Connect 240Vac 60 Hz power to the power terminal block using the information in International models—building power
termination..
COMMUNICATIONS WIRING
All communications wiring is made through knockouts adjacent to the communication ports. Prior to connecting cables, ensure
that the grommet bushing has been installed for each knockout. Employ strain relief on the communication wiring to prevent
damage to the controller.
Ethernet
Two, female 10/100-Mbit Ethernet connections are provided
on the controller’s NPM6E processor module. These RJ-45
connectors are labeled LAN1 (PRI) for primary and LAN2
(SEC) as secondary. Use a standard Ethernet patch cable for
connecting to an Ethernet switch or hub.
The factory-default IP address for LAN1 is 192.168.1.12
n
,
where the last numeral
n
matches the
last digit
in the
controller’s
serial number
, and the subnet mask is
255.255.255.0. By default, LAN2 is disabled.
NOTE: Only LAN1 is supported if configuring the con-
troller for
WEBs R2
(LAN2 is
not
supported).
NOTE: If configuring for WEBs-AX, LAN2 can be used in
addition to LAN 1. Typically, you
only use LAN1
(primary port), unless you have a specific appli-
cation for the other LAN2 port. For example, iso-
lating a driver’s network traffic, using LAN2. Do
not
use LAN2 as the primary port.
If enabling LAN2, note LAN1 and LAN2 must be
connected to
different IP subnets
. Further, note
that a JACE controller
does not provide IP routing or
bridging
operation between the two LAN ports.
Refer to the “Install and Startup” documents in the “Related
Documentation” on page 1 for further details on changing the
controller’s TCP/IP configuration.
Serial
There are six serial ports on the WEB-645-AX, located at the
bottom of the board (see Fig. 2). From left-to-right, ports are
two RS-485 (COM3 and COM4), two RS-232 (COM1 and
COM2), and two more RS-485 (COM5 and COM6). The RS-
485 ports are two-wire with shield and are optically-isolated;
the two RS-232 ports are not isolated.
RS-485
Four RS-485 ports use 3-position, screw terminal connectors.
Each port’s terminals are (from left-to-right) shield, plus (+),
and minus (–). Use shielded, twisted-pair cabling wired in a
continuous multidrop fashion to other RS-485 devices,
meaning “minus to minus”, “plus to plus,” and “shield to shield.”
Connect the shield to earth ground at one end only, such as at
the controller. Follow the field device manufacturers’
recommendations regarding cable type, gauge, maximum
number of devices and maximum cable lengths.
By default, RS-485 ports are
unbiased
. However, you can
change this. See “RS-485 port biasing,” page 11.
RS-232
Two RS-232 serial ports are on female (socket) RJ-45
connectors at the bottom of the circuit board. Wire using an 8-
conductor flat silver satin stranded cable with standard male
(plug) RJ-45 connectors. Connect the flat satin cable
(maximum distance 50 feet) through the enclosure knockout
nearest the port. This “straight-through” cable is then
connected to a socket-to-socket type RJ-45-to-DB-9 adapter.
The controller is a serial DTE device, such that another DTE
device (for example, PC) requires a “null modem” adapter
(part number 10148, optional item). If connecting the
controller to a DCE device (for example, modem), use a
straight-through adapter. RJ-45 to DB-9 adapter pinouts.
provides pinouts for both adapter types
