Modify the settings as necessary.



Name (Device name)

You can assign a desired name. The following

tags will be generated based on the entered

names and used for the data sent and received

in the cyclic communication.



(Device name): I

..... Information received from

the IV series



(Device name): O

... Information to be sent to

the IV series



(Device name): C

... Not used.



Comm Format

You can enter a desired format. Due to the

structure of the assembly object, programming

will be easier with a format that supports a

2-byte alignment.



IP Address

You can enter the IP address of the IV series.



Input (Assembly Instance)

Enter “100”.



Input (Size)

You can enter the Input Assembly size of the IV

series.



Output (Assembly Instance)

Enter “101”.



Output (Size)

You can enter the Output Assembly size for the

IV series.



Conguration (Assembly Instance)

Enter “1”.



Set the RPI (communication cycle) for the

cyclic communication.

Make sure to set a value longer than or equal to 5 ms.

5
