UD70
Issue code: 70nu2
1-2 Introduction
UD70 connected to a host computer by a serial link
1.2 Memory
The compiled UD70 program and the user-created source program are
stored in non-volatile EEPROM memory on the UD70 card. This type of
memory allows the programs to be loaded using the serial port.
Latest versions of programs can be easily updated without removing any
integrated circuits or without using any specialized programming equipment.
The filing system of the
UD70 allows only one program to be stored in the
UD70 at any one time.
The compiled program can be stored along with the DPL source code. This
allows the site engineer to read the program stored in the
UD70, even if the
program is not on the host PC. (This option can be disabled if it is not required.)
