ProSoft Industrial Communication Solutions: Engineering Overview for System Integration
May 08, 2026
ProSoft Technology: Integration Challenges In modern industrial automation systems, engineers frequently face a mixed environment of legacy fieldbus networks, proprietary platforms, and Ethernet-based industrial protocols. ProSoft Technology focuses on resolving this integration gap by providing protocol conversion modules and industrial gateways that enable direct communication between systems such as Logix-based controllers, Siemens PROFINET devices, CAN networks, Modbus-based instruments, and legacy ControlNet or serial infrastructures. The core engineering value of these products lies in avoiding full control system replacement, instead shifting protocol translation and data mapping to dedicated communication hardware.
Platform In-Rack Communication Architecture ProSoft in-chassis modules are designed for systems and integrate directly into the 1756 backplane, allowing communication processing to occur at the rack level rather than through external gateways. These modules typically handle real-time data exchange between controller tags and external industrial networks with update cycles that can reach tens of milliseconds depending on configuration and network load. In engineering applications, this approach is commonly used to map PROFINET or Modbus device data directly into controller tag structures without modifying existing logic, which significantly reduces commissioning time in retrofit projects.
CAN Bus and ControlNet Integration for Legacy Systems Recent ProSoft communication modules extend support into CAN Bus and ControlNet environments, both of which are still widely deployed in automotive, packaging, and older industrial control systems. CAN interfaces support standard CAN 2.0A and 2.0B frame formats with baud rates up to 1 Mbps, making them suitable for deterministic machine-level communication. ControlNet modules support scheduled, deterministic communication with typical update rates in the low millisecond range and redundant media options such as coaxial or fiber configurations. These technologies are particularly important in modernization projects where complete replacement of legacy infrastructure is not economically or operationally feasible.
PROFINET to Integration in Hybrid Systems One of the most common integration challenges in global manufacturing environments is connecting Siemens PROFINET devices to Logix-based controller systems. ProSoft PROFINET interface modules address this by acting as either IO Controllers or IO Devices, depending on system architecture. In real-time RT communication mode, cycle times can be configured in the low millisecond range, allowing sufficient performance for most discrete manufacturing and process control applications. From an engineering standpoint, this eliminates the need for OPC-based indirect communication in time-sensitive control loops and allows direct deterministic data exchange between heterogeneous platforms.
Industrial Remote Connectivity in Utility Applications In utility and distributed infrastructure systems, ProSoft remote connectivity solutions provide secure access between field assets and central SCADA platforms. These systems typically rely on VPN or cellular-based industrial gateways that support protocols such as DNP3, Modbus, and IEC 60870-5-104. Communication latency is dependent on network conditions but is generally sufficient for telemetry and supervisory control applications. This architecture is widely used in water treatment facilities, electrical substations, and pipeline monitoring systems, where remote visibility and reduced on-site maintenance are key operational requirements.
Conclusion ProSoft Technology provides a structured approach to industrial communication challenges by focusing on protocol conversion, legacy system modernization, and secure remote connectivity. For engineers, the primary advantage is not replacing existing automation infrastructure, but enabling controlled interoperability between incompatible systems. This makes ProSoft particularly relevant in industries where long equipment lifecycles, mixed vendor environments, and continuous operation requirements define system design constraints.
