4.1SM-EtherCAT module information

4.1.1Bus media

The SM-EtherCAT option module incorporates two x 100 BASE-TX RJ45 interfaces.

4.1.2Cabling considerations

To ensure long-term reliability it is recommended that any cables used to connect a system together be tested using a suitable Ethernet cable tester, this is of particular importance when cables are constructed on site.

4.1.3Cable

Cables should be shielded and as a minimum, meet TIA Cat 5e requirements.

	Cabling issues are the single biggest cause of network downtime. Ensure cabling is
NOTE
	correctly routed, wiring is correct, connectors are correctly fitted and any switches or
	routers used are rated for industrial use. Office grade Ethernet equipment does not
	generally offer the same degree of noise immunity as equipment intended for industrial
	use.

4.1.4Maximum network length

The main restriction imposed on Ethernet cabling is the length of a single segment of cable. The SM-EtherCAT module has two 100BASE-TX Ethernet ports, which support segment lengths of up to 100m. This means that the maximum cable length which can be used between one SM-EtherCAT port and another 100BASE-TX port is 100m however it is not recommended that the full 100m cable length is used. The total network length is not restricted by the Ethernet standard but depends on the number of devices on the network and the transmission media (copper, fiber optic, etc.).

	The EtherCAT system designer must consider the impact that the selected network
NOTE
	structure will have on performance.

4.2 Module grounding

SM-EtherCAT is supplied with a grounding tag on the module that should be connected to the closest possible grounding point using the minimum length of cable. This will greatly improve the noise immunity of the module.
