22.4 Backing up Module Data (Writing Data to the Flash ROM)

Precautions
• While the module extension parameters are being written by using the PFWRT instruction, do not power off the system or
reset the CPU module. If the power is turned off or the CPU module is reset while the module extension parameters are
being written, data is not normally written and normal positioning start is disabled. If normal positioning start is disabled,
restart the system as follows.
• Data write to the flash ROM of the positioning module can repeat a maximum of one hundred thousand times. Any attempt
to write data to the flash memory beyond this count results in failure.
• After the power is turned on or the CPU module is reset once, data write can repeat a maximum of 25 times if the program
is used. Any attempt to write data to the flash ROM memory beyond 25 times results in a flash ROM write count error at
error code 1080H, resulting in failure in data write. If one try of write results in a flash ROM write count error, check and
modify the write program. If a flash ROM write count error occurred, reset the error of the positioning module using "[Cd.5]
Axis error reset," or turn on the power or reset the CPU module again.
• The PFWRT instruction is executed when the RD75 READY signal [X0] is off. While the RD75 READY signal [X0] is on, the
instruction cannot be executed. Before executing the instruction, turn off both the PLC READY signal [Y0] and the RD75
READY signal [X0].
Operation error
Method
Description
Restart using the engineering tool
Write the positioning and block start data to the positioning module from the "Write to programmable controller"
of the engineering tool.
Restart using the program
After initializing parameters by using the PINIT instruction, set the module extension parameters in the buffer
memory of the positioning module. Thereafter, execute the PFWRT instruction.
