11.3 MECHATROLINK-III I/O Module Settings
11.3.7 Command Status
11-34
SBUSY
• Definition
1: Transient state
0: Steady state
• Description
The status of SBUSY will be 1 while changing from an asynchronous status to slave CPU
synchronized status.
SBUSY changes to 0 when slave CPU synchronized status is reached.
SYNCRDY
• Definition
1: Slave CPU synchronization preparations completed.
0: Slave CPU synchronization preparations not completed.
• Description
SYNCRDY changes to 1 when the execution conditions for slave CPU synchronization are
met.
SYNCRDY will be 0 if the execution conditions for slave CPU synchronization are not met or if
the SLVSC command control bit in the slave is ON (SLVSC = 1).
SYNC
• Definition
1: Slave is synchronized.
0: Slave is asynchronized.
• Description
SYNC changes to 1 when slave CPU synchronized status is reached. At that time, SBUSY
will change to 0.
CMD_ALM
• Definition
These bits show the command error status.
• Description
These bits show the I/O command error status. This status is independent from COMM_ALM,
D_ALM, and D_WAR.
CMD_ALM automatically changes to 0 (normal) when a defined command is received after a
command error has occurred.
Communications are not affected even if a command error occurs.
The alarm/warning classification of CMD_ALM depends on the product specifications of the
I/O Module.
