Commands and Responses for Controller Link Units
Section 6-5
Response Block
Parameters
Model number, version (response): The Controller Link Unit’s model num-
ber and version are returned as shown below, each 20 characters in ASCII
code. If fewer than 20 bytes of data are used, 20 (Hex) (i.e., spaces) will be
returned for the remaining bytes. In the version numbers shown below, the
spaces are represented by boxes (
@
).

The leftmost “V*” (*: version) represents the Communications Controller data
link level version number. The middle one represents the Communications
Controller network level version number. The rightmost one represents the
Controller Link Unit version number.
Connection Method (Response)
The connection method parameter for the Controller Link Unit (wired or optical
bus/ring) is configured as follows:
Node address (response): The Controller Link Unit’s node address is
returned between 01 and 3E Hex (1 to 62).
Unit Address (response): The Unit address set for the Controller Link Unit
(10 Hex + Unit number), is returned in hexadecimal. Even when there is a Unit
number setting error, the Unit address is returned.
Network Address: The Controller Link Unit’s network address, as set in the
routing table, is returned in hexadecimal. When the routing table has not been
set, the address becomes 00 Hex.
