2.2 MELSEC-L
The device ranges that can be set when selecting
[MELSEC-L] as the controller type are as follows.
*1 Do not set a file register by GT Designer3 when executing
multiple programs with the file of the file register set at [Use
the same file name as the program] by the PLC parameter of
GX Developer.
Otherwise, read/write at GOT will be erroneous.
*2 Available for file register of block No. switched with the RSET
instruction.
*3 Available for file register of block No. of file name switched
with the QDRSET instruction.
*4 GOT treats them in units of 32k (32768 points).
*5 Only the intelligent function module on the station connected
to GOT can be specified.
Set within the address range of the buffer memory existing in
the target intelligent function module.
*6 Do not use local devices set in the MELSEC-L system.
Otherwise, normal monitoring is not performed. (The data
register (D) can be used for D32768 or later.)
*7 This is not supported by GT10.
*8 This cannot be monitored when in GOT multi-drop
connection.
*9 The device No. must be set in multiples of 16.
