Hello,
I have an application where Kepserver EX6 is used to read the present value of a temperature controller (Autonics TF33) which has RS-485 connection. Moxa NPort 5150A acts as gateway for the device to the Kepserver. The diagram of devices are attached. Currently, I have good quality of connection to the modbus address of the device, but reading is 0. Furthermore, in order to get clear picture, inside the NPort Web Console, I set the IP Address to its default (192.168.127.254) and operation mode set to TCP (Device is TCP Client) where destination IP address is the NPort IP Address. Details are attached also. Then, inside the Kepserver, I assign channel as Modbus TCP/IP ethernet with port number as same as written in Moxa (i.e. 502). Then, the modbus address I took from the manual of the device (attached).
Any thought/help on this would be great appreciated. Thank you
