Ethernet/IP Adapter

A new PLC adapter has been introduced that talks to (Rockwell Automation) Allen Bradly Logix series controllers. This adapter communicates over Ethernet and requires Ethernet Communication Module. Addition of this adapter should eliminate the need of dedicated OPC server. The adapter supports read, write and tag discovery features that are at par with OPC UA adapter.


Another PLC adapter that talks to Siemens S7 series controllers has been introduced. The adapter communication requires Ethernet Communication Module. Again, this adapter will remove dependency on OPC server. It supports read and write tag features. The adapter features are at par with Modbus adapter.

Improved OPC DA Adapter

The improved OPC DA adapter is more robust, scalable and handles OPC connectivity issues in better fashion. Its design model has been changed from Push to Pull, making it predictable and better configurable.

Faster Modbus Adapter

A single threaded Modbus TCP adapter is now replaced with multi-threaded Modbus adapter. This will help reading data from multiple Modbus sources concurrently without getting impacted from individual source's performance.

Auto Scalable Pull Adapters

This feature auto determines the best configuration param values for thread-pool considering machine capability.

Key Value Store for managing Adapter State

A persistent KV store has been introduced to store adapter state like last sent or last scanned values. This will help sending consistent event data across machine or process restarts and removes discrepancies arising due to volatile in memory state. This KV store is also available as part of adapter interfaces to meet local state storage requirements.

Syntax Validation and IntelliSense Support for JavaScript Widgets

An in-built JavaScript IDE has been added for JavaScript controls like Script Adapter inputs or Derived tags. It quickly validates the syntax of scripts, also provides better suggestions and frequently used code snippets.
