Introduction

For CJ1W-EIP21 units manufactured after 2012, it is possible to create EIP connections with odd numbers of bytes. However, Sysmac requires you use variables with even numbers as part of the tag creation process for the CJ1W-EIP21. 

To work around this you must create a tag that is one byte larger and then reduce its size to the odd number in the tag creation step.

Example

Global Input variable. Note that the variable is 6 bytes.

Linked tag, note the size is 5 bytes (this must be manually overridden as it defaults to 6 bytes).
