CarlosFri Posts: 13 Rating: (0)	I having problems communicating a 6ED1052-1FB08-0BA1 with a Circutor CEM M ETH energy meter (http://circutor.es/en/products/metering/partial-consumption-energy-meters/ac-measurement2/cem-m-eth-detail). I need to read the voltage data from the energy meter. I followed this tutorial https://support.industry.siemens.com/cs/es/es/view/109746315 only changing IP and start address (1842 for voltage at Circutor CEM M ETH), but the data read is 0. If I connect directly the computer to Circutor CEM M ETH and use modbus software to ask for data it works OK. Thanks!

CarlosFri Posts: 13 Rating: (0)	ixo65 Try the project in the attachment. You must set by the devices your IP addresses. Thank you very much for your cooperation, but It doesn't work. 0V at the three phases. I changed logo (192.168.0.8) and circutor CEM M ETH IPs (192.168.0.50) at your program. More info: If I connect the Circutor to my ethernet network without LOGO connected I can ask for modbus data like voltage by computer software, but when I connect the LOGO to the network, Circutor ETH stops answer with data when I ask by software. What is more, if then I disconnect LOGO, the Circutor ETH still giving no data, I have to restart it.

CarlosFri Posts: 13 Rating: (0)	Some info abouth the CEM M ETH: http://circutor.es/docs/FT_CEM-M_EN.pdf http://docs.circutor.com/docs/M060A01-65.pdf http://docs.circutor.com/docs/M060B01-03.pdf I'm not sure about client server question you do, I'm a completely beginner in modbus. I configured the CEM M ETH as a client because is what a I read at this example: https://support.industry.siemens.com/cs/es/es/view/109746315 and this is a similar situation Thanks your for your answers

CarlosFri Posts: 13 Rating: (0)	The communication of CEM-M-ETH with computer works with the software, the problem is the configuration of the LOGO. This is the answer when is ask for voltage 1ph: (732 in HEX), answer 8CF in HEX C:\mbus>mbus x192.168.0.50 p502 010407320002 DB9700000006010407320002 DB9700000007010404000008CF 100.00%
