FC 44 - TCS Digital Output (COM and CLC Modules)

The TCS digital output function code sends a digital signal from a controller module fixed output block to a controller module termination device. The block number referenced must be a digital output block (231-234).

 

To insure that the signal successfully transfers, the digital signal generates a point quality flag. To test the quality of the signal, include a function code 31 (test quality) block in the configuration. The quality of the point cannot be used as an input to any other type of block. The digital output value can be used as an input to any digital processing block.
