CTI 100.DIO8.WLAN.W Starterkit

Controlling and monitoring installations, systems and processes in the field, logging application data or energy consumption values, and displaying data or operating states are requirements in our world that we can no longer do without. Wherever global availability, mobility and communication with distributed systems are required, facilities for telecontrol/teleservice must be implemented. The simple provision of a modem or an Ethernet interface as a means of communication is not enough to cover the requirements for affordable global availability. The level at which the functions provided are to be accessed and used is a critical factor for problem-free telecontrol/teleservice. For this purpose, the com.tom product range offers the appropriate web portal, com-tom CloudServer, for providing data, as well as a host of different devices.

The com.tom product range offers different devices for implementing a wide range of interfaces to the plants, systems and processes.
Communication from the field to the com.tom CloudServer is a fixed element of any com.tom product.

com.tom BASIC uses the Ethernet interfaces provided with all com.tom devices to offer the com.tom PORTAL solution for environments with a WAN connection in place.

The pre-installed IPC@CHIP® RTOS real-time operating system enables the easy creation of application-specific programs.

WEB-PLC is a WEB-based graphical editor solution for basic PLC control functions.
Operations such as AND, OR, XOR, FF, TIMER, COUNTER, COMPARE and more are provided for implementing simple PLC functions.
Additional protocols (eg Modbus) are available in the WEB-PLC. The communication to the com.tom PORTAL is always available and only the appropriate configuration is required.
Other service and remote services are also provided, such as OpenVPN, NAT and COM server.

The CODESYS market leader enables unrestricted programming in IEC 61131-3 for the user. Additional protocols (eg Modbus) are available in CODESYS.
The communication with the com.tom PORTAL is always available and also here only requires the appropriate configuration.
Other service and remote services are also provided, such as OpenVPN and NAT.

On the process side, communication is implemented via a serial interface or via digital inputs/outputs.

The local digital inputs/outputs can also be assigned to simple PLC functions. Furthermore, these functions do not require the use of an IEC programming interface.
