Access port of the module.

Formatting the Module
When you are unable to communicate with a
module, you can, as a last resort, manually
format the module to try to restore
communication. Formatting the module
erases all memory, so you need to transfer
memory back to the module once it is
formatted.
1. Turn the module’s power off.
2. Make sure the module is addressed
correctly.
3. Press and hold the Format button (see
Figure 2 on page 3 for location).
4. While continuing to hold the Format
button, turn the module’s power on.
5. Continue to hold the button until the Error
LED flashes three times in sync with the
Run LED.
6. Release the Format button.
7. Transfer memory to the module. Refer to
“Transferring Memory” on page 5.

show the status of certain functions. Table 2
