Hardware

Each ECM-2 module is equipped with two Ethernet ports which use an RJ-45

connector. Port 2 is typically used for communication with the local HMI on the

door of the DECS-2100 enclosure. Each ECM-2 (on per channel) would be linked

from Ethernet port 2 to an Ethernet switch also linked to the local HMI.

The ECM-2 supports 10Base-T and 100Base-T wiring standards.

The user could connect their plant SCADA system or other Ethernet master to the

Ethernet switch providing the signal to the HMI. However, the same IP addresses

would need to be used for the ECM2 modules. Alternately, the user could connect

the plant SCADA to Ethernet port 1—either directly or through a separate Ethernet

switch. Due to communication issues, Basler Electric prefers the use of Ethernet

port 1 for communication with external plant devices and the use of Ethernet port

2 for the local HMI only.
