CJ-series PLCs
• Loop Controller element-to-CPU Unit element:
Run Status Flag, PV Error Input Flag, MV Error Input Flag, Execution Error Flag, Function Block Data-
base (RAM) Error Flag, Automatic Cold Start Execution Flag, Backup during Operation Flag, Function
Block Changed Flag, etc.
• CPU Unit element-to-Loop Controller element:
Start Mode at Power ON: Hot/Cold Start bit.
User link tables are used to allocate function block ITEM data in any part of I/O memory in the CPU Unit.
(CIO, Work, Holding, or DM Areas, or EM Area bank 0)
HMI function used to allocate function block ITEM data for Control, Operation, External Controller, and
System Common blocks in the specified bank of the EM Area in the CPU Unit.
None
Two LED indicators: RUN and ready
All function block data (including sequence tables, step ladder program commands), stored error log data
5 minutes at 25 ° C
Function block data
Automatically transferred when power to CPU Unit is turned ON if startup mode is set for a cold start, or
executed from CX-Process Tool (as required).
0.8 ms max. (depends on function block data contents)
1.06 A for 5 VDC (current consumption for Loop-control CPU Unit including CPU Unit element and Loop
Controller element)
Note: Increased by 150 mA when NT-AL001 Link Adapter is used.
