Lab #5, Implementing a DeviceNet Network, Part 2 page 1 of 21 MFET 374 Manufacturing Integration I Spring 2010 Laboratory Assignment #5 Implementing a DeviceNet Network, Part 2 Objectives: In this assignment you will explore some of the more advanced features of DeviceNet. In this assignment you will work exclusively at the offline area. Preparation: It is assumed that you have completed the laboratory assignment – “Implementing a DeviceNet Network, Part 1”. Background: Figure 1 illustrates the DeviceNet network you implemented in laboratory assignment #4. Figure 1 – DeviceNet Network Implemented in Laboratory Assignment #4 Your DeviceNet network should look like Figure 1.

Lab #5, Implementing a DeviceNet Network, Part 2 page 2 of 21 Figure 2 illustrates the desired DeviceNet network from an RSNetworx for DeviceNet perspective: Figure 2 – RSNetworx for DeviceNet Screen After Network Browse In laboratory #4, you created the alias tags shown in Table 1. Table 1 – Alias Tags Created in Laboratory #4 Device: Alias Name: DeviceNet Photo-eye I_PE1 DeviceNet Inductive Proximity Sensor I_Prox_DN ArmorBlock Inductive Proximity Switch I_Prox_ArmorBlock Green pushbutton on offline device panel I_PB0 Red pilot light on offline device panel O_Red_PL Blue stack light O_Blue_SL Red stack light O_Red_SL In laboratory assignment #4 you developed a PLC program which functioned as follows: 1) Whenever the green pushbutton (I_PB0) is pushed, the red light (O_Red_PL) on the offline device panel must be ON. When PB0 is released, the red light must switch OFF. 2) When the photo-eye’s (I_PE1) output is ON, the blue stack light (O_Blue_SL) must be ON. Otherwise, the light must be OFF. 3) When the DeviceNet inductive proximity (I_Prox_DN) sensors output is ON OR the inductive proximity switch (I_Prox_ArmorBlock) that is connected to the ArmorBlock is ON, the red stack light (O_Red_SL) must be ON. Otherwise, the red stack light must be OFF.

Lab #5, Implementing a DeviceNet Network, Part 2 page 3 of 21 Phase 1: In this phase you will modify some of the DeviceNet parameters associated with the photoelectric sensor (node #5). Proceed as follows : 1) The first step is to get your network back up and running as follows: Inspect the network and make sure it is wired as shown in Figure 1. Power up the network. Open up RSNetworx for DeviceNet and go online. After the network is browsed, your RSNetworx for DeviceNet screen should be identical to Figure 2. Using RSNetworx for DeviceNet, perform an “upload from network.” Test the PLC program. Make sure it operates as it did in laboratory assignment #4. 2) We can monitor the status of the DeviceNet photoelectric sensor using: The LEDs built into the photoeye. In the RSLogix5000 tag database.
