2-12-7 Status details
When the controller receives the command, the relevant process will be executed, and
the result (status) will be informed to the master sequencer (PLC) side via IWm+8. The
meanings indicated with the statuses are described in this section.
Code 0000 .............................................................................. Command ready
It indicates that the remote command is not executed and can be newly received.
When the command is issued to the controller, the status must be surely 0000. Here,
0000 is set to QWn+8 in order to set 0000 to the status.
Code 0100 ...................................................................... Command executing
It indicates that the controller receives the remote command and is on the way of the
execution.
* If the reset command or other command of a short execution time is executed, the
code 0100 can sometimes not be detected on the sequencer (PLC) side due to the
scan time (10 milliseconds) on the controller side. Take sufficient care to assemble
the sequence program.
Code 0200 ................................................................ Normal end of command
It indicates that the controller normally completes the remote command.
Code 40xx .......................................................... Command error occurrence
It indicates that an error occurs and the execution of the remote command cannot be
normally completed.
The occurrence error number is set at the area of xx.
For example, if the 403E code is sent to the sequencer (PLC) side, it indicates from
3E (hexadecimal) = 62 (decimal) that the command is interrupted by the interlock
from I/O.
* For the error numbers, refer to "Message tables" in "Instruction Manual for Con-
troller".
Code 80xx (81xx) ................................................ X (Y)axis alarm occurrence
It indicates that an alarm occurs in the controller. If any alarm occurs at the X axis,
80xx will be sent to the sequencer (PLC) side, and if it occurs at the Y axis, 81xx will
be sent to the sequencer (PLC) side. The occurrence alarm number will be set at the
xx area.
For example, if the 800F code is sent to the sequencer (PLC) side, it indicates from
0F (hexadecimal) = 15 (decimal) that the alarm of the feed back error 2 occurs.
* To cancel the alarm, it is necessary to turn off the controller power supply. For the
alarm number and alarm treatment method, refer to "Troubleshooting" in "Instruc-
tion Manual for Controller".
