Flexibility / scalability
Apart from the flexible adaptation possibilities in the basic version – e.g. all inputs can be configured as
current/voltage/digital or speed input using init-functions – the possibility to extend the device using so-called “Expansion boards” is the unique characteristic of the STW control device series:
On three (ESX-3XM) or six (ESX-3XL) slots, expansion boards with nearly unlimited additional functions cover a
wide range of applications for your machine. Currently, there are 14 expansion board versions with different inputs and outputs, additional RS232/RS485/ CAN interfaces or even a programmable Linux system including Ethernet and USB available.
There is also the possibility to develop customerspecific expansion boards quickly and cost-effectively in order to fulfill highly customized requirements, e.g. for technical special solutions or to protect against product piracy.
Safety and diagnosability
A second, independent processor monitors the different system voltages and the program sequence. If required, it switches off all outputs using a second switch-off path or resets the main controller.
Digital and analog feedback for nearly all signal paths allow a comprehensive diagnosis of the system including the inputs and outputs.
In particular for safety-related applications, a safety layer API is available, which makes a separation of safe and non-safety (and non-interfering) application parts possible by means of a memory protection unit. This reduces the effort for re-certification in case of changes to the (non-safety) application software substantially.
The creation and maintenance of a safety-related application is possible comfortably using the safety manual and the diagnosis library.
The application software for the ESX series can be created very efficiently either in the standard language “C” or according to IEC 61131-3 (CODESYS V3); a Matlab package is additionally available. Numerous comfort functions, such as current regulators & ramp functions for outputs or frequency determination for inputs are already integrated in the API. Various
additional libraries, such as for example for CANopen, J1939 or error handling, simplify the system integration.
The clearly structured user manual and an inexpensive tool chain complete the comprehensive package.
