Dear Experts I have original project sent from china. actually the problem is that i have S7 200 CPU 224XP CN installed in my machine and Siemens SMART LINE 700IE(touch screen) is also installed. now the problem is that PORT0 is connected to Siemens Drives RS485 communication and HMI is connected on PORT1. I have five motors for different purpose. it is a mixer machine. when i set parameter for different motor speeds on HMI. parameter sets and save. when i want to start any motor from HMI. hmi is showing motor start but physically motor is not start. the frequency which i applied on HMI all my siemens Micromaster 420 display showing same frequency but drive enable signal from plc is not coming means plc is not giving any output. PLC has five output connected through relays to Drives Enable signal. Outputs are Q0.0 to Q0.5. When i manually applied enable signal on drive then Motors Runs Fine and i can change speed from HMI. Example i manually applied enable signal for MOTOR1 and on HMI i give 20 Hz then motor is running on 20 hz. when i changed motor frequency on HMI 40Hz then motor runs on 40Hz but when i remove manually applied drives enable singanal then plc is not giving any output. i connect my laptop on PORT0. it connects and online but some plc block is locked. so i can not see online status. when i connect my laptop to PORT1 . i can not go online. plc is not connected with my laptop on PORT1. PORT1 is that port on which HMI Cable is connected. Now i am attaching Original PLC Program. can any chinese or other expert can unlock blocks for me or can give me any idea to understand complete program. AttachmentPROGRAME.zip (368 Downloads) |
