On March 2013, Rohtek Automation unveiled its Programmable Logic Controller Professional Training Box. The Rohtek Training Box is an excellent tool for learning ladder logic programming in realistic applications. The ladder logic language is very similar among different brands of PLCs and the software development environment, called WinProLadder, is very similar to AB's RSLogix. Programming skills developed with the Training Box are applicable to PLC programming in general. It contains the basic items required by PLC’s digital I/O training, such as the FBs-24MCT highly functional main unit, the FBs-CM25E Ethernet module, digital input socket, simulated switches, and digital output socket. Also included are advanced application peripherals like encoder and stepping motor (coupled with belt for transmission), seven segment display, 10 LED indicators, thumb wheel switches, and keyboard. The built-in RS232, RS485 and the Ethernet three ports (can be expanded to five with communication boards) capable of connecting with other slave training boxes to conduct networking on-line and easily teach loading, monitoring, modifying, and storing computer connections and advanced intelligent ASCII peripherals.
