5.2 Parameterisation interface (Ethernet) [X1] – socket M12, 5-pin, D-coded
Connect the EMCA to your network or directly to the PC via a hub/switch. Observe
line specification (
è
Device and functional description, GDCE-EMCA-EC-DIO-...).
Recommendation: Use the connecting cable NEBC-D12G4-... from Festo.
Note
Unauthorised access to the device can cause damage or malfunctions.
When connecting the device to a network:
Protect the network against unauthorised access.
Measures to protect the network include:
– firewall
– intrusion prevention system (IPS)
– network segmentation
– virtual LAN (VLAN)
– virtual private network (VPN)
– security at physical access level (port security)

5.3 Power supply [X4]
Warning
Danger of electric shock from voltage sources without safeguarding.
For the electrical power supply, use only PELV circuits (protective extra-low
voltage, PELV) in accordance with EN 60204-1.
Also observe the general requirements for PELV circuits in accordance with
EN 60204-1.
Use only voltage sources which guarantee reliable electrical isolation of
the operating and load voltage in accordance with EN 60204-1.

5.5 STO interface [X6]
The STO safety function (safe torque off ) is described in detail in the document
GDCE-EMCA-EC-S1-.... The STO function should only be used in the manner
described in this document.
Recommendation for initial motor start-up without safety equipment:
– The setup must at least include an emergency stop switching device
– 2-channel switch-off via the control ports STO1 [X6.4] andSTO2 [X6.5]

Commissioning
Communication of the product with a connected PC takes place via the TCP/IPv4
protocol.
Create network connection – example “point-to-point connection”
Requirement:
– The PC is configured as a DHCP client (usually the default setting for PCs).
– The EMCA is configured as a DHCP server (factory setting).
At initial commissioning, connect the EMCA directly to the PC.
Factory setting
DHCP server: active
IP address: http://192.168.178.1
Subnet mask: 255.255.255.0
Gateway: - (A gateway is not assigned.)
