Message Recommended Action
Tag: - Explicit Server Output Elements must be 0-63. Reduce the word offset for the associated Tag Address.
Tag: - Data Type implies Packet Bytes should be equal to 2.
Certain PanelBuilder controls, however, may require additional bytes. If less
than 2 bytes are required, use Bit Array. Most PanelBuilder controls write only 1 element of data. If the
associated Data Type is an Unsigned Integer, this implies 2
bytes will be written by the Tag. However, if tags are assigned
to the Block Write of a Piloted Control List, the number of bytes
written will be a multiple of the states displayed on the list.
Tag: - Data Type implies Packet Bytes should be equal to 4.
Certain PanelBuilder controls, however, may require additional bytes. Most PanelBuilder controls write only 1 element of data. If the
associated Data Type is a Floating Point, this implies 4 bytes
will be written by the Tag. However, if tags are assigned to the
Block Write of a Piloted Control List, the number of bytes
written will be a multiple of the states displayed on the list.
Tag: - Data Type implies Packet Bytes should be less than or
equal to 2. Certain PanelBuilder controls, however, may require additional
bytes. Most PanelBuilder controls write only 1 element of data. If the
associated Data Type is an Bit Array, this implies at most 2
bytes will be written by the Tag. However, if tags are assigned
to the Block Write of a Piloted Control List, the number of bytes
written will be a multiple of the states displayed on the list.
Tag: - The length of the data extends beyond the size of the
packet. If the associated tag is an I/O tag, increase either the Input or
Output Size. If the associated tag is Explicit-Server, the data
size extends beyond the 64 word limit of the Assembly
Instance.
Tag: - The length of the data extends beyond the size of the
packet. Adjust Packet Bytes to at least #. Increase the Packet Bytes assigned to the tag.
Tag: - This tag cannot be assumed consistent or ”atomic”. The
tag’s Message Type is inconsistent with previous tags in this group. Tags have been assigned to a PanelBuilder control that must
be updated in the same data packet. Change the Message
Type so that it is the same as other members of this group.
Tag: - This tag cannot be assumed consistent or ”atomic”. The
Assembly Instance is inconsistent with the previous tags in this group. Tags have been assigned to a PanelBuilder control that must
be updated in the same data packet. Change the Assembly
Instance so that it is the same as the other members of this
group.
Tag: - This tag cannot be assumed consistent or ”atomic”. The
Peer’s Class, Instance, Attribute, or Node Address is inconsistent with previous
tags in this group. Tags have been assigned to a PanelBuilder control that must
be updated in the same data packet. Change the
Explicit-Client message so that it references the same peer
attribute as other tags assigned to this group.
PanelBuilder Device Error Messages
Message Recommended Action
Device: - Cannot be converted to current protocol format. Create a new device entry under the Terminal Setup Dialog.
Device: - Converted to DeviceNet. Default communication
parameters will be used. Update the Communications Setup Dialog to the appropriate
network values. (i.e. Node Address, Baud Rate, etc.)
Device: - Communication settings have never been initialized. Update the Communications Setup Dialog to the appropriate
network values. (i.e. Node Address, Baud Rate, etc.)
PanelBuilder Translation Error Messages
Message Recommended Action
Too many peer accesses. Only 128 Explicit-Client message channels are
allowed per application. Reduce the number of Explicit-Client Tags in your application.
Translation Failure Contact Allen-Bradley for technical support.
