Replacing a Controller
A microSD/SDHC card can be used to quickly commission a replacement controller in the unlikely event that
an existing controller fails. The card rapidly configures the replacement with the original controller’s IP address,
firmware, configuration, and strategy.
Preparing the card
requires PAC Manager R9.0 or higher. You must prepare the card in advance and then keep it
in a safe place in case the controller fails.
The
replacement controller
must have exactly the same part number as the old controller (for example, a
SNAP-PAC-S1-W must be replaced by a SNAP-PAC-S1-W), and it must have minimum firmware R9.0a and
loader 6.0a. See
to check versions.
CAUTION:
Use the commissioning card only to replace a controller; it assigns the new PAC controller the same IP
address as the old one.
Prepare the Card In Advance.
1.
Put a blank card into the controller that you may need to replace.
2.
Copy configuration data as follows:
a.
Open PAC Manager if needed. In the main window, click the Inspect icon
.
b.
In the Device Name field, type the name (or IP address) of the device. Click Status Write.
c.
In the Operation Command list, highlight Store configuration and IP settings to microSD.
d.
Click Send Command.
The controller’s IP settings and all configuration data are saved to the card in a file located at
/sdcard0/opto22/config/config.cfg.
