Getting Started
This is a brief document designed to quickly get you started setting up your valve manifold with an integrated
Numatics’ G2-2 series EtherNet/IP
TM
or Modbus TCP communication node.
1) Initial Unpacking and Inspection
1) Examine exterior of package for signs of damage. Report any damage to shipping carrier.
2) Remove wrapped manifold assembly from box.
a) Remove manifold assembly from anti-static packaging
b) Retain documentation for installation and configuration
3) Examine manifold assembly for any shipping damage such as:
a) Bent pins or connectors
b) Report any damage to shipping carrier immediately
4) Examine manifold assembly for proper ordered configuration. (Valves, I/O, Protocol, etc.)
2) G2-2 Introduction
Below is an example of a 2012 series valve manifold. This fieldbus manifold series is capable of addressing a
total of 224 I/O. The manifold can be viewed as having two sections to it, the
Valve Side
and the
Discrete I/O
Side
. The
Valve Side
supports a maximum of 32 solenoid coils and the
Discrete I/O Side
supports a
maximum of 6 modules totaling 192 Outputs, 96 Inputs, or various combinations. The communication
module has a RJ45 communication connector. The power module has a 4-pin power connector. Pin-outs for
these, along with I/O connectors, are labeled on the side of the respective modules.

4) MCM - Manual Configuration Module (Optional)
The MCM is the module that allows the user to manually enable user definable options such as self test mode,
bit mapping offset (Modbus TCP ONLY) and byte swapping (Modbus TCP ONLY), without the need for
software configuration. If software configuration is preferred, this module is not necessary
. The MCM
consists of two DIP switch sets (SW1 and SW2) and two rotary switches (SW3 and SW4).

MCM Settings (Modbus TCP ONLY)
DIP Switch Settings (SW1)
Offset:
Switch Setting Description
SW1-7 Off*
Enable Output offset of 400 hex or 1024 dec (Some software programs deal
with a pre-determined offset for the Output data table. This setting allows
the user to work with the offset.)
SW1-7 On
Disable Output offset. (This setting allows the user to disregard the
offset.)
Bit swap:
Switch Setting Description
SW1-8 Off*
Disable I/O bit stream swapping (Some software programs reverse the
way the I/O bits are presented to the node and thus the bit mapping may
be reversed or swapped from the expected mapping scheme.)
SW1-8 On Enable I/O bit stream swapping
*Factory Default Settings
DIP Switch Settings (SW2) – No Function
Rotary Switch Settings (SW3 and SW4) – No Function

5) Self-Test Mode
An internal diagnostic tool can also be enabled using the optional MCM module. This tool allows the user to
confirm that all of the Inputs and Outputs on the manifold are fully functional without needing a network
connection or controller. There are two test modes that the user can choose using SW2-8. The “Output” test
mode tests all the outputs by sequentially turning them ON one at a time. The “Input/Output” test mode
tests the inputs by causing all of the outputs to toggle between even and odd values when any input is made.
To use the Self-Test Mode, the user must first set some initial conditions using the MCM module. Follow
these steps to obtain the needed initial condition settings. Remember to remove power from the manifold
before making changes to the MCM when setting these initial conditions.
1) Disconnect power and air from the manifold!
2) Record current MCM settings.
3) Set the rotary switches to 99 (SW3 and SW4).
4) Make sure that SW1-5, SW2-1, and SW2-7 are in the “ON” position.
5) Select the desired test mode with SW2-8 (see table below)
Switch
T
esting
Mode
Setting Description
Output Off Sequentially turns all the outputs ON and OFF.
SW2-8
Input/
Output
On
Causes all of the odd outputs to come on and stay on until an
input is made. When an input is made, the outputs will toggle to
the even outputs.
6) Make sure that all of the other switches are in the “OFF” position.
The initial conditions are now set. To enable the Self-Test Mode, apply power to the manifold and make the
following changes within 5 to 10 seconds:
1) Set SW2-6 to the “ON” position.
2) Set SW2-7 to the “OFF” position.
Self-Test Mode is terminated by removing power to the unit. Remember to return the MCM settings to their
original settings to return the communication node to normal operation.
!
Air should be disconnected to the manifold when attempting to run the
Self-Test Mode to prevent unwanted motion.
Communication lines should be disconnected before attempting to run the
Self-Test Mode.

8) Ground Wiring
All Numatics Inc. communication nodes should be grounded during the installation process. These grounding
guidelines can be found in National Electrical code IEC 60204-1 or EN 60204-1. There also is a,
“ATTENTION: CONNECT TO EARTH GROUND FOR PROPER GROUNDING OF UNIT”, label
attached to the chassis ground connection point on the G2-2 series communication node housing. This label
also points out where the grounding guidelines can be found.
Proper grounding will alleviate and prevent many intermittent problems
with network communication.
When grounding to a machine frame, please ensure that the machine frame
itself is already properly grounded.
Better grounding can be achieved when larger diameter (lower gauge) wire
is used.

