•(For 32 bits)

Monitor and write only b8 to b15 and b24 to 31 of the buffer memory.

Example:

The monitor value is 00870043H when monitoring BM0=87654321H as mask type 6.

(5)Setting of the module No. (MELSEC-FX)

Set the module No. of the special function unit or special function block to monitor or write.

The module No.0 to No.7 are assigned in order for the nearest module or block from the main unit. For details of the module No., refer to the following.

User's Manual (Hardware) of MELSEC-FX

(a)Direct specification

Specify the module No. (No.0 to No.7) of the special function unit or special function block directly, to monitor or write when setting the devices.

(b)Indirect specification*1

Specify the module No. of the special function unit or special function block indirectly, to monitor or write when setting the devices, by using the 16-bit GOT internal data register (GD10 to GD25). When specifying the station No. from 100 to 115 on GT Designer3, the value of GD10 to GD25 corresponding to the module No. will be the module No. of the special function unit or special function block.
