1 ABB AC500 Technical Help Sheet How to setup Communication between Emax Breaker Trip unit and AC500 via ProfiBus. ABB Inc. -1- Revision Date: Feb 17,2009

2 Objective Using AC500 to communicate to Emax Breaker with Profibus. This intermediate level course demonstrates how to connect an AC500 PLC to an Emax Breaker. The student will connect Emax Breaker to a AC500 PLC with provided communication diagrams. The student will also control and monitor Emax Breaker with provided AC500 program (AC500_EMAX_EP010_PROFIBUS.pro). ABB Inc

10 Breaker Setup Procedure Setting the Com Module address, baud rate, and com mode. In the Trip Unit display select <ESC> key. Go to Settings and select Com Module Select the Local option Default password is 0001 Once module is in Local hit <ESC> key to go back until you are prompted to save and confirm changes Go back to com module settings and select Address Set address to Always is 247 Select Baud Rate Set baud rate to 19200kb/s Select Protocol Type Even, 8 data bits, 1 stop bit = E,8,1 Select Addressing Type Select Modbus Standard Place Com Module back in Remote and confirm changes ABB Inc

11 Breaker Setup Procedure EP010 Addressing: Addressing using a handheld programming unit : The address is set on the field bus plug by means of the programming unit. For this purpose the cable of the field bus plug is disconnected from the bus and than connected to the handheld programming unit Addressing via the field bus Note: In this case, the address is transmitted from the controller to the field bus plug via the field bus. Remember that the address associated to the device via the EP010 is stored into the FBP. Therefore, after installation, the new EP010 takes on the same address as the replaced one. For Example: go to any existing device (Like Softstarter or Drive) has node address for example address # 5 and Plug FBP to it then cycle power that device, then after you power the device wait for 2 seconds to store this address in to the FBP then unplug it When a Profibus FBP is used, the EP010 GSD file associated to the connected device is required When a DeviceNet FBP is used, the relevant EP010 EDS file associated to the connected device is required FBP ABB Inc

12 PLC program Controlling the Drive from the PLC Open The PLC Program Go to your program and go to Resources Tab Click on PLC Configuration Right Click on Couplers [FIX] and select Append Subelement then Select CM572 PLC Configuration Couplers [FIX] ABB Inc Resources

13 PLC program Continue Controlling the Drive from the PLC Double click on CM572 On the right window change Run on config fault from NO to Yes In the left window under Resources go to Tools then double click on SYCON.net Select Yes SYCON.net ABB Inc

14 PLC program SYCON.net In the Menu bar go to Network then click on Device Catalog New window will open then click Reload Network ABB Inc Reload

15 PLC program SYCON.net Under netdevice window go expand ABB file then expand Master File and click on CM572 then Drag it to the left window and drop it there Click yes on Board no 1 (Means the CM572 is the first coupler to the PLC) Go to ABB file and expand Salve file then select PDP22-FBP (V1) Drag and drop under CM572 module netdevice CM572 Slave file ABB Inc

16 PLC program SYCON.net Double Click on CM572 go to Device Assignmnet and check mark the CM572-DP Go Bus Paramenters and make sure the Baud Rate is 1500 (Remember that what we setup in the Drive also) Go to Station Table and under Station Change the number to the Node Address ( we selected # 5 as example) then click on apply ABB Inc CM572 Station Table Node Address

17 PLC program SYCON.net Double Click on PDP22-FBP and go to Modules and Select the Trip unit model in our case we are going to select PR122/Pr123/PR332/PR333 then Insert and apply Module ABB Inc PDP22-FBP PR122/Pr123/PR332/PR333

18 PLC program SYCON.net Go to net Connect window then expand CM572-DPM, expand PDP22-FBP then click on PR122/PR123/PR332/PR333 file The variables will be declared in the table PR122/PR123/PR332/PR333 variables ABB Inc

19 PLC program SYCON.net Right click on CM572 after you put the PLC in Stop Mode Then click on connect then download then right click and disconnect Go to the file then save and exit CM572 ABB Inc

20 PLC program Step 10: Controlling the Drive from the PLC Go to your program and Go-online Select Run Mode Two Green Led s should be solid green on Drive PDP22-FBP Note: Go to Resources to see you variables under Global Variables Slot 2 Step 11: Using program HMI interface Notice HMI similar to Keypad To initialize and start Drive Click on stop, then enable and start indicators. Drive should begin to ramp up ABB Inc

21 PLC program Open PLC Program AC500_EMAX_EP010_PROFIBUS.pro Compile and go online ABB Inc

22 PLC Program Operating circuit breaker remotely When you Go online with program the correct breaker address should show on the top left corner of the HMI. Verify Address matches the breaker you want to operate remotely Operating circuit breaker remotely Test operation of breaker by opening and closing ABB Inc

23 Evaluation Was hardware connection content defined? Was Profibus Setup instructions defined? Did the PLC program communicate with the Emax Breaker? ABB Inc

24 Summary The Course provided a quick-start guide to interfacing an AC500 PLC to Emax Breaker Profibus communication protocal was used to communicate between the AC500 and Emax Breaker The Profibus memory map (GSD File) linked PLC memory addresses to Emax Breaker commands and parameters. The PLC program provided a user interface to execute commands and retrieve Exam Breaker parameters. ABB Inc
