Modbus Comm's - Quantum to Momentum - Time Settings - XXMIT block

I am using a Quantum PLC as a Master to read and write to a Momentum PLC as a single Slave.
Am using the XXMIT block in my Concept V2.6 program code.

The Quantum READS 30 Holding Regisers from the Momentum.
The Quantum WRITES to 3 Holding Registers of the Momentum.

It's working fine except I am not getting responses from the Momentum as fast as I would like.

Could someone help me with some time settings explanations to do with Modbus, the XXMIT block and PLC scan times?

The Quantum (Master) Scan time is : 235 ms
The Momentum (Slave) Scan time is : 27 ms

Momentum Modus Port Delay Time Setting: 230 ms

XXMIT block time settings on the Quantum:

RespTout: 500 ms
StartDly: 10 ms
EndDly: 10 ms

 

You should use all the pins of xmmit to get more information, reply time is not a problem. One of the pins will tell you, you get a new text, and then, you should use a DFB function, to get all the information.
