Method and system for safety monitored terminal block

A control device comprising:

• an input section configured to receive input signals from a controlled process;
• a controller connected communicatively coupled to the input section and configured to receive the input signal and in response generate a control signal using the input signals;
• an input output termination device coupled to the input section and the controller, the input output termination device having a safety device, the safety device comprising:
• at least one safety logic block;
• a terminal block having at least two communication paths;
• a safety output section communicatively coupled to the at least one safety logic block, the safety output section configured to transmit a safety output signal to the controlled process;
• and
• a control output section communicatively coupled to the controller, the control output section configured to transmit control signals from the controller to the controlled process;
• wherein the input signal from the controller process is bifurcated in the terminal block to a first path signal and a second path signal;
• wherein the at least one safety logic block receives the first path signal and in response generates a safety output signal, and wherein the second path signal is received by the controller in parallel with the first path signal, the second path signal bypassing the safety device;
• wherein the at least one safety logic block is configured to transmit a safety output signal to the controlled process independent of the control signals that are transmitted from the controller to the controlled processes;
• wherein the at least one safety logic block comprises precompiled safety certifiable logic;
• and
• wherein the at least one safety logic block comprises a plurality of safety logic blocks, wherein an output of a first of the plurality of safety logic blocks is coupled to an input of a second of the plurality of safety logic blocks.
