*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.
