4) Write Start Position
5) Write Data Length
• The write data length is specified in bytes.
• The file size depends on the type and number of the function blocks used.
• The most significant bit (bit 15) turns ON when the last data item is writ-
ten.
• Write data length:
The data lengths that can be specified are different for the first packet and
the second or later packets.
- First packet: 90 bytes (See note 1.) ≤ Write data length ≤ 900 bytes (See
note 2.)
- Second packet: 0 bytes ≤ Write data length ≤ 900 bytes (See note 2.)
Note (1) Set the first packet to at least 90 bytes including the header data (90
bytes).
(2) The maximum write data length depends on the network it will pass
through. For Ethernet networks and he peripheral bus, the maximum is
900 bytes, and for SYSWAY, the maximum is 516 bytes.
6) File Data (Write Data)
The data on the backup file (BACKUPE1.PRM) created with the simple
backup function is divided by write data lengths and written to the Loop Con-
troller.
7) Directory Length
• Not used if the command is sent to a Loop Controller. (Set to 0.)
