Slave Module Address Setting
Setting a start number of the address assigned for data communication is required for slave modules.
An address can be written to a slave module or the address assigned to a slave module can be read through infrared
communications using an address writer (manufactured by Anywire Corporation).
For details, refer to the manual of the address writer.

Address setting example
When 0 is set for the 2-point input slave module address, and 0 and 2 for the 2-point output slave module address, bits are
occupied as follows.
■
Buffer memory address of the input slave module
• Areas occupied by address 0: Un\G0.0, Un\G0.1
■
Buffer memory address of the output slave module
• Areas occupied by address 0: Un\G4096.0, Un\G4096.1
• Areas occupied by address 2: Un\G4096.2, Un\G4096.3
Precautions
• A slave module address is not deleted even when the power supply of a programmable controller or a 24 V DC external
power supply is turned off. The address is retained until a new address is set when a system is configured.
• In the address setting, ensure that the address occupied by the slave module does not exceed the number of transmission
points set in the FX5-ASL-M. For the operation mode setting of the FX5-ASL-M, refer to the following.
• In the slave module, a value between 0 and 254 can be written. (This value is not an ID.) Note that 255 cannot be set.
Doing so will cause a No ID setting error.
