Password registration
This function provides read/write protection for files
stored in the CPU module against access from the GX
Developer.
Section
6.19.1
Remote password
A function to prevent illegal access from external
sources with serial communication modules and
Ethernet modules.
Section
6.19.2
System display
This function connects to the GX Developer and
monitors system configuration.
Section
6.20
LED display
This function enables the front-mounted LEDs to
indicate the operating conditions of the CPU module.
Section
6.21
Section
6.22.1
Preference setting
This function sets failure preferences to turn off LED
displays.
Section
6.21.2
High speed interrupt function
This function executes an interrupt program by fixed
scan interrupt at 0.2ms to 1.0ms intervals using the
interrupt pointer I49.
Section
6.22
Interrupt from intelligent function
module
This function executes an interrupt program at the time
of interrupt request from the intelligent function module.
Section
6.23
Serial communication function
This function connects the RS-232 interface of the
Q00CPU or Q01CPU and the personal computer/
display device or like with the RS-232 cable and makes
the communication by MC protocol.
Section
6.24
Module service interval time read
This function monitors the access interval time (time
between the access acceptance of the CPU module and
the next access acceptance) of the intelligent function
module, network module or peripheral device.
Section
6.25
Device initial value
This function registers the data used by a program to
devices or intelligent function module buffer memory
without use of any program.
Section
6.26
Online module change
This function replaces the Q series I/O module, the
intelligent function module of function version C, or the I/
O module or intelligent function module mounted on a
MELSECNET/H remote I/O station online.
In a redundant power supply system, the power supply
module can also be changed online.
*1
Auto tuning function
This function is used to initialize the PID constants.
Auto tuning can be used in a relatively slow response
system that performs the temperature adjustment by
S.PID or S.2PID instruction or similar operation.
