Number of communication controllers setting
The number of communication controllers when conducting Polling I/O communication is set by the
attribute ID 236 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:
236 (Number of polling I/O communication controllers)
Write data:
1 to 31
Number of communication data items setting
The number of communication data items when conducting Polling I/O communication is set by the
attribute IDs, 240 and 241 of object instance (instance ID) 1 in Z-TIO module object (0x64: 64Hex).
Attribute ID 240: Number of communication measured data items (IN)
Attribute ID 241: Number of communication setting data items (OUT)
Corresponding object: Z-TIO module object (0x64: 64Hex)
Object class ID: 64
Instance ID:
1
Attribute ID:
240 (Number of communication measured words)
241 (Number of communication setting words)
Write data:
0 to 200 words
The number of communication data items can be calculated from the following equation.
Number of communication data items
=
(Number of words of first communication item for one module
1
+
Number of words of next communication item for one module
1

In the case of two-channel type (Z-TIO-B modules), the number of the words per one module is
the same as four-channel type (Z-TIO-A modules).

Measured data items (IN)
Receive counter: 1 word, Alarm state: 2 words, RUN/STOP state: 2 words
Setting data items (OUT)
Setting state selection: 3 words, RUN/STOP transfer: 2 words
