TRANSMISSION DATA DESCRIPTIONS

■ OUTPUT DATA

The figure below shows the allocation of the data sent from

the network module to the master.

■ INPUT DATA

The figure below shows the allocation of the data sent from

the master to the network module.

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:

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 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 (T/C or RTD input): Input burnout

R3-DA16A: Power input in error or disconnected

R3-YSx: Output current error (e.g. load unconnected)

R3-PC16A: External power supply in error or disconnected

• 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.”
