Thanks for your reply
I used timer in Program.Every 10 Seconds , It will set ENQ_ENR (One Pulse) of the Modbus Block for all Power meters at same time.This is the Logical Sequence (Every 10 Seconds Set ,then Reset and After 10 Sec again set) which is running repeatedly.
This Error is always Present (A083) .After Downloading this Error is shifted to Some other Power Meters .
Sometimes After Downloading Program ,If I ping that Particular IP Address of the Power Meter ,I am not getting any reply.
Before Downloading the Program ,I received reply from that same Power Meter.
Is there Any relation between Pinging IP and Logical Sequence of the Program ? I dont think so .
Pinging is used to check the Physical Connection (Ethernet Connection).
Please clarify me.
Sometimes The Led in Scalance Port (Port 9) is blinking ,where Power Meter 1st Connection Starts .
I want to know the reason for this problem is Whether Logical Sequence or any Network Traffic or any Physical Connection Problem?
Please help me to Solve this problem.
