2.INTERNAL OPERATIONS
112 PROSEC T2N
The programming support functions form part of the functions realised as a result
of peripheral support processing. Details of the programming support functions
are explained in separate manuals for the programmer. The explanation here
relates to an overview of the functions and their relation to the T2N operation
modes.
(1) Memory clear
When the memory clear command is received, the content of the user
program memory (RAM) is initialized and the content of the user data memory
(RAM) is cleared to 0.
(2) I/O automatic allocation
When the I/O automatic allocation command is received, the types of I/O
modules mounted are read and the I/O allocation information is stored on
the system information. (System information is in the user program memory.)
(3) Reading the I/O allocation information
The I/O allocation information is read from the system information, and sent
to the peripherals.
(4) Writing I/O allocation information
I/O allocation information received from peripherals is stored on the
system information.
(5) Reading the system information
The system information (program ID, retentive memory specification,
number of steps used, scan mode specification, other) is read and sent to
the peripherals.
(6) Writing system information
The system information (user set up items) received from the peripherals
is stored in the system information.
(7) Reading the program
In response to a request from peripherals, a specified range of instructions
is read from the user program memory, and sent to the peripherals.
(8) Writing the program
A specified range of instructions is received from peripherals and written
onto the user program memory. After writing, a BCC (check code) correction is
carried out immediately.
(9) On-line program change
