Controller address setting
The controller address setting when conducting Polling I/O communication is set by the attribute ID
245 of object instance (instance ID) 1 to 31 in Z-TIO module object (0x64: 64Hex).
Corresponding object: Z-TIO module object (0x64: 64Hex)
Object class ID: 64
Instance ID:
1 to 31
Attribute ID:
245 (Controller address setting)
Write data:
0 to 32 *
* For a Z-TIO module, set the data within the range 1 to 16. For a Z-DIO
module, set the data within the range 17 to 32.
(A combined maximum of 31 modules can be connected, with a maximum of
16 Z-TIO modules and a maximum of 16 Z-DIO modules)
Set “0” in non-connected controllers
Controllers with addresses set to “0” will not perform communication. If a value other than “0”
(1 to 32) is set in a non-connected controller, communication will take place, however, all data
will be “0.”
Action mode selection
The action mode selection when conducting Polling I/O communication is set by the attribute ID 246
of object instance (instance ID) 1 in Z-TIO module object (0x64: 64Hex).
Corresponding object: Z-TIO module object (0x64: 64Hex)
Object class ID: 64
Instance ID:
1
Attribute ID:
246 (Action mode selection)
Write data:
Bit data
Bit 0: Address setting method transfer
0: Continuous setting
1: Free setting
Bit 1: PID/AT transfer by Polling I/O communication
0:

Automatic acquisition of controller address setting
The Automatic acquisition of controller address when conducting Polling I/O communication is set by
the attribute ID 247 of object instance (instance ID) 1 in Z-TIO module object (0x64: 64Hex).
Corresponding object: Z-TIO module object (0x64: 64Hex)
Object class ID: 64
Instance ID:
1
Attribute ID:
247 (Automatic acquisition of controller address)
Write data:
0: Do not execute the automatic acquisition
1: Execute the automatic acquisition *
* Automatically reverts to “0: Do not execute the automatic acquisition”
after automatic acquisition.
When automatic acquisition of controller address is executed, the
“number of communication controllers” and “controller address”
parameters are updated.
The controller address automatic acquisition set “1: Execute the automatic acquisition,”
performs the automatic acquisition of the controller address by turning on the power again.
