Using CP 【nciRcvHrtBt_1】 【nciRcbHrtBt_2】
Control unit LM ADAPTER
Relating CP Nothing
Data holding Memorizing set values in nonvolatile memory.
Reference NV Objective variable lastly updated
This is to be used to determine the operation when the periodical updating to LM ADAPTER is eliminated such
Purpose as in the case when the master system is downed or communication error
