<p>PURPOSE:To make a sequence program into a ROM with simple constitution by connecting both an activation switch in such modes as writing, reading, collation and erasure recognition and a ROM writer having first half and latter half ROM sockets to a sequence card. CONSTITUTION:The sequence program is generated through the use of a sequence generator 8, and transferred to a RAM on the sequence card 3. A cable 7 is removed out of the sequence generator 8, and connected to the ROM writer 19. The previously erased ROm is mounted on the first half ROM socket 20 and the latter half ROM socket 21, and the mode is selected among writing, collation, reading and erasure recognition modes through a mode switch 22. Then the ROM executing an instruction through a first half/latter half changeover switch 23 is selected to execute the selected mode. During processing, an LED 26 lights up in operation, while in the write mode an LED 25 lights up during writing. At abnormalities an abnormality LED 27 lights up. As a result the constitution can be simplified, and therefore work can be made efficiently.</p> |
