Tags Write Delay in between KepwareEx to Mitsubishi iQ-R32 PLC

I am using KepwareEx6.15 with Mitsubishi iQ-R32 PLC + RJ71EN71 module.

Kepware Channel and Device configuration point out to the RJ71EN71 module (SLMP TCP/IP port)

I have created SLMP TCP/IP 40 ports for connecting the same PLC+RJ71EN71 module with KepwareEx6.15 multiple channel and devices for limit the tags in each devices for quick poll. 

I have active client connections with KepwareEx is 120 and Active tags more than 3000 with scan rate 100ms. I am facing the challenge to write back 200tags values from kepwareEx to PLC it took more than 40 secs. 

 

the below information were my testing observations.

 

Scenario 1: When i restart the Kepware and disconnect the active client connections and maintain one channel & device with 200 tags the write back time is 6secs.

 

Scenario 2: When i restart the Kepware and loaded the active clients connections and maintain the one channel and device with 4000 tags and write back time of 200 tags is 60secs

 

Scenario 3: When i restart the Kepware and loaded the active clients connections and maintain the multiple channel and device with 4000 tags and write back time of 200 tags is 40secs - 60secs(random time observing)

 

all the above testing duty cycle maintained as 2

scan rate of write back 200 tags as 20ms 

Scan mode first time all three scenario respect tag based

Scan mode second time all three scenario respect client specified

 

Note: When i am increase the tags in Kepware and i felt the performance of KepwareEx i.e write back the values time get increased.

 

I want to achieve the write back 200 or 300 tags within 2 to 4 secs.

 

I am expecting a solution in this forum hope anyone face this issue or have any ideas please suggest me.

Greetings,

We need a case opened for this query to look into this issue further. We would require OPC diagnostics to see how the clients are interacting with the runtime/driver. if the clients are not optimized or issuing sync requests, that can cause a lot of problems, especially with 120 clients
