The INSEVIS PC350V....PC1567T series represents a unique convergence of compact design and powerful functionality in the world of panel-mount PLCs. At first glance, it is a brilliantly compact 3.5-inch touch panel. But within its metal front frame, it houses a fully integrated Siemens S7-300 compatible CPU. This combination of visualization and control in a single, space-saving unit makes it an ideal solution for applications where panel space is at a premium or where an additional, intelligent operator interface is needed within an existing S7 control network.

The core strength of the INSEVIS panel PLC lies in its seamless integration with the Siemens automation ecosystem. The integrated CPU, available in 512kB (type V) and 640kB (type P) work memory variants, corresponds to an S7-315-2PNDP in terms of command range and performance. This means users can program and maintain these devices using the industry-standard Siemens STEP7 (Simatic Manager/Classic) or TIA Portal software, protecting existing engineering investments and know-how. For those seeking an alternative, the WinPLC7 software offers a compatible programming environment. The HMI visualization is created with VisuStage, a free (for small projects) software tool with a large library of graphical objects, making it easy to design professional operator interfaces.

Despite its compact dimensions, the INSEVIS panel PLC boasts an exceptionally rich set of onboard communication interfaces. Standard features include Ethernet supporting S7 communication, TCP, and UDP; Modbus (both TCP and RTU); CAN (supporting both CANopen and Layer2); and RS232/485 ports for free ASCII protocol. This comprehensive suite of protocols makes the device particularly well-suited for use as a data logger, aggregating information from various sources, or as a protocol gateway, enabling communication between disparate industrial systems. For applications requiring more specialized fieldbus connectivity, the device can be optionally equipped with Profibus DP V0 (master or slave) or a Profinet IO Controller interface.

Flexibility extends to I/O and storage expansion. The PC350V model serves as a compact controller without onboard peripherals, addressing external I/O through its various interfaces. For applications demanding local I/O, the PC1567T variant provides seven onboard slots capable of accommodating up to 112 digital or 70 analog I/O points, all within a depth of just 104mm. Both models can be expanded using INSEVIS remote I/O racks via the CANbus interface or by integrating Helmholz I/O modules. A Micro SD card slot supports cards up to 8 GB, enabling extensive data logging, program backup, and easy field upgrades. The front panel is rated to IP65, ensuring reliable operation in harsh industrial environments, and the firmware can be marked with a customer's logo starting from a quantity of just one unit.

Applications

The INSEVIS PC350V....PC1567T panel PLC is a versatile platform suited for a range of automation tasks:

• Entry-Level Machine Control: A cost-effective all-in-one solution for small to medium-sized machines.
• Data Logging and Gateway: Perfect for collecting data from multiple sources and bridging between different protocols (e.g., S7 to Modbus).
• Distributed Control Systems: Serves as an intelligent remote terminal unit (RTU) or a supplementary operator panel within a larger S7 network.
• Retrofit Projects: An ideal replacement for legacy operator panels and controllers, offering modern communication capabilities.
