We specify a 32-bit rack connection so that the two words of analog input and two words of analog output data from the 1746-NIO4V module can be transferred via the rack connection. In order to establish a 32-bit rack connection to the 1747-ACN15 chassis, right click on the 1747-ACN15 and choose Insert Connection.
4-16 Application Examples IMPORTANT RSNetWorx allows more than one exclusive owner rack connection type to be configured to a 1747 adapter (e.g. 8-bit exclusive owner, 16-bit exclusive owner, and 32-bit exclusive owner), however only one exclusive owner rack connection can be operational at one time. It is recommended that only one exclusive owner rack connection type be configured to the adapter to avoid contention between multiple connections.
Application Examples NOTE 4-17 There is a 2-word offset for input data for rack connections. Therefore, for this example, the input data for the input module in slot 1 of the remote 1747-ACN15 chassis is written to I:3.3 in the SLC processor’s input image. The starting input address configured in RSNetWorx for this rack connection was I:3.1, but I:3.1 and I:3.2 are used for rack slot status information. Therefore, the actual input data begins after the 2 words of status information. I:3.
4-18 Application Examples You have successfully configured a rack connection to the remote chassis to communicate with the two discrete and one analog I/O modules. At this point you may also configure the state of the outputs in the remote ControlNet chassis when the processor is placed into the Program mode or if communications are lost to the remote chassis. This is optional. The default is to turn all outputs off when one of the two conditions occur.
Application Examples 4-19 Click Apply, then OK. The Connection Properties window closes and the Scanlist Configuration window appears and looks like the following: You have now successfully configured your connection to read/write data between the SLC processor and the remote ControlNet chassis.

IMPORTANT If a rack connection type is changed to a smaller bit configuration e.g.
4-37 By default, outputs in all slots in the remote chassis are reset if the processor is placed into the Program mode or if communications are lost for any reason. Two other choices are offered when one of the two conditions occur. They are: • Hold Last Outputs • Outputs to Safe State Hold Last Outputs holds outputs in their last state if one of the two conditions occur. Safe State allows you to choose the exact state of each output.
4-38 Configuring a Module Connection Next, you need to configure a module connection for the 1746-BAS module. If the previous window is still open, click Apply, then OK to accept the rack connection. Right click on the 1746-BAS module in the Scanlist Configuration window and select Insert Connection. A Connection Properties window again appears. Choose Exclusive Owner-Advanced for the Connection Name. In this case, you must choose M-file addresses for this type of connection.
4-39 You must now configure this connection for the 8 I/O words and the 64 M0/M1 file words. Click on the “Advanced” tab in the Connection Properties window.
4-40 By default, the Chunk 1 Output File is the output image file for the Basic module and the Chunk 1 Input File is the input image file for the Basic module. You must then assign the Chunk 2 Output File as the Basic module’s M0 file and the Chunk 2 Input File as the Basic module’s M1 file. The size for each of these files is 64 words. The total number of words transferred bi-directionally between the SLC processor and the Basic module will be 72.
4-41 Safe State data is available under the Configuration Settings tab. For 1746-BAS module connections, it is recommended that outputs be reset to 0 when the SLC processor is placed into the PROGRAM mode or if communications are lost to the 1747-ACN15. The Hold Last State option is not available for the 1746-BAS. Click Apply, then OK.
4-42 You have now successfully configured your two connections to read/write data between the SLC processor and the remote ControlNet chassis. All that remains is to Save this configuration to the network keeper which, in this case, is the 1747-SCNR. Click on the Save icon or choose the File pull-down menu and select Save. You are prompted to Optimize and re-write schedule for all connections. Click OK, then click YES to the subsequent warning message.
4-43 Create Ladder Logic and Basic Module Programs The final step is to write a ladder program for the SLC processor and a BASIC program for the Basic module. After downloading the program to your processor and to your basic module, place the processor into the RUN mode and run your BASIC program as well. Your programs should now be able to read data from the 1746-IA16 in word I:3.3 and write to the 1746-OB16 in word O:3.2.
4-44 When the Basic module is placed into the RUN mode, any data placed into the SLC processor’s data table beginning with N12:0 is sent to the 1747-SCNR, which sends it to the 1747-ACN15 via ControlNet and then to the Basic module. The Basic module sends the data out PRT1 and this data is looped right back in the Basic module’s PRT2. The module sends the data to the 1747-ACN15, which sends it to the SCNR via ControlNet.

