Communication parameter setting by Explicit message communication
Communication item setting, Setting the number of communication controllers, Controller address
setting, Action mode selection and Automatic acquisition of controller address necessary when
conducting Plling I/O communication are described by referring to the same settings made via Explicit
message communication.
Communication item setting
Each communication data item when conducting Polling I/O communication is set by object instance
(instance ID) 1 in Controller communication item setting object (0xC7: C7Hex).

Select the measured data item and
setting data item from among
Z-TIO module object (0x64: 64
Hex), Z-TIO module extended
object (0x65: 65Hex) *, or Z-DIO
module object (0x66: 66Hex) *,
and set the corresponding attribute
ID.
Attribute ID: 1 to 255
0
* When setting the communication items of a Z-TIO module extended object (0x65: 65Hex) or
Z-DIO module object (0x66: 66Hex), set the attribute ID number with the appropriate offset
value (1000 or 2000) added.

Set measured data items in order starting from “Measured data item (IN) 1.” If any of the
following values is set, all items from that item to “Measured data item (IN) 32” are the
same as those when set at “0.”
•
If at “0”
•
If set to attribute ID to which no communication data items are assigned
•
If at 231 to 236 or 238 to 243 as attribute ID
Set the setting data items in order starting from “Setting data item (OUT) 1.” If any of the
following values is set, all items from that item to “Setting data item (OUT) 32” are the same
as those when set at “0.”
•
If at “0”

•
If at 33 as attribute ID (when “Bit 1: PID/AT transfer by polling I/O communication” of
attribute ID “246” (Action mode selection) is “0: Invalidate”)
