2500C-2572-B Quick Start Guide
Physical Installation
To insert the module into the I/O base, hold the top and bottom of the bezel, align the circuit board with the guide,
and slide the module carefully into the slot, pushing it all the way into the base. If you have inserted the module
correctly, you will feel a slight increase in resistance as the module mates with the base backplane connector. Once
the module is fully seated in the slot, tighten the captive screws at the top and bottom to hold the module in place.
To remove the module from the I/O base, loosen the captive screws, and then slide the module out of the base. Take
care not to damage the connector at the back of the module when inserting or removing the module.
Connecting the Ethernet Cable
Insert the 8 pin (RJ-45) plug on your unshielded twisted pair cable into the RJ-45 jack on the 2572. Push the plug into
the jack until the plug clicks into place.
Initial Power On
Apply power to the base. The module should begin a power-up sequence during which the LEDs and the Multi-
Segment Display will change state.
Module Startup
After power is applied to the 2572-B module, when the Reset button is pressed, or when the module is restarted by
software or the reset switch, the module will begin the startup procedure. After the application firmware is running,
all LEDs and MSD segments will be illuminated for approximately one second (multicolor LEDs will be red for ½ second
and green for ½ second), and then will be turned off. This serves a display test and as an indication that module
startup is in process.
AutoStart Mode
If the A
UTO
S
TART
option is selected (SW4), the module will start up using the IP address stored in flash. If the startup is
successful, all module network services, including the embedded web server, CAMP Server, Modbus TCP Server, and
the Ethernet IP server, will be enabled. After startup, the MS LED should be S
TEADY
G
REEN
and the Multi-Segment
Display (MSD) should display the module IP address and subnet mask (in CIDR format). The NS LED should be either
S
TEADY
R
ED
if a duplicate IP has been detected (indicating the module IP address is the same as another IP Host on the
network) or S
TEADY
G
REEN
if no duplicate has been detected. If the module is not in this state, see the
CTI 2572-B
Installation and Operation Guide
for troubleshooting instructions.
PLC Start Mode
If the PLC
S
TART
option is selected (SW4), the module will start up in a limited function mode using the IP address
stored in flash, enabling only the embedded web server. Then it will wait on the PLC logic to set the IP address and
enable the application servers using the Start Network Services command. While the module is waiting on the PLC
command, the MSD should display the characters “PLC” interleaved with the IP address read from flash. The NS LED
should be F
LASHING
R
ED
if the IP address read from flash memory is a duplicate of another IP host on the network or
