU module when a hardware error (CPU module
detects SP.UNIT DOWN) occurred in an intelligent function module.
Protects data in the CPU module against tampering and theft by unauthorized persons.
Prohibits writing/reading data to/from each file in the CPU module using a programming
tool. Sets write password and read password for each file stored in the CPU module.
Prevents unauthorized access from external devices.
Prevents access to program contents by setting a block password for each POU.
Changes the CPU module status to RUN or STOP without using switches.
Changes the CPU module status to PAUSE without using switches, holding the status
of outputs (Y).
Resets the CPU module when it is in the STOP status, without using switches.
Clears latch data of the CPU module when the module is in the STOP status, without
using switches.
Measures the execution time of the specified steps in a program.
Displays the scan time and execution status of the program being executed.
Displays the number of executions of an interrupt programs.
Monitors the CPU module under specified conditions.
Monitors and/or tests the local devices of the specified program.
Forcibly turns on/off the external input/output of the CPU module.
Changes a device value for the specified step of a program.
