Parker PAC, Installation Manual, Page: 185 / 197

If the PAC cannot find the PROFINET slave module, be sure to double check the mechanical installation
instructions in Chapter 6.
If the PROFINET Master cannot communicate with the PAC:
1. Check if the Slave is set up correctly. Refer to the configuration section of Chapter 6.
2. Check if the Master is set up correctly. Refer to the documentation of the master.
3. Check if the configuration of the Master and Slave match. To configure the Controller, a GSDML
file (device description file) is required. The settings in the used Controller must comply with the
settings in the Device to establish communication. Important parameters are Station Name,
Vendor ID, Device ID, and Input and Output Data Bytes.
4. Double check the cabling between the Master and Slave. Try a different cable.
Secure Digital (SD) Card
The PAC comes with a Secure Digital (SD) Card from the factory. It is highly recommended that you only
use SD cards purchased from Parker. Replacement SD cards can be purchased from Parker using part
number 33-026611-01.
When you order a PAC, the SD card comes from the factory loaded with the Operating System and other
necessary files to run the PAC. When you save your project with Parker Automation Manager, it will also
be stored on the SD card. Do not remove or modify any files on the SD card unless instructed to in the
documentation. This card is used as a removable drive and provides non-volatile memory storage.
Although this card is removable, it must be inserted in the controller at power up and cannot be removed
while the PAC is powered on.
The SD card is not recommended to be written to during run time. This could corrupt the SD card and
cause failures on the next power cycle. If you need to log or store data, we recommend using the USB
port.
If you are having difficulties powering up the PAC (the Error LED is Red), it could be associated with the SD
Card. The SD Card has been specially formatted for the PAC. Make sure you are using a Parker SD card
and it has all of the necessary files on the card. You can use the Flashback Utility to restore the SD card
back to factory settings that includes the proper format. Refer to the Flashback Utility section of this
installation guide for more details on how to use this feature. It may be necessary to try a replacement SD
card if you continue to have power up issues that are associated with the faulty card.
Note: SD Cards over 32 GB are not compatible.