B-6 Understanding Your SLC 500/1746 Control System This section provides specific recommendations to help you install your SLC 500/1746 components. For general installation guidelines, also refer to the requirements specific to your region. SLC 500 System Installation Recommendations • Europe: Reference the standards found in EN 60204 and your national regulations. • United States: Refer to article 70E of the National Fire Protection Association (NFPA).
Understanding Your SLC 500/1746 Control System B-7 The enclosure should be equipped with a disconnect device.To calculate the heat dissipation of your controller, Refer to Calculating Heat Dissipation for Your Control System on page B-34. Spacing Considerations Up to three chassis can be connected (for a maximum of 30 I/O slots). Follow the recommended minimum spacing shown below to allow for convection cooling within the enclosure.
B-8 Understanding Your SLC 500/1746 Control System Preventing Excessive Heat For most applications, normal convection cooling keeps the adapter components within the specified operating range of 0° to +60° C (+32° to +140° F). Proper spacing of components within the enclosure is usually sufficient for heat dissipation. In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure.
Understanding Your SLC 500/1746 Control System ATTENTION ! B-9 Handle the TTL module by its ends, not metallic surfaces. Electrostatic discharges can damage the module. Do not expose the TTL module to electrostatic charges. • Segregate I/O wiring by signal type. Bundle wiring with similar electrical characteristics together. Wires with different signal characteristics should be routed into the enclosure by separate paths.

B-12 Understanding Your SLC 500/1746 Control System IMPORTANT If you are using a dc power supply, interrupt the dc side rather than the ac side to avoid the additional delay of power supply turn-on and turn-off. The dc power supply should receive its power directly from the fused secondary of the transformer. Connect the power to the dc input and output circuits through a set of master control relay contacts.
Understanding Your SLC 500/1746 Control System B-13 Emergency-Stop Switches Adhere to the following points concerning Emergency-Stop switches: • Do not program Emergency-Stop switches in the program. Any Emergency Stop switch should turn off all machine power by turning off the master control relay. • Observe all applicable local codes concerning the placement and labeling of Emergency-Stop switches. • Install Emergency-Stop switches and the master control relay in your system.

B-16 Understanding Your SLC 500/1746 Control System Loss of Power Source The chassis power supplies are designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called “Scan Hold-up time after Loss of Power.” The duration of the power supply hold-up time depends on the number, type and state of the I/O modules, but is typically between 20 ms and 3 s.
Understanding Your SLC 500/1746 Control System B-17 Isolation If there is high frequency conducted noise in or around your distribution equipment, we recommend the use of an isolation transformer in the ac line to the power supply. This type of transformer provides isolation from your power distribution system and is often used as a “step down” transformer to reduce line voltage. Any transformer used with the adapter must have a sufficient power rating for its load.
B-18 Understanding Your SLC 500/1746 Control System Special Considerations The recommendations given previously provide favorable operating conditions for most adapter installations. Your application may involve one or more of the following adverse conditions. Additional measures can be taken to minimize the effect of these conditions. Excessive Line Voltage Variations The best solution for excessive line voltage variation is to correct any feeder problems in your distribution system.
Understanding Your SLC 500/1746 Control System B-19 If you connect a 1746 triac output module to control an inductive load, we recommend that you use varistors for surge suppression. Choose a varistor that is appropriate for the application. The surge suppressors we recommend for triac outputs when switching 120V ac inductive loads are a Harris MOV, part number V220 MA2A, or an Allen-Bradley MOV, Catalog Number 599-K04 or 599-KA04, Series C or later.
B-20 Understanding Your SLC 500/1746 Control System Table B.
Understanding Your SLC 500/1746 Control System B-21 These surge suppression circuits connect directly across the load device. This reduces arcing of the output contacts. (High transient can cause arcing that occurs when switching off an inductive device.) Suitable surge suppression methods for inductive ac load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor.
