No. 1212	EZL-70 no Modbus response	2013-09-09

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
