TRANSMISSION DATA DESCRIPTIONS
The DIP SW located at the side of the module specifies each I/O module's data allocation (occupied data area and size of the
I/O data area).
For example, when the data areas are assigned as shown below:
Module 1
4
Module 2
4
Module 3
4
Module 4
1
Module 5
1
Module 6
1
Module 7
1
I/O data area: 252 words each for input and output.
Then the I/O data are assigned as in the figures below:
■ OUTPUT DATA
The figure below shows the allocation of the data sent from
the network module to the master.

The area enclosed with bold line is assigned for I/O data
Module Status, Error Status and Data Error Status are assigned to the last three words of the output data respectively.
Each module can handle either input or output data.
• Module Status indicates whether individual I/O modules are mounted or not. The bit corresponding to the mounted slot
turns to "1," and the unmounted slot to "0."
• Error Status indicates error status for each module as described below. The bit corresponding to such module turns to "1."
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A:
R3-YSx:
• Data Error Status indicates overrange (R3-US4: out of -10% to +110%; the other types: out of -15% to +115%) status for each
module. The bit corresponding to such module turns to "1."
