Description
Prohibits writing/reading data to/from each file in the
CPU module using GX Developer.
Prevents illegal access from external sources with
serial communication modules and Ethernet
modules.
Monitors the system configuration using GX
Developer.
Displays the CPU module operation status using
LEDs located on the front of the module.
Sets the priority for error messages stored in SD220
to 227 (LED display data) at the time of error
occurrence. LED can be set to non-display.
Executes an interrupt program by fixed scan interrupt
at 0.2ms to 1.0ms intervals using the interrupt pointer
I49.
Executes an interrupt program at the time of interrupt
request from the intelligent function module.
Connects the RS-232 interface of the Q00CPU or
Q01CPU and the personal computer/display device
with the RS-232 cable, and performs data
communication using the MC protocol.
Monitors the service interval time (time from service
acceptance to next service acceptance) of intelligent
function modules, network modules or GX Developer.
Specifies the service processing count or time to be
executed in END processing.
Registers data required for operations in a program
to devices or buffer memory of intelligent function
modules/special function modules (without using
programs).
Prolongs a battery life by holding only clock data in
the battery.
Checks whether the data in memories of the CPU
module are not modified due to excessive electric
noise.
Backs up latch data such as device data and error
history without using a battery.
Writes/reads device data to/from standard ROM.
