Hello Amit_86, 1) is it mendatory to connect pulse encoder signal to loss in Weight Controller?? or else if i have connected Encoder & it got faulty then wheather controller will keep working in Auto Operation? My answer: It is not necessary to connect a pulse encoder to the Siwarex FTC module for a loss in weight application. A pulse encoder is only necessary if you have a belt scale application to detect the belt speed. 2) How the actual feedrate will be calculated if there is no encoder signal connected to Siwarex?? My answer: The actual feedrate will be calculated with the decreasing weight value on the load cells each 10 ms. 3) What are the command to parameterize to Start Auto operation of Lossin Weight System & to Stop Auto operation of loss in weight System? My answer: You have to execute the commands 165 and afterwards 164 during the commissionig so that the Siwarex FTC module finds automatically the device characteristic curve (command 165) and the PID parameters (command 164). After these commands are executed, it is not necessary to stop anything. Please see also the chapters 2.6 …2.8 into the attached file. 4) is it possible to get the actual status of DO in Siwarex FTC in its Scale DB??? i mena if first output is 1, then how can i get the status of that output in my program because i need to turn on another DO of SM322 Module connected with Siwarex FTC module in S7300 PLC Rack. Regarding this 4th point i tried to check the status in its scale DB but it actual Status show me False value all the time. My answer: It is not possible to see directly the DO. But you defined a special function to these DO, e.g. DO1 = “Dosing on”. You can find these functionalities into the DR32, e.g. the bit “Dosing on”. That means you can use directly the bits of the DR32 into your Step7 program. You can find a Step7 example project for the FTC as loss in weight on the internet with the following link: http://support.automation.siemens.com/WW/view/de/26046093 Best regards Siwarexi AttachmentSIWAREX_FTC_L_Quick Guide _V3.1.pdf (208 Downloads) |
