No. 1213	Re: EZL-70 no Modbus response	2013-09-09

Hello. This is a technical support team of Sollae Systems. The data what you said [ 00 00 00 00 00 06 01 03 00 00 00 01 ] is Modbus/TCP. But I think that your serial device needs to get Modbus/RTU data. Please send to the Modbus/RTU data. Have a nice day. Thank you. > Hannes wrote: > ------------------------------------ > Hello, > I configured my EZL-70(A) with my network and I’ve made a connection to send a Modbus request. When I am sending the request FC3 like descripted I didn’t get any response. I am sending 00 00 00 00 00 06 01 03 00 00 00 01 but without any response. > > I have my device connected to the network, power comes over JP18 and JP19 and a jumper is on JP13 on RS485. The red and the yellow light are illuminated. I tried to send the request from different tools, but on no one I got a response. . I am always able to ping the EZL-70. I even checked with wireshark and the request was sent successfully to the device, but no reaction from the device. > What could be my mistake? > > Thanks > Hannes >
