MECHATROLINK Communications Control
Section 6-3
The operation of the Axis Communications Status Flag depends on the unit
version of the PCU as shown in the following table
With unit version 1.3 or earlier, once MECHATROLINK communications have
been started by establishing connections, the Axis Communications Status
Flags will not change unless communications are disconnected (including
Unit errors that required disconnection).
With unit version 2.0 or later, the Axis Communications Status Flags will turn
OFF after connections have been established whenever axis operation
becomes impossible due to a communications error (synchronous communi-
cations alarm or communications alarm).
Refer to
6-3-3 MECHATROLINK Communications Errors
for information on
errors that occur when establishing connections.
The Axis Communications Status Flags are allocated in CIO 1522 + (unit
number
×
25).

Unit version 1.3 or
earlier
• The flags will turn ON when
connections are made for
the axes registered in the

• The flags will remain OFF
when MECHATROLINK
communications cannot be
started when connections
are made for the axes regis-
tered in the scan list.
• The flags will turn OFF if
MECHATROLINK communi-
cations stop because the
axis is disconnected.
• The flags will turn OFF if a
Unit error occurs that
requires disconnection.
Unit version 2.0 or

• The flags will turn ON when
connections are made for
the axes registered in the
scan list and MECHA-

istered in the scan list.
• The flags will remain OFF
when MECHATROLINK
communications cannot be
started when connections
are made for the axes regis-
tered in the scan list.
• The flags will turn OFF if
