POINT I/O ControlNet Adapter Installation Instructions

About the Adapter

The POINT I/OTM ControlNet® adapter is a communications interface for POINT I/O modules. The adapter provides an interface for controlling and communicating with POINT I/O modules from a ControlNet network. See Figure 1 to identify the external features of the adapter.

ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated steel DIN rail to ensure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for more information.

Before You Begin
To use your adapter effectively, note the following considerations. · Understand Messaging Class 3 (Explicit Message) requests through the 1734-ACNR or 1734-ACNRK adapter to a specific POINT I/O module may not always receive a response from the I/O module. In the case where the I/O module does not reply to the request, the adapter responds with an error code indicating a timeout. · Establish I/O Connections When you power up a POINT I/O system and establish I/O connections, the outputs transition to the Idle state, applying Idle state data before going to RUN mode. This occurs even when the controller making the connection is already in RUN mode. · Configure Autobaud The adapter cannot reconfigure an I/O module that you previously configured to operate at a fixed baud rate. When you reuse a POINT I/O module from another POINT I/O system, configure the module to autobaud before using it with the 1734-ACNR or 1734-ACNRK adapter.

POINT I/O ControlNet Adapter Installation Instructions
Install the ControlNet Adapter
ATTENTION: You must use series C POINT I/O modules with the 1734-ACNR or 1734-ACNRK adapter. Series A and B POINT I/O modules will not work with the 1734-ACNR or 1734-ACNRK adapter.
To install the adapter on the DIN rail before installing other base units, proceed as follows: 1. Position the adapter vertically above the DIN rail. 2. Press down firmly to install the adapter on the DIN rail. The locking mechanism locks the adapter to the DIN rail. 3. Set the node address on the node address thumbwheel.
WARNING: When you insert or remove the module while backplane power is on, an electric arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation. 4. Remove the safety end cap by sliding it up. This exposes the backplane and power interconnections.
ATTENTION: Do not discard the end cap. Use this end cap to cover the exposed interconnections on the last mounting base on the DIN rail. Failure to do so could result in equipment damage or injury from electric shock.

Set the Node Address
Set the node address using the 2-position thumbwheel switch. Valid settings range from 01...99. Press the + or - buttons to change the number. Network Node Address Thumbwheel

WARNING: When you change switch settings while power is on, an electric arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

Install a Replacement ControlNet Adapter to an Existing System

ATTENTION: You must use series C POINT I/O modules with the 1734-ACNR or 1734-ACNRK adapter. Series A and B POINT I/O modules does not work with the 1734-ACNR or 1734-ACNRK adapter.

WARNING: When you connect or disconnect the RTB with field side power applied, an electric arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

Remove the existing adapter from the DIN rail as follows: 1. Disconnect the ControlNet connector from the adapter. 2. Pull up on the RTB removal handle to remove the RTB. 3. Remove the adjacent module from its base. 4. Use a small bladed screwdriver to rotate the DIN rail locking screw to a vertical position. This releases the locking mechanism. 5. Lift straight up to remove.
Install the replacement adapter on the DIN rail as follows: 1. Remove the safety end cap on the replacement adapter by sliding it up. This exposes the backplane and power connections. 2. Position the replacement adapter vertically above the DIN rail.

POINT I/O ControlNet Adapter Installation Instructions
Verify that the DIN rail lock is in the horizontal position. 3. Slide the adapter down so that the interlocking side pieces engage the adjacent module. 4. Press firmly to seat the adapter on the DIN rail.
The adapter locking mechanism snaps into place. 5. Set the node address on the node address thumbwheel. 6. Insert the end opposite the handle into the base unit.
This end has a curved section that engages with the wiring base. 7. Rotate the RTB into the wiring base until it locks itself into place. 8. Replace the adjacent module in its base. 9. Connect the ControlNet cable to the adapter.
Use a tap to connect the adapter to the ControlNet cable. Do not directly connect the adapter to the coax cable.

WARNING: The NAP port is intended for temporary local programming purposes only and requires the use of a 1786-CP cable assembly. The NAP is not intended for permanent connection. If you connect or disconnect the NAP cable with power applied to this module or any device on the USB network, an electric arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

Value

Up to 17 modules, dependent on backplane bus current draw (17 X 75 mA = 1.275 A, just under the limit of 1.3 A). The actual number of modules can vary. Add up the current requirements of the modules you want to use to make sure they do not exceed the amperage limit of the 1734-ACNR or 1734-ACNRK adapter.
