Siemens S7-1500 & Ignition Communication Slow

Hello Experts,

I am Using Siemens S7-1500 Series PLC & Ignition V7.9.
I done the configuration of driver & created tags Total around 2500 tags i am using in my project, communication is ok but it take around 5 sec time to update.

if any change in PLC (bits status or integer value etc) takes around 5 sec to update on ignition. how to resolved this problem.

Thanks…

Far too little information here to answer your question.
What driver are you using (Processors embedded OPC-UA or Ignitions lagacy driver)?
What is the connection between the gateway and the processor?
How are the tags organized? Polling a single data block with 2500 tags makes a huge diference to polling 2500 spreaded over different memory areas.
What is your scan group configuration?

Hi Chi,

  1. PLC side : I am using PLC embedded OPC-UA server.
  2. Ignition Side: I am using driver Siemens S7-1500(Connect to Siemens S7-1500 PLCs over Ethernet) under devices.
  3. All 2500 tags are from different data blocks & Inputs area.
  4. I am using default scan group of ignition.

Thanks

These statements are contradictory…
