6.6 REPLACEMENT PROCEDURE

6.6.1 Impact on I/O Point Configuration

When an I/O Card is replaced with another I/O Card, it is not necessary to reconfigure the ROC.

If any points or their parameters need to be changed, you can use the ROCLINK configuration software

to make the changes off-line or on-line. If you want to minimize “down time,” before you replace the

card, you can make the needed changes (except for ROC display and FST changes) off-line by first

saving the ROC configuration to disk. Modify the disk configuration, replace the card, and then load

the configuration file into the ROC.

To make changes on-line, replace the card, proceed directly to the configuration display for the affected

points, and modify parameters as needed.

CAUTION

If one or more FSTs, or higher-level points such as a PID loop or AGA Flow, are

configured in the ROC, be sure to reconfigure them according to the changes in I/O

points. Operational problems will occur if you do not reconfigure the ROC.

6.6.2 Replacing the I/O Card

Use the following procedure to replace the I/O Card. The procedure requires using the ROCLINK

Configuration Software.

CAUTION

There is a possibility of losing the configuration and historical data held in RAM

while performing the following procedure. As a precaution, save the current

configuration and historical data to permanent memory as instructed in Section

2.5.2.

CAUTION

When working on units labeled for service in hazardous areas, ensure that the

working environment is currently non-hazardous.
