1.7.5.9
Wiring the MODBUS/TCP Interface
Customers can also use a modified XGS868i that provides a MODBUS/TCP interface to communicate to an internal
network. An optional MODBUS/TCP card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45
connector. To connect the MODBUS/TCP-enabled XGS868i to the network, insert the jack of an RJ45 cable into the
RJ45 connector, route the cable through one of the conduit holes using an appropriate cable clamp, and wire the
other end of the cable to the Ethernet network according to the manufacturer’s instructions. See Figure 13 on page 26.
Note:
The MAC address for a specific XGS868i is included with customer documentation. For more information on
setting up the MAC address, refer to Chapter 6 of the Programming Manual.
1.7.5.10
Wiring the Ethernet Interface
A modified XGS868i can use the Ethernet interface to communicate to a local area network. An optional Ethernet
card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector. To connect the
Ethernet-enabled XGS868i to the network, insert the jack of an RJ45 cable into the RJ45 connector, route the cable
through one of the conduit holes using an appropriate cable clamp, and wire the other end of the cable to the
Ethernet network according to the manufacturer’s instructions. An external connection is required between the
Ethernet option card and the XGS868i’s RS232 connector, as shown in Table 5 and Figure 13 on page 26.
Note:
The MAC address for a specific XGS868i is included with customer documentation. For more information on
setting up the MAC address, refer to Appendix C of the Programming Manual.
