I can't figure out what I'm doing wrong with regards to the Modbus Control Word (STW) to the V20 in TIA Portal 14. I am trying to run the motor by setting the bits according to the HMI screen that Siemens provides in their example project, and also understand what is going on with the V20. Exactly how do I read and write the status and control words? I went online on the PLC and took these screenshots: 1. Online TIA Portal 14 hardware configuration. 2. Online CM1241 modbus module settings in TIA portal. 3. Online Modbus block made by Siemens 4. Watch list with control word and status word. 5. Screenshots of the Siemens manual on Modbus control and status word. Please see attachment. ------------------------------------------------------------------------------------------ AttachmentModbus_TIAPortal14_ControlStatusWord_Issues.zip (405 Downloads) |
