Appendix 6.8 Emergency Stop Alarms (EMG)
IV - 105
EMG Emergency stop LINK
Details
An emergency stop occurs when the FROM/TO instruction is not executed within 500ms.
Remedy
- Execute the FROM/TO instruction one or more times every 500ms.
The time in which no interrupt request is issued from MELSEC is measured and stored in the following
R registers:
R10190: Current timeout counter
R10191: Maximum timeout counter after power ON
R10192: Maximum timeout counter after system is started up (this is backed up)
Details
MELSEC is in error and reset states.
Remedy
- Check the MELSEC states.
Details
The contents of MELSEC-specific code area in buffer memory have been damaged.
Remedy
- Check the MELSEC states.
Details
PLC serial link communication has stopped.
(Note) When "WAIT" is entered in the PLC serial link, only the preparation sequence has been
established before the communication stops. It is supposed that the settings of the serial link
parameters "#1902 Din size" and "#1903 Dout size" are incorrect or the "#1909 Tout (ini)" set-
time is too short in basic specification parameters.
Remedy
- Check the CC-Link card wiring and the external sequencer transmission.
- Check the link communication errors shown on the diagnostic screen.
- Correct the settings of the serial link parameters in basic specification parameters.
EMG Emergency stop WAIT
Details
The preparation sequence is not sent from the master station. Otherwise, the contents of the received
preparation sequence are inconsistent with those of the parameters, so that the usual sequence
cannot be started.
(Note) When "LINK" is also entered for the PLC serial link, refer to "Note" in the section, "LINK".
Remedy
- Check that the CC-Link card switch setting and wiring as well as the external sequencer
transmission are normal.
- Check the diagnostic screen for link communication errors.
EMG Emergency stop XTEN
Details
The CC-Link card is operating incorrectly.
Switch/parameter settings for the CC-Link card are incorrect.
Remedy
- Replace the CC-Link card.
- Correct the switch/parameter settings for the CC-Link card.
EMG Emergency stop LAD
Details
The sequence program has an illegal code.
Remedy
- Correct any illegal device Nos. or constants in the sequence program.
