我的ＰＬＣ型號是CUP313C-2DP(313-6CF03-0AB0),但不帶MMC卡，裝載不了程序。提示是：
ONLINE:        Block cannot be stored in the load memory or the work memory of the CPU.
    　　　　　Note the restrictions of the CPU being used.

EPROM:        Block or BESY-Update (operating system update) is too large for the remaining memory capacity on the Memory Card/MMC.
請用是否非得要用MMC卡？

應該是需要的

看一下該PLC的說明書,上面會有說明的.
