Program Transfer Section 10-1
10-1 Program Transfer
The CX-Programmer is used to transfer the programs, PLC Setup, I/O mem-
ory data, and I/O comments to the CPU Unit with the CPU Unit in PROGRAM
mode. The following procedure is used.
1,2,3... 1. Select PLC - Transfer - To PLC. The Download Options Dialog Box will be
displayed.
2. Specify the items to transfer.
3. Click the OK Button.
Note The program data on a Memory Cassette can be automatic transferred when
the power is turned ON.
10-2 Trial Operation and Debugging
10-2-1 Forced Set/Reset
The CX-Programmer can force-set (ON) or reset (OFF) specified bits in the
CIO Area, Auxiliary Area, and HR Area, as well as timer/counter Completion
Flags. Forced status will take priority over status output from the program or
I/O refreshing. This status cannot be overwritten by instructions, and will be
stored regardless of the status of the program or external inputs until it is
cleared from the CX-Programmer.
Force-set/reset operations are used to force input and output during a trial
operation or to force certain conditions during debugging.
Force-set/reset operations can be executed in either MONITOR or PRO-
GRAM modes, but not in RUN mode.
Note Turn ON the Forced Status Hold Bit (A500.13) and the IOM Hold Bit (A500.12)
at the same time to retain the status of bits that have been force-set or reset
when switching the operating mode.
Turn ON the Forced Status Hold Bit (A500.13) and the IOM Hold Bit
(A500.12), and set the Forced Status Hold Bit at Startup parameter in the PLC
Setup to retain the status of the Forced Status Hold Bit hold to retain the sta-
tus of bits that have been force-set or reset when turning OFF the power.
The following areas can be force-set and reset: CIO Area (I/O bits, data link
bits, CPU Bus Unit bits, Special I/O Unit bits, and work bits), Work Area, Timer
Completion Flags, HR Area, Counter Completion Flags.
