Abstract
An industrial control system is provided that includes a first control set, having a first frame period. The first control set includes at least one first input/output (I/O) pack; and at least one first controller. The industrial control system also has a second control set with a second frame period. The second control set includes at least one second input/output (I/O) pack; and at least one second controller. A mixed-frame rate logic device is also included with the industrial control system. This device may handle sharing of input data, output data, or both provided by the first control set to the second control set when the first and second frame periods are different.
Claims20
An industrial control system, comprising:
- a first control set configured with a first frame period, wherein the first control set comprises:
- at least one first input/output (I/O) pack;
- and
- at least one first controller;
- a second control set configured with a second frame period, wherein the second control set comprises:
- at least one second input/output (I/O) pack;
- and
- at least one second controller;
- and
- a mixed-frame rate logic device configured to handle sharing of input data, output data, or both provided by the first control set to the second control set when the first and second frame periods are different.
A tangible, non-transitory, machine-readable medium, comprising machine-readable instructions to:
- transmit input data, output data, or both from a first control set configured with a first frame period;
- receive the input data, the output data, or both at a second control set configured with a second frame period, wherein the first and second frame periods are different;
- modify a timeout threshold to account for the different first and second frame periods;
- and
- modify processing of the input data, the output data, or both by the second control set to account for the different first and second frame periods.
A method, comprising:
- transmitting input data, output data, or both from a first control set configured with a first frame period;
- receiving the input data, the output data, or both at a second control set configured with a second frame period, wherein the first and second frame periods are different;
- modifying a timeout threshold to account for the different first and second frame periods;
- and
- modifying processing of the input data, the output data, or both by the second control set to account for the different first and second frame periods.
