RS Componnets has updated its mini-PLC range from Barth Elektronik, with three new mini PLCs, a new parameter programmer and a touchscreen display. The three new mini-PLCs are based on a 32-bit ARM Cortex processor, which offers a significant step change in performance. Programming is via the established miCon-L software, as well as allowing open source C-programming with the KEIL Vision software suite. All PLCs exhibit 10 I/O and a CAN interface that allows communication with external devices.
