User memory
To store user programs that are input through the programmer. The user memory of a PLC is usually expressed in word (16 bits/word) as a unit of storage capacity. At the same time, because of the previous system procedures directly related to the performance of PLC, can not be directly accessed by the user. Therefore, usually the storage type or storage mode and capacity referred to in PLC product data are for user program memory.
Common user storage modes and capacity types or storage modes are CM0SRAM, EPR0M and EEPR0M. Information storage is commonly used on cassette tape and disk.
CM0SRAM memory is a kind of medium high density, low function, inexpensive semiconductor memory, can use lithium battery as backup power supply. once the ac power outage, to maintain the lithium battery power supply, can save RAM within the data before the power outage. lithium battery life is usually 1-5 years or so.
EPR0M memory is a kind of constant read-only memory. It is heightened when setting and irradiated by ultraviolet light when erasing. PLC by writer RAM the user program can be solidified into EPR0M of R0M box. Insert R0M box in PLC machine, PLC will execute the user program in R0M box; On the other hand, do not plug in R0M box, PLC execute RAM area user program.
