LE_ISO_on_TCP library for TIA portal V16
The LE_ISO_on_TCP library allows customers to enable their PLC program to publish data from a supported Siemens PLC to Litmus Edge via TCP Broadcasting.
This allows for faster data collection compared to traditional TCP/IP request-based communication.

Description
Publishing data from a Siemens PLC to Litmus Edge via TCP Broadcasting allows one to read data at the cycle time of the PLC – something that is not possible with drivers based on TCP requests. This makes it possible to monitor data with a very short life span on the PLC time, without having to slow down the PLC, or having to store them separately.
This can be especially effective for monitoring Boolean values, which can change within a couple of PLC cycles – up to changing between just two cycles, and are therefore easily missed by a request-based communication which works on a set schedule (as a PLC cycle is typically far below the 100ms span, most request-based drivers are not capable of executing within that span)
