Rated for SIL 3 and conforming to IEC 61508 and EN ISO 13849-1 PL e, the terminals utilize the performance of EtherCAT--the EL6900 safety PLC terminal can integrate up to 128 4-channel safety terminals (512 safety devices) and is capable of processing 256 safety-relevant function blocks. The safety function blocks integrated into the EL6900 Safety PLC are configured according to each unique application. Safety functions can be easily programmed such as emergency stop, safety door monitoring, two-hand control, serial/parallel muting, timers and latches. Even a connection shutdown function can be established so interchangeable sections of equipment with safety terminals installed can be removed from the machine without causing safety system errors.
