Hi guys,
My customer have a project with 2 servers (A and B') redundant with single active configuration and " without internal variable switching" is unchecked. When he manually switched (A>>B, B>>A), sometimes PcVue was freezed / stacked and forced close.
Question: What does "Variable VAR.AK2.EP420.RWZK product by SERVER1 - No response from watch request " that come from event viewer means. He can ping both machines and disabled the firewall.
TQ in advance

Hi,
About the event viewer message, it means there is a networking subscription problem during switching.
What is the industrial protocol used ?
Could you check if the server and client list are correctly configured for the variable ?
Is there any Scada Basic script launched when a server become active ?
thanks

Hi Brice,
Answers:
--------
1. They used Genisys protocol (serial)
2. Yes, the variables are correct
3. There is a SBasic script launched on startup. LAN("SET SERVER ACTIVE") to do server switching (A>>B , B>>A)
