Byte 0
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 0:
Echo back of Byte 0 of send data, and data updating state of
controller (Bit 5)
The details of data in Byte 0 sent to the controller from the PLC and data
updating state of controller (Bit 5) are returned.
Byte 0 (Attribute)
Bit 7 Bit 6 Bit 5
Bit 0
Byte 1:
Echo back of Byte 1 of send data
The specified controller device address is returned. However, if there is no
specified device address, “FFH” is returned.
Byte 2, Byte 3: Echo back of Byte 2 and Byte 3 of send data
The communication item address of controller, to/from which data is
written/read is returned. However, if any communication item address out of the
data range or of unused item is specified, “FFFFH” is returned.
Z-TIO module Data address range:
0000H to 035BH
Z-TIO module Address range of memory area: 0500H to 0553H
Z-DIO module Data address range:
0000H to 00DBH
Byte 4, Byte 5: Data of communication item
−
For data read, the current value of relevant communication item is stored.
−
For data write, the current value of relevant communication item is stored.
If the written data is validated, the written value is returned.
If the written data is invalidated, the present (before data write) value is
returned.
When the data is written, there is a delay in rewriting the data in this
register as the COM-JG updates the register after rereading the data on
the controller.

Bit 6: Send data validate/invalidate discriminating bit
0: Send data is validated
1: Send data is invalidated
Bit 7: Read/Write discriminating bit
0: Data read
1: Data write
Bit 5: Data updating state of controller
0: Data update
1: Data non-update
