Online Functions

Connect the computer in which GX Works3 has been installed and the CPU module, and read or write data from/to the flexible
high-speed I/O control module through the CPU module. The following table lists the online functions.

*1 The states of I/O signals in the hardware logic are described as High and Low. For details, refer to the following.
Page 116 Signal status name
If a communication error occurs while an online function is being executed, the possible cause is one of the
following causes. Check the target module and communication status.
• A module with the target start I/O number does not exist.
• A communication error has occurred during online access.
• Cable error
Start I/O number setting
Set the start I/O number of the flexible high-speed I/O control module.
[Online]  [Start I/O number setting]
Setting the I/O assignment to GX Works3 and the configuration tool enables writing of data into the flexible high-speed I/O
control module and the monitor display through the CPU module.
However, match the I/O assignment of the flexible high-speed I/O control module in the configuration tool and that in GX
Works3. If the I/O assignment is changed on GX Works3 and data writing to the module, the monitor display, or simulation is
executed after the start I/O number has been set with the configuration tool, a communication error will occur.
2 FUNCTIONS OF THE CONFIGURATION TOOL

2.8 Online Functions
Description
Sets the start I/O number of the flexible high-speed I/O control module.
Writes the hardware logic to only the execution memory.
Writes the hardware logic to both the execution memory and the flash ROM.
Reads the hardware logic saved in the flash ROM to the configuration tool.
Verifies the hardware logic in the configuration tool and the setting data written
in the flash ROM.
Starts/stops the hardware logic control.
Monitors the ON/OFF states of I/O terminals and count values.
The following lists the items that can be monitored.
• ON/OFF states of external input terminals corresponding to external input
blocks (hardware logic outline window)
• High/Low states of output terminals in an external input block (hardware logic
outline window)
• High/Low states of the Output 0 terminal in a multi function counter block
(hardware logic outline window)
• High/Low states of input terminals in an external output block (hardware logic
outline window)
• ON/OFF states of external output terminals corresponding to external output
blocks (hardware logic outline window)
• Internal action states of input terminals and count values in a counter timer
block (multi function counter block detail window)
