Ethernet Expansion Module
The HMIECENT expansion module adds 10/100 MB Modbus
TCP ability when plugged into the expansion slot of a 6", 8"
or 10"
HM
i
unit. Up load and download programs and com-
municate to other Modbus TCP devices. No need for patch
or crossover cables as this module auto-detects and adjusts
for proper operation.

I/O Expansion Modules
The HMIEC0806 and HMIEC1612 are 14 and 28 discrete I/0
expansion modules providing 8 DC inputs and 6 relay out-
puts or 16 DC inputs and 12 relay outputs. Plug this module
into the available expansion slot on the back of the
HM
i
unit
(not available on the 4" model) and it’s ready to use. No need
for a separate PLC controller as it is built into the unit. Com-
bine operator interface and logic into a single platform —
use HMISOFT to build both the ladder logic and OI program.
