Ethernet Communication
An Ethernet port enables the IDP-800 to be polled over a LAN/Distributed Control System and provide
values of system parameters monitored by the DECS-200, DECS-200N, DECS-250, or DECS-250N.
Figure 2 serves as a general illustration of how the IDP-800 can be used to retrieve DECS data over an
Ethernet LAN. The IDP-800-A and IDP-800-C’s 10 Base-T Ethernet interface connects to a LAN through
a standard RJ-45 modular jack. This jack is located on the bottom of the display.

IDP-800 Modbus registers for the available DECS functions are listed in the Modbus Communication
chapter. Specific information about the Modbus communication protocol, as it is employed by the DECS,
is provided in Basler publication 9360100990 (DECS-200), 9388800990 (DECS-200N), 9440300990
(DECS-250), and 9440500990 (DECS-250N).
An Ethernet port (Com 3) on the DECS-400 enables communication with the IDP-800 at higher speeds
than possible through the DECS-400 RS-485 port. An Ethernet switch is used to route IDP-800 and
DECS-400 communication over a LAN. A general connection scheme for IDP-800 and DECS-400
communication over an Ethernet LAN is illustrated in Figure 3.
