Overview
The Quantum controller and the STAHL IS1 Remote I/O system communication through Modbus TCP Ethernet implicit message by using the I/O scanner service of the controller. A generic Modbus TCP I/O device entity (which is the counterpart of the generic device instance create in the Application) allows you to perform the communication mapping with the controller.
Configuring the Topology
Step
1

3
Action
In the Topological Explorer , create a Quantum controller entity and configure it with the I/O scanner enabled.
Configure the client memory properties with suitable values.
NOTE: The configuration of the STAHL IS1 Remote I/O system is performed outside of EcoStruxure Process Expert.
Create a Modbus TCP I/O device entity by using the $EGenericDeviceHW template and configure its properties.
The following figure shows the properties of the generic Modbus TCP I/O device entity after configuring its parameters:
EIO0000002403.10
The parameters are calculated as follows in the context of the STAHL IS1 Remote
I/O system:
• ReadLength = Total number of read/input registers. The actual number is 49 but it is rounded off to 50.
• WriteLength = Total no of write/output registers. The actual number is 8 but it is rounded off to 10.
For detailed information on ReadAddress and WriteAddress parameters, refer to the Operating_instructions_IS1_ModTCP manual .
Connecting to the Control Network
Create an Ethernet network and make a physical connection with the controller and the generic device entities.
