Note 1. The H, W, D, and E characters can also be input in lower case as h, w, d, and e.
2. Be sure to directly enter the CPU Unit's I/O memory address (e.g., 100, W100, D0) or a network vari-
able as a character string.
6 Input the size of the tag in the Size Field, in bytes. The input size should match the actual size
(refer to section 9-5-4 Determine Tag Sizes on page 9-40 for more information).
7 Click the Regist button to register the tag.
If an I/O memory address is specified for a tag name, the Edit Tags Dialog Box will be displayed
with the next consecutive address as the tag name for editing the next tag. Once you have reg-
istered the tags, click the Cancel button.
8 Click the Out - Produce Tab, and then click the New button. The Edit Tag Dialog Box is dis-
played. Input the output tag in the same way. Use the Fault Action setting of the output (pro-
duce) tag to specify whether to clear the output data or continue to send it when a major fault
occurs in the CPU Unit. The Fault Action setting is not required for input (consume) tag sets.
• Retain output for major fault: Hold (default) - Output data maintains its previous status even
after a major fault occurs.
• Clear output at major fault: Clear - Output data is cleared to 0 when a major fault occurs.
Note When any of the following errors occurs in the originator PLC while tag data links are in progress, the
connection will be forcibly disconnected.
• Fatal CPU Unit error
• I/O refreshing error
• CPU Unit WDT error
• I/O bus error
