Meaning
The protocol number where an error has been detected
is stored.
• 0: No error
• 1 to 128: Protocol number
• 65535: Unidentifiable
If the value 65535 is stored, the following reasons are
considered.
• The setting that the current version of LCPU does not
support is written.
• The protocol setting data is collapsed.
The setting type of the protocol setting data where an
error has been detected is stored. (The value will be
stored only when the written protocol number is within
the range of 1 to 128.)
• 0: Packet setting or component setting
• 1: Protocol detailed setting
• 65535: Unidentifiable
If the value 65535 is stored, the following reasons are
considered.
• The setting that the current version of LCPU does not
support is written.
• The protocol setting data is collapsed.
The packet number where an error has been detected is
stored. (The value is stored only when the setting type is
0 (packet setting or component setting).)
• 0: Transmitted packet
• 1 to 16: Received packet number
• 65535: Unidentifiable
If the value 65535 is stored, the following reasons are
considered.
• The setting that the current version of LCPU does not
support is written.
• The protocol setting data is collapsed.
The component number where an error has been
detected is stored. (The value is stored only when the
setting type is 0 (packet setting or component setting).)
• 1 to 32: Component number
• 65535: Unidentifiable
If the value 65535 is stored, the following reasons are
considered.
• The setting that the current version of LCPU does not
support is written.
• The protocol setting data is collapsed.
This register stores the number of protocols in the
protocol setting data registered through the predefined
protocol support function
0: No registration
1 to 128: Number of protocols
