CTI The 2500P-ECC1 can be installed in a CTI 2500 Series

Installation

Module Installation

The 2500P-ECC1 can be installed in a CTI 2500 Series or SIMATIC® 505 PLC base. Before installing the module, remove

AC power from the base. Using the guides, align the circuit board with one of the I/O slot connectors in the base. Slide

the 2500P-ECC1 module into the rack until the connector seats. Then use the thumbscrews to secure the module in

the rack.

Making Ethernet Connections

The 2500P-ECC1 module provides two Ethernet port connectors on the front panel.

Both ports connect to a three port switch on the module circuit board.

The third port of the switch is connected to the ECC1 module microprocessor.

This design provides additional flexibility in connecting to the Host Controller and the network.

The switch circuit also provides hardware protection against network traffic storms.

The ECC1 module must have an Ethernet path to the Host Controller and the network containing

the devices with which it will communicate.

Direct Connection to the Host Controller

If a single 2500P-ECC1 is installed in the same base as the Host controller, an Ethernet cable

(Cat 5 or Cat 5e) can be used to connect one Ethernet port on the ECC1 module directly to

the Ethernet port of the 2500 Series® controller.  The other port is then connected to the

network switch.

An advantage of this method is that the embedded switch on the 2500P-ECC1 can provide

broadcast storm protection for the 2500 Series® programmable controller.

Connection via a Network Switch

If multiple 2500-ECC1 modules are communicating with the Host Controller, they should be

connected via an external Ethernet switch.

In this example, port 1 of the ECC1 should not be connected to the network. However, you

could directly connect a laptop PC to this port for programming or maintenance tasks.

Apply power to the ECC1 Module

After installing the module, apply power to the base and observe the module LEDs. 

The expected module behavior will depend on whether you transferred the configuration via

the SD card or you chose to transfer the configuration later via the Ethernet port.
