result in unexpected operation.
shown in the ITEM list in the Function Block Reference Manual (Cat. No.
W407) to the receive area (CPU Unit to Loop Controller) in the EM Area. Writ-
ing an out-of-range value can result in unexpected operation by the controlled
machine or equipment.
changed when the PV (process value) is changed in the control block. There-
fore, before executing this function, make sure that the equipment will be safe
even if the MV changes by setting pseudo-inputs. Otherwise, unexpected
equipment operation may result, causing a serious accident.
• Normal operation will be possible only if the CS1D-CPU@@P Process-
control CPU Unit is used in the combination in which it was shipped. Nor-
mal operation may not be possible if the CS1D-CPU@@P Process-control
CPU Unit is used in any other combination. Therefore, do not remove the
Loop Controller component from the CPU Unit. Always replace the entire
CS1D Process-control CPU Unit as one Unit even if only the Loop Con-
troller or CPU Unit has failed.
• The CS1D CPU Unit's cycle time and the Loop Controller component's
LCB load rate are different in duplex mode and simplex mode. Verify the
system's operation in both modes in trial operation before actually running
the system.
• When replacing a CS1D Process-control CPU Unit while power is sup-
plied to the PLC, always switch the DPL Unit's CPU USE/NO USE switch
to "NO USE." Removing the CS1D Process-control CPU Unit with the
switch set to "USE" (power supplied) may damage the CPU Duplex Back-
plane, CS1D CPU Unit, DPL Unit, and Loop Controller component of the
Process-control CPU Unit.
Do not use a CS1W-LCB01 or CS1W-LCB05 Loop Control Board in any CPU
Unit other than the CS1-H.
• If a CS1W-LCB01 or CS1W-LCB05 Loop Control Board is used in a CS1
CPU Unit, a non-fatal INNER Board error will occur and the Loop Control
Board will not operate. (The CPU Unit itself will be able to operate.)
• If a CS1W-LCB01 or CS1W-LCB05 Loop Control Board is used in a
CS1D CPU Unit, a fatal INNER Board error will occur. (In this case, nei-
ther the Loop Control Board nor the CPU Unit will operate.)
• Loop Control Boards before version 1.5 cannot be used with CS1D-
CPU@@S CS1D CPU Units for Single-CPU Systems.
• Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the
CPU Unit to any external device except the CJ1W-CIF11 RS-422A
Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing so may damage
the external device or Loop Control Board.
