Transferring Data with CX-Position Section 5-7
Operating Memory Area
When the SAVE DATA Bit (word n+1, bit 14) is turned from OFF to ON, all
parameters and data are saved to flash memory.
5-6-3 Timing Chart for Saving Data
Data cannot be saved and transferred at the same time. Attempting to do so
will result in a multiple start error (error code 8000). It is also not possible to
save data while pulses are being output. The following diagram is a timing
chart for saving data.
When the data saving operation has been completed, the Data Transferring
Bit (word n+8, bit14) is turned from ON to OFF.
5-7 Transferring Data with CX-Position
It is possible to use the CX-Position Support Software to read, write and save
data, and to monitor the operating status of the PCU.
Outline CX-Position is software that can be used for setting all kinds of data used by a
PCU as well as for monitoring the operating status of the PCU.
Creating and Transferring
Data Refer to the CX-Position Operation Manual (W433) for details on its operation.
While CX-Position is used to download data, or to save data to flash memory,
the Data Transferring Flag will be ON.
Note Do not carry out transfer operations from more than one CX-Position for the
same PCU at the same time. There is a probability of the data transfer not
being completed successfully, and of abnormal operation resulting.
