Hello fazal; I am sorry I am not familiar enough with Cemat to say if there is an integrated block to do your conversion from kW to kWh. However, here are 2 solutions available from Siemens support that could help you out: First, Simocode Pro code to generate a pulse signal for every kWh measured : http://support.automation.siemens.com/WW/view/en/25575791 Connect the relay output of the Simocode (or the equivalent Profibus input) to a counter (an IEC counterSFB1 would probably be best, they have a larger range and are easier to handle, no BCD values) or an ADD_I instruction; you will simply read thje accumulated value for kWh in the output of the counter or adderinstruction. This solution has the advantage of using the resolution of the Simocode, so the PLC only has to count and keep up... Second: a totalizer function provided by Siemens: http://support.automation.siemens.com/WW/view/en/23061633 |
