Selection
Panel and PLC in one, or separate
A Panel-PLC combines touch panel and S7 CPU in one device with one IP address, ideal where the controller sits in the cabinet door. Put the CPU on the DIN rail as a Compact PLC and add a Panel-HMI when the panel and the I/O are in different places, or when you add a panel to an existing Siemens S7 controller. All three can be extended with I/O modules on board and in decentral head stations.
S7 Panel-PLCs
Touch panel and S7 CPU in one housing, from 3.5 to 15.6 inch, with a metal front (IP65) and a depth from 25 mm. The 4.3 to 15.6 inch types have the CPU-T with two Ethernet ports, VNC server and an optional PROFINET IO controller; the 3.5 and 5.7 inch types have the CPU-V or CPU-P with an optional PROFIBUS DP master or slave.

The standard Panel-HMI shows your VisuStage visualization with alarms, trends, recipes and user levels; the CPU-T types add a VNC server for up to four viewers. The EDGE types (TE) also connect the machine to IT: OPC UA server, MQTT publish/subscribe, VPN and Node-RED for data pre-processing. The TEW types add a web server that turns the VisuStage project into a web visualization at the touch of a button.

I/O modules
Operating temperature −20 to +60 °C. The energy module E-Mess UI measures current, voltage, power and energy of a three-phase consumer and fits CPU-V controllers and head stations.

Software
Program the PLC with SIMATIC Manager or TIA Portal; the INSEVIS tools handle everything around it. All four are free downloads and run on a standard laptop.
Engineering
Configuration, visualization and service
ConfigStage configures I/O, interfaces and CPU. VisuStage builds and simulates the visualization and imports S7 variables from SIMATIC Manager and TIA Portal; the full version adds several project languages. RemoteStage shows the visualization on a PC, ServiceStage handles backup, firmware updates and know-how protection.
Existing PLCs
S7-EDGE protocol converter
Reads data from S7 controllers that are already running and makes it available to IT and cloud systems.
FAQ
Your question not listed? Ask us directly.
Can I use TIA Portal?
Yes. INSEVIS S7 controllers are programmed with SIMATIC Manager V5.5 or TIA Portal, in STL, LAD, FBD, SCL or S7-Graph. In the hardware configuration they behave as a CPU 315-2 PN/DP (6ES7 315-2EH14-0AB0, firmware V3.1).
Does my S7-300 program run on it?
INSEVIS CPUs follow the instruction set of the S7-300 CPU 315-2 PN/DP. The CPU-T handles up to 2,048 OBs, FCs, FBs and DBs each and 4,096 bytes of inputs and outputs. Existing function blocks, for example for PID control, can be reused.
PROFINET or PROFIBUS?
The CPU-T types are available with a PROFINET IO controller (order numbers with -PNC) for all PROFINET IO devices. The CPU-V and CPU-P types are available with a PROFIBUS DP V0 master (-DPM) or slave (-DPS), 9.6 kbit/s to 12 Mbit/s.
Do I need runtime licences?
No. The visualization runs without runtime licences or tag limits. ConfigStage, VisuStage, RemoteStage and ServiceStage are free downloads; the VisuStage full version (SW-VS-02) is a company licence for projects in several languages.
Can I connect a Panel-HMI to a Siemens PLC?
Yes. The Panel-HMI connects as active partner via Ethernet S7 communication (RFC 1006) to S7 controllers from Siemens and INSEVIS. You only set the partner IP address and TSAP.
What does an EDGE Panel-HMI add?
EDGE types (TE) add an OPC UA server, MQTT publish/subscribe, VPN and Node-RED, so the machine connects to IT and cloud systems. TEW types also generate a web visualization from the existing VisuStage project.
Can I operate the panel remotely?
Yes. Devices with CPU-T have a VNC server for up to four viewers on a tablet, phone or PC. RemoteStage shows the visualization on any PC screen, for example in a control room.
Which temperature range applies?
Most Panel-PLCs, Panel-HMIs, Compact PLCs and I/O modules operate from −20 to +60 °C; the 15.6-inch types from 0 to +50 °C. Panel fronts are IP65.
Can the devices carry our own logo?
Yes. INSEVIS devices are available with your logo and article number from the first unit, on the label at the rear and, for panels, in the firmware.
