good day everyone! I'm also currently working on a project with MM430 drive controlled through PLC via profibus. I was successful in controlling and reading data ( status word, voltage, current, etc..) from the drive, but when im trying to read the Totalized Energy Consumption ( r0039 kWh) i always encounter the same problem asJanneman1234stated. ![]() can anyone help us out with this, a sample program is much appreciated. thanks in advance!!=)

As discussed in https://www.automation.siemens.com/tf/WW/en/Posts/73366#top Certain parameter values cannot be transmitted due to internal software problems. These include 32 (power) and 39 (kWh used - on MM430, MM436 and MM440). All other permissible parameters may be transmitted without problem using P2051. In order to transmit these values it is suggested that the parameter be read using the PKW part of the message (i.e. by requesting the parameter value in the usual way), rather than using P2051 So in order to get Energy data, it is recommended to USE PKW and read directly Parameter no r039 Regards Devesh Vithani |

As said, you need to use PKW to get those parameters For More help please read Operating Instructions: MICROMASTER PROFIBUS Optional Board And also /tf/WW/en/Posts/18809 |