Discrete I/O Module(s) Power Jumper
All of Numatics, Inc., G2-2 I/O modules have a selectable power source jumper. This jumper determines
which Aux. Power connector pin will power these modules.
This option allows the user to select how each specific module will be powered during different conditions
(i.e. E-Stop). Each I/O module can be set-up independently allowing individual Output and/or Input
modules to remain active if needed.
Power Rating
Maximum system current capability is 8 amps. Care should be taken not to exceed 8 amp draw
through the 0VDC common pin (Current through all +24 VDC Pins combined).
Discrete I/O current draw is dependent on the device(s) connected. It is critical to know what these
values are in order to remain safely within the 8 amp limitation.
Loads should not draw more than 0.5 amps of current from any one individual discrete output point.

The standard power jumper configuration for all Output Modules is “SP”.
The standard power jumper configuration for all Input Modules is “UP”.
At any given moment in time, the combined current draw through
+24VDC (Valves & Outputs) pin and
+24VDC (Node & Inputs) pin
cannot exceed 8 amps. Therefore, the combined value of the external fuses
on the two +24VDC pins should not exceed 8 amps.
The internal fuses are installed to protect against fire damage due to
catastrophic failure of internal components. External fuses are
recommended for protection against power supply failure, over-current
conditions, etc…

14) IP Address Configuration
The IP address of the Numatics G2-2 Ethernet node may be configured via several different methods:
DHCP/ BOOTP
Manual Configuration via DIP switch
Integrated Web Page Configuration
ARP/PING command
A.)
DHCP/ BOOTP
The node is shipped from the factory with DHCP/BOOTP feature enabled. This allows a DHCP server to
automatically set the IP address to the node when connected to the network, or a BOOTP server to establish
communication to the node and set the IP address. These addressing methods require that the unique MAC
ADDRESS of the node is known. The MAC ADDRESS can be found on the label located on the node cover
(see above). It will be different for every node. When DHCP/BOOTP is enabled and a DHCP server is
found, the IP address, Subnet mask, and gateway are automatically configured by the DHCP server.
The DHCP/ BOOTP setting can be enabled or disabled via the nodes integrated web server. Simply log on to
the node with any web browser and go to the configuration page.

B.)
Manual Configuration DIP switch
The manual configuration DIP switch provides an easy way to configure the node’s IP address. The switch
represents the binary value of the last octet in the IP address. When all switches are set to OFF, it is disabled
and other means of setting the address must be used. DIP switch configuration settings require power to be
cycled before changes take effect.
IP address: 192.168.0.X
Subnet Mask 255.255.255.0
Gateway address: 0.0.0.0 (no gateway set)

Web Page Configuration
The Numatics G2-2 Ethernet node has an imbedded web server. This server can be accessed via any standard
web browser program. If the IP address of the node is known, the “Node Configuration Page” for the node
can be called up and the configuration parameters updated. If the IP address of the node is not known, it can
be set using any of the previously described methods. Please note that the PC, where the web browser is
installed, must be correctly configured for operation with the appropriate network IP ranges and Subnet
settings that match the G2-2 Ethernet node. Consult appropriate personnel before changing your computer’s
network settings and always record previous settings before attempting changes!
Below is a representation of the “Node Configuration Page” which is stored in the Ethernet node.
IP address, Subnet Mask, Gateway Address, SMTP server address and DHCP/BootP enabled selections can all be configured
from this page. These parameters will be programmed in the node’s non-volatile FLASH memory once
“UPDATE CONFIG.” is clicked.
Modifications to the
Configuration Page
settings require power to be cycled before changes
take effect.

D.)
ARP/PING Command
ARP (Address Resolution Protocol) and PING are DOS commands that can be used to set an IP address.
This will require a PC equipped with an Ethernet Network Interface Card (NIC). The IP address will be
stored in the node’s non-volatile FLASH memory after it is set. No power cycle is necessary. Follow these
steps to configure an IP address using the ARP/PING commands.
1) Use the ARP-s command to configure the IP address from a DOS window.
arp -s <IP address> <MAC address>
Where: <IP address> is the IP address that the node is to be set to
<MAC address> is the unique MAC address of the node where the IP address is to be set
(see label on cover)
Example: arp -s 192.168.6.35 00-15-24-00-00-38
2) Use the PING command to send the IP address to the node.
ping <IP address>
Where: <IP address> is the IP address that was previously used in the “arp -s” command.
Example: ping 192.168.6.35
3) Use the ARP-d command to remove the static entry from the PC ARP table.
arp –d
Example: arp -d
!
The ARP command automatically configures the subnet mask to
255.255.255.0 (thus the first three octets of the IP address will be the same as
the PC executing the command).
When the ARP and PING commands are used, the DHCP/BOOTP is
disabled.
The parameters set in the node are programmed in non-volatile FLASH
memory. They will NOT be lost during loss of power.

15) EtherNet/IP
™
Configuration with RSLOGIX 5000
When commissioning your EtherNet/IP
™
network, specific values must be entered in the “Connection
Parameters” section for the “Assembly Instance” column with regards to “Input Size”, “Output Size”, and
“Configuration”. The “Size” values are determined from the actual physical configuration of the manifold
(i.e. how many and which I/O modules are installed on the manifold). The size values are a minimum value;
higher values can be used if future manifold I/O expansion is required. Below is a sample screen shot taken
from Allen Bradley’s RSLogix 5000 programming software, it shows where the appropriate values for the
IP Address, Assembly Instance, Size
and
Configuration
must be entered.
