INSTALLATION
32 Parker Automation Controller Installation Guide
Fieldbus Communication Module (optional)
An optional Fieldbus Communication Module is available with the PAC Controller in order to provide
PROFINET I/O data via a PCI Express interface. Refer to Chapter 6 for more information on the
configuration or installation of the PROFINET Slave option.
Note: The PROFINET communication modules are shipped with their firmware already loaded.
Attaching Cables
Ethernet, EtherCAT, and Fieldbus Communication Cables
WARNING: Do not install Ethernet communication cables in the same conduit or
cable tray with AC power wiring, motor leads, or any other high
potential switching currents.
To ensure reliable communications with the best performance possible, the cabling components used
must conform to US standard EIA/TIA 568 or European standard EN50173-1 Class D.
Category 5 (CAT5 or preferably CAT5e) cable is recommended for Ethernet and EtherCAT
communications. The maximum allowed channel length is 100 meters or 328 feet.
The cable must not be kinked or bent too tightly (the bend radius should be at least four times the outer
diameter of the cable).
Either shielded or unshielded cables may be used. Consider using shielded cables in electrically noisy
environments. All shielded cables must be grounded for safety and effectiveness and a continuous shield
connection maintained from end to end. Ground loops may develop when there is more than one ground
connection and the difference in common mode voltage potential at these ground connections can
introduce noise into the cabling.
