Connectivity
The connectivity layer is the central location for signal interconnections of external devices and systems that exchange process data with SIMATIC PCS neo via a so-called open communication protocol. Initially, it is not important which protocol is used in this case. The new engineering concept in PCS neo has been designed so that data exchange can take place independent of the protocol, process engineering and hardware. This concept is based on the signal assignment for signals that are usually connected via the SIMATIC S7-410 CPU I/O.
The following advantages result:Process engineering is independent of the protocol in the equipment hierarchy. A new internal element, the Connectivity resource or CNYResource, has been introduced for this. The element is assigned in the respective EQH folder and represents the interface between hardware and process.
Independent hardware engineering
The option to change the communication protocol retroactively.
The following protocols are supported:OPC UA client on the PCS neo M&C server as communication carrier
IEC 60870-5-104 client on the PCS neo M&C server as communication carrier
OPC UA client and Modbus TCP client on the SIMATIC CN 4100 as communication carrier
TCPCon as communication between SIMATIC PCS neo controller and SIMATIC CN 4100
In future versions of PCS neo, additional protocols will be added that are implemented in the connectivity layer using the same principle
The following functions are supported:Creation of CNYResources
Deletion of CNYResources
Assignment of a communication protocol
Assignment of a communication carrier (information on where the protocol is running)
Changing the view, organized either by protocols or by communication carriers
Definition of the communication addresses
Definition of the address names (optional)
import of communication addresses
Option of automatic assignment of process signals to communication addresses
The following limitations must be observed with PCS neo V5.0:Modbus TCP client/server protocol as block library for the S7-410 and S7-4100 CPU is currently not supported by the connectivity layer. Configuration is still possible in the equipment hierarchy via CFC
COM as block library for the S7-410 and S7-4100 CPUs is currently not supported by the connectivity layer. Configuration is still possible in the equipment hierarchy via CFC
PCS neo M&C OPC UA server is currently not supported by the connectivity layer. Configuration is still implemented in the equipment hierarchy
only PCS neo M&C server and SIMATIC CN 4100 are currently supported as communication carrier
