Abstract
A digital indicating controller outputs data provided by performing control computation of input data and has a communication function with an external apparatus. The digital indicating controller includes a sequence computation section which executes a ladder program with at least any of the input data, the data provided by performing control computation, internal and external setup data, internal and external setup parameters, or data from the external apparatus as condition input and outputs the execution result.
Claims6
A digital indicating controller having a communication function with an external apparatus, said digital indicating controller comprising:
- an input processing means for inputting at least one of analog input and digital input as input data;
- a control computation means for performing control computation using the input data and outputting a computation result;
- a sequence computation means for executing a ladder program with at least any of the input data, the computation result, internal and external setup data, internal and external setup parameters, and data from the external apparatus as condition input, and outputting an execution result;
- and
- an output processing means for outputting the computation result from the control computation means and the execution result from the sequence computation means,
- wherein the ladder program is generated by ladder program construction software, the ladder program construction software being built in parameter setting software or tuning software, the parameter setting software and the tuning software being provided in the external apparatus.
