We have 15 devices connected to 1 serial to ethernet converter and then this converter is connected to the computer.The protocol these devices are using is Modbus.The problem is when we try to establish the connection with these devices using Modbus TCP/IP driver from the computer,all the device works fine except 1.This one device shows the error "device block request [ 401200 to 401213] responded with exception 7". I have checked the modbus specifications which shows the description of this code is "Read Exception status".But this description is not useful to find out the exact reason of the problem.Can any one help me out to find out the possible reason for this problem and how can we solve it.
Thanks.
