Order NO.31.001040
The S7-TCP/UDP interface can be used to acquire data from an S7 controller through the standard network card of the ibaPDA PC using the TCP/IP or UDP protocol. This requires the connection to be configured and data transmission to be programmed in the controller. The signals to be measured are selected by arranging the values in data blocks (DB) whose data structures are defined by the module types of ibaPDA. Subsequently, the data blocks are sent to the ibaPDA PC as telegrams with S7 communication blocks. Each module is assigned to a connection. You can create up to 256 connections on the side of ibaPDA. On the S7 side, the maximum number of connections depends on the CPU type. This type of data acquisition has the main advantage of not requiring any special hardware if the controller already features an Ethernet connection.
