TRANSMISSION DATA DESCRIPTIONS
The DIP SW located at the side of the module specifies each I/O module's data allocation (occupied 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
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.

+18
Module Status, Error Status and Data Error Status are assigned to +16, +17 and +18 respectively.
Each module can handle either input or output data. Input and output cannot be mixed in one module.
Input data from the master device is transferred to the module's output data area. The master device can read from the
output data area the data it has set.
• Module Status indicates whether individual I/O module are mounted or not. The bit corresponding to the mounted slots
turns to "1," and the unmounted slots to "0."
• Error Status indicates error status for each module as described below. The bit corresponding to such modules turns to "1."
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A: Power input in error or disconnected
R3-YSx: Output current error (e.g. load unconnected)
• 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 modules turns to "1."
■ INPUT DATA
The figure below shows the allocation of the data sent from
the master to the network module.
