• Tag Set Name: If the Wizard is used, the names will be automatically
assigned using consecutive IP addresses in the following form for both
input and output tags: TagSet1_192168.250.1. There is no reason to be
concerned with these names. If the Wizard is not used, then names will
not be automatically assigned and they must be entered directly into the
data link table.
• Total Size: The total number of words in areas 1 and 2.
If PLC status is included, the displayed value will be incremented by 1
word (Network Configurator 1.21 or higher). This value is automatically
displayed after the sizes of areas 1 and 2 are entered.
• Node: For an input tag, this is the IP address of the node that provides the
output. For an output tag, "-" will be entered automatically.
• Target Variable: The target tag set name. For an input tag, this is the
name of the target set that provides the output. For an output tag, "-" will
be entered automatically.
• RPI (ms): The requested packet interval for an input tag. For an output
tag, "-" will be entered automatically.
The setting procedure is described here along with setting examples.
