CPU MODULE FUNCTIONS
Transfers data stored on an SD memory card to the program memory or the
standard ROM at power-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 output mode when operation status of the CPU module is changed from
STOP to RUN.
Sets input response time values for modules such as the input module.
Sets whether to clear or hold the output status to each module at the time of a stop
error of 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.
Prohibits writing/reading data to/from each file in the CPU module.
Prevents unauthorized access from external devices using the built-in Ethernet
function or serial communication module.
Changes the CPU module status to RUN or STOP without using switches.
Changes the CPU module status to PAUSE without using switches. Outputs (Y) are
held.
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 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.
Continuously collects data of the specified device at a specified timing.
Writes programs while the CPU module is in the RUN status.
Collectively writes files while the CPU module is in the RUN status.
Enables simultaneous debugging from multiple programming tools.
Self-diagnoses the CPU module to see whether an error exists or not.
Clears continuation errors by error type. User can specify continuation errors to
clear.
Sets the timing to turn off and indication of the LEDs located on the front of the CPU
module.
Lists descriptions of errors occurred in the intelligent function module.
