I have been given the task of monitoring an old Siemens S5-100U that is operating a critical peice of equipment. We are in the process of upgrading this equipment, but until that occurs I need to attempt pulling live data off of the PLC for data logging. I have been able to communicate with the PLC and pull off the existing program. I can see which data bits I would like monitor on the code. Does anyone know if you can, or how to monitor or collect data live?
Thanks in advance.
