Small PLCs offer a low-cost start for simple control tasks. INSYS supports the two most common small PLC systems SIEMENS LOGO!™ and Moeller easy™ with extended versions of the GSM adapter INSYS GSM.
The status of a SIEMENS LOGO!™ system (inputs, outputs, markers) may be completely controlled by INSYS GSM Logo - in case of changes or overflows autonomous alarm messages are sent by SMS. In addition, a memory image (PA buffer) and the actual values of function blocks may be retrieved via SMS!
