TRANSMISSION DATA DESCRIPTIONS
The DIP switches on the front of the module specify each I/O module's I/O points and I/O type. The DIP switches on the side
of the module specify status data.
The allocation area, which is set in order from the slot No. 1, is assigned to the I/O data. I/O module's data exceeding the
configured area is unable.
With input status data ON, the last 2 words of the input data area are used as status data. The status data setting is available
for firmware version 1.02 or later. For other versions SW3-3 setting is ignored and the device works as if SW3-3 is off. When
I/O data and the status area are duplicated, status data takes priority.
For example, when the total number of I/O points is of 16, the data areas are assigned as shown below:
Module 1
Module 2
Module 3
Module 4
Module 5
Module 6
Module 7
Then the I/O data are assigned as in the figures below:
■ WITHOUT STATUS DATA (SW3-3: OFF)
• INPUT-ONLY or OUTPUT-ONLY DATA
Data areas specified with the side DIP switches are as-
signed to each module from Module 1 through Module 7 in
turn.
If the total number of I/O points is of 4 or 8, non-existing
data are not sent/received.
