Modbus Master | Connections

Once the I/O interface has been configured as desired, the user will have to connect points in the model to points in the driver by using the designated HYPERSIM sensors. The driver's connectable points depend on the number of analog and digital inputs and outputs that the slave has.

The connection points are classified in the following categories:

Coils

Discrete Inputs

Holding Registers

Input Registers

Operation Error Codes

Triggered Operation

Under each category, the configured operations will show-up with the names that have been given by the user for each of the configured slaves.

Operation error codes from each slave and for each operation can be captured in the model using the operation error code connection points.

The additional 'Connected_SX' is utilized in the model to indicate whether the respective Modbus Slave SX (where X increases with each slave) is connected or not.

If 'Triggered Operation' is enabled for a given operation, a connection will be available to allow the user to control the time and frequency where the read/write operation will be executed. The user will be required to create a connection in order to control the trigger. A transition from 0 to 1 on the triggered port will execute the configured operation. However, it will not be executed if there is no other transition from 0 to 1 on the connected triggered port.
