TRANSMISSION DATA DESCRIPTIONS

• INPUT-ONLY or OUTPUT-ONLY DATA

Data areas specified with the side DIP switches are assigned

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.

• I/O MIXED DATA

Half of the words specified with the KS0 through KS3 are as-

signed to the inputs, the other half to the outputs.

Module 1 is always assigned to the input. Insert the input

modules to the slots 1 and 2, and the output modules to the

slots 3 through 7.

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 settng is avaliable 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

4

Module 2

Module 3

Module 4

Module 5

Module 6
