iMCC I/O Scanner Application

This presentation contains the preliminary design concepts for the installation of a data concentrator acting as the I/O scanning client in a iMCC. This device will then act as a server to third party clients.

The client device link configuration:In this example, the client would target the data concentrator at the IP address 192.168.2.61.

The control devices link configuration:In this example, the Tesys T is supplying 2 registers of information to the client and the ATV61/71 is supplying 3 registers. The client is able to write to 1 register in the Tesys T and 3 registers in the ATV61/71.

The communication status and control variables available to the client application:

In this example, the client has access to one Boolean variable per device to monitor it’s communication health and also can disable the communication to it with another Boolean variable.

The Fallback control of the devices.In this example, the Data concentrator monitors the status of the communication with the Client and disables all the device communications in case the client is not communicating anymore. In that case, the devices will go to their fallback state as configured individually. The Client needs to write alternate values to Client_WD faster than 5 seconds.

The Tesys T exchanges.In this example, the client will receive the registers 455 and 456 for complete status and average current of the motor and will write the register 704 commands it.

The ATV61 or 71exchanges.In this example, the client will receive the registers ETA and rFrd for logical status and actual speed of the motor and will write the register CMD and LFRD for commands and speed reference to it.

The Tesys T logic example from a PLC.In this example, the logic is using the variables as configured before. The client will need to apply something similar.

The ATV 71 logic example from a PLCIn this example, the logic is using the variables as configured before. The client will need to apply something similar.
