ETHERNET
Ethernet Port:
10/100Base-T supports
speeds up to 100Mb/sec
Connection Type:
Standard RJ-45
Protocol Type:
MODBUS/TCP
MODBUS Type: Two
independently configurable
RS-485 ports (according to
EIA-485, 1993)
Protocol Type:
MODBUS RTU
Baud Rates: 1200, 2400,
4800, 9600, 19.2k, 38.4k
and 57.6k (user-selectable;
default is 9600)
Parity: Even, Odd or No
Parity (1 stop bit, fixed;
default is No Parity)
Device Address: 1-255
(Default is 1)
Character Timeout:
5, 10, 25, 50, 100, 200 and
255 character times (user-
selectable; factory set to 1.5
character times MODBUS
RTU standard default)
Response Delay:
5, 10, 25, 50, 100, 200 and
255 character times (user-
selectable; factory set to 0
delay)
Data Access Time:
Time to detect or effect a
change in an I/O signal from
a MODBUS master polling a
EMM is the sum of 3 timing
components:
1. Network Communication
Time: Depends on network
architecture and traffic. For
a PC locally networked to a
EMM, this time is negligible
2. Scan Time: Time required
by the EMM to scan real-
time data in all I/O modules
connected to it (see Module
Scan Time specification for
each expansion I/O module
type and add times for each
I/O module connected to
the EMM)
3. Signal Response Time:
Time to convert between
physical I/O and digital
signals (see specification for
specific I/O type)
Isolation: 1000Vrms
between case, input, output,
each MODBUS port, each
discrete input channel and
power, continuous, and
will withstand a 1500Vac
dielectric strength test
for one minute (with no
breakdown). 500Vrms
between analog input
channels.
Power Supply:
20-30VDC
Power Consumption:
24VDC power input, 5W
max.(13W max. with 2 I/O
modules connected)
System:
READY: Green when ready;
Off when not ready
STATUS: Green when OK;
Red when not OK
Ethernet:
(2 LED model)
LINK/ACT:This LED
indicates transmit and
receive activity in addition to
the status of the Link. The
LED will be ON when Link
is good. It will blink when
the transmitter or receiver is
active.
SPEED: This LED is
ON when the Ethernet
connection is 100 Mb/s and
OFF when it is 10 Mb/s.
(3 LED Model)
LINK: Green LED indicates
a network link is present
RX: Flashes green in
response to data reception
TX: Flashes green
in response to data
transmission
MODBUS:
TX1: Green blinks when
Transmit activity on
MODBUS 1 occurs;
Off when no Transmit activity
on MODBUS 1;
RX1: Green blinks when

Indicators
Receive activity on
MODBUS 1 occurs; Off
when no Receive activity
on MODBUS 1; Green solid
when MODBUS 1 connection
reversed
TX2: Green blinks when
Transmit activity on MODBUS
2 occurs; Off when no
Transmit activity on MODBUS
2
RX2: Green blinks when
Receive activity on
MODBUS 2 occurs; Off
when no Receive activity
on MODBUS 2; Green solid
when MODBUS 1 connection
reversed
