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 ControlNet 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 two BNC communication connectors. 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) 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
Testing
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.

7) Output Short Circuit Protection (Status Input Bits)
Status Input Bits report the integrity of the load being driven by the output driver. They must be mapped to the
scanner as part of the Input Size Value. Please refer to the table below for Status Input Bit action during fault
condition:
Output Type Output State Fault Condition Status Bit
No Fault 0
ON Fault -
Short Circuit, Over Temp/Over Current 1
No Fault 0
Valve Solenoid Coil Driver or
Sinking (NPN)
Discrete Outputs OFF Fault -
Open Load 1
No Fault 0 Sourcing (PNP)
Discrete Outputs ON Fault -
Short Circuit, Over Temp/Over Current 1
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.

11) Configuration with RSLOGIX 5000
When commissioning your ControlNet node, 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
Node Address, Assembly Instance, Size and Configuration must be entered.
