System Information
System information is the area which stores execution control
parameters and user program management information when executing
a user program, and occupies 0.5K of the user program memory. The
following details are included in system information.
(1) Program ID
This is the user program identification. A setting of up to 10
alphanumeric characters can be set. The program ID can be
registered/monitored on the system information screen of the
programmer.
(2) System Comments
These are comments attached to the user program. A setting of
up to 30 alphanumeric characters can be set. The system
comments can be registered/monitored on the system information
screen of the programmer.
(3) Memory Capacity
This stores the memory type (user program capacity/data register
capacity). Since the system side will be automatically registered,
registration by the user is not required. The memory capacity can
be monitored on the system information screen of the programmer.
(4) Steps Used
This stores the number of steps used in the user program. Since
the system side performs automatic up-dating every time a user
program is written, registration by the user is not required. The
number of steps used can be monitored on the system information
screen of the programmer.
(5) PLC Type
This stores the model type. Since the system side performs
automatic registration, registration by the user is not required.
The PLC type can be monitored on the system information
screen of the programmer.
(6) Program Size Setting
The T2N is fixed at 24K steps. The program capacity can be
registered/monitored on the system information screen of the
programmer. (no need to set for T2N)
(7) Sampling Buffer Setting
This performs the setting and registration of the storage capacity
of the sampling data from the sampling trace function. In the T2N,
it is fixed at 8K words. The sampling buffer capacity can be
monitored on the system information screen of the programmer.
(Setting is not needed in the T2N.)
