Not having access to software is like not having a multimeteter and wanting to know the voltage in a circuit. <s> Doing a tongue test? </s> Firstly get the manual for the PLC: SIMATIC S7 S7-1200 Programmable controller. There in is a description of the LED states and its meaning. Unfortunately "flashing" is not enough of a description. Electrically check if the voltages are at the levels you would expect. Confirm by using the manual where the power connections are. Disconnecting field wiring may be needed. Disconnect the pressure transducer first to see if there is a change. Also check if the pressure transducer gives out a voltage / current. Do you have an HMI connected to the system? Perhaps their is a PLC centred diagnostic available. You need to read the "diagnostic buffer" of the PLC for a detailed report. You might be able to use Proneta to get the diagnostic buffer. Get that here: PRONETA Basic 3.5 Commissioning and Diagnostics Tool for PROFINET. Otherwise trial versions of the software is available.. but you need to know which version. Beyond these steps: send this voluntary forum wiring diagrams, photos and description of part numbers of the PLC and cards. Alternatively use the "Support Request" link on this page to connect to the Siemens Support team. Good luck. |

Hey Guys, Power seems to be as it should be, I've tested with multimeter. There is a Siemens HMI attached.
