Axis Address R/W Name Description
Common 6100 R/W Writing position data to
the flash memory
Writes position data to the flash memory.
X = 0: No data has been written or data has been
written.
X = 1: Data is being written or data has been written.
Set this area to 1 to write position data to the flash
memory. The area will be set to 0 when the data has
been written.

6101 R/W Writing parameters to
the flash memory
Writes parameters to the flash memory.
There is no difference in usage between parameter
flash memory write and position data flash memory
write.
4-5 Details of I/O Transfer and Necessary Information
I/O transfer makes it possible to transmit or receive data of 6,000 words max. or
2,000 position data items at a time.
A total of 6,000 words is used to transfer 2,000 position data items (i.e., 2,000 x
3).
Use I/O transfer if it is necessary to transfer a large number of data items.
4-5-1 Instructions and Data
The following information is necessary for the transmission and reception of
position data using I/O transfer. Refer to Section 6 PC Data Area Interface for
details.
4-5-2 Common Data for Transmission and Reception
Initial Setting Area I/O transfer uses the expansion data area of the PC data area interface. There-
fore, the following settings are necessary in the initial setting area.
•
To set the expansion data area in the DM area or EM area (available to the
C200HX and C200HG only).
•
To determine the first word of the DM area or EM area to which the expansion
data area is allocated.
Expansion Data Area The expansion data area must contain the following data.
• Data used for transmission:No. of data transfer words
Data source word
Data destination address
• Data used for reception: No. of data transfer words
Data source address
Data destination word
The data items used for transmission or reception can be referred to when the
transmission or reception control bit is turned ON.
