A - 2
I-E96-213A
®
Engineering Workstation (EWS) with PC-90 Ladder Software or
CAD/TEXT.
NOTE: Be careful when using either PC-90 Ladder Software or
CAD/TEXT to avoid deleting blocks and/or adding blocks in the mid-
dle of existing ones. Refer to the note preceding Step 3 of the
backup cycle for a further explanation.
See Figure
in Operation section for the front panel LED
positions. The status of LEDs 7 and 8 is indicated for each step
of the backup and primary cycles. Refer to Table
for LED
error codes.
For example, do not reset an MFC before its CPU LED 7 lights.
When lit, this LED tells the user that a successful copy of the
configuration has been made. Resetting the MFC before this
copy is complete could result in unpredictable MFC operation
and/or loss of output data.
NOTES:
1.
In some applications, you may not be able to see the LEDs of
remote MFCs. In these applications, use the data from the second
module status byte.
2.
The value of bit 7 depends on the communication module resid-
ing in the same module bus as the MFC.
The specific interface device determines how module status is
acquired. For example: using an operator interface station
(OIS), the status is polled by selecting the module in the PCU
status display selected from the system status display. With an
EWS using CAD/TEXT software, the problem report option
must be selected. Note that this option does not continuously
poll for module status. The EWS operator may have to poll the
status several times until the final module status condition
arises for the step of the on-line configuration cycle. The
WARNING
Strict adherence must be made with regard to the rules set
forth in this document. Follow all steps in the sequence given
and at no time change configurations or remove the module
before the LEDs instruct you to do so. Failure to heed this
warning and follow proper procedures could result in unpre-
dictable MFC operation and/or loss of output data.
ATTENTION
Les procedures decrites dans ce document doivent etre suiv-
ies a la lettre. Respecter l'ordre des etapes, et ne jamais
apporter de changements a la configuration ou retirer le mod-
ule du chassis de montage avant que les temoins DEL ne
l'autorisent. Tout ecart a la procedure decrite peut mener a un
fonctionnement anormal du MFC et/ou entrainer la perte des
signaux de sortie.
