The invention claimed is: 1. A control system comprising: a control unit configured to control a target controlled apparatus; and a communication processing unit disposed on a communication path between the target controlled apparatus and the control unit and configured to execute communication processing in communication between the target controlled apparatus and the control unit, wherein the target controlled apparatus and the control unit are configured to communicate with each other via the communication processing unit, wherein the communication processing unit sequentially measures a processing time of the communication processing and sequentially outputs delay information indicating the measured processing time to the control unit, and the control unit sequentially acquires the delay information from the communication processing unit, and based on the acquired delay information, sequentially updates delay information incorporated in a control algorithm for controlling the target controlled apparatus, wherein each of the control unit and the communication processing unit is implemented by: i) computer executable instructions executed by at least one processor, ii) at least one circuitry or iii) a combination of computer executable instructions executed by at least one processor and at least one circuitry. 2. The control system according to claim 1 , wherein the communication processing unit measures the processing time based on a start time of the communication processing and an end time of the communication processing. 3. The control system according to claim 1 , wherein, when a time obtained by subtracting the processing time measured last time from the processing time measured this time is longer than a predetermined length, the control unit updates the delay information incorporated in the control algorithm. 4. A control method performed by a control system including a control unit configured to control a target controlled apparatus, and a communication processing unit disposed on a communication path between the target controlled apparatus and the control unit and configured to execute communication processing in communication between the target controlled apparatus and the control unit, wherein the target controlled apparatus and the control unit are configured to communicate with each other via the communication processing unit, wherein each of the control unit and the communication processing unit is implemented by: i) computer executable instructions executed by at least one processor, ii) at least one circuitry or iii) a combination of computer executable instructions executed by at least one processor and at least one circuitry, the control method comprising: sequentially measuring, by the communication processing unit, a processing time of the communication processing and sequentially outputting delay information indicating the measured processing time to the control unit, and sequentially acquiring the delay information from the communication processing unit, and based on the acquired delay information, sequentially updating delay information incorporated in a control algorithm for controlling the target controlled apparatus. 5. A control system comprising: a control unit configured to control a target controlled apparatus; and a communication processing unit disposed on a communication path between the target controlled apparatus and the control unit and configured to execute communication processing in communication between the target controlled apparatus and the control unit, wherein the communication processing unit sequentially measures a processing time of the communication processing and sequentially outputs delay information indicating the measured processing time to the control unit, and the control unit sequentially acquires the delay information from the communication processing unit, and based on the acquired delay information, sequentially updates delay information incorporated in a control algorithm for controlling the target controlled apparatus, wherein, when a time obtained by subtracting the processing time measured last time from the processing time measured this time is longer than a predetermined length, the control unit updates the delay information incorporated in the control algorithm, wherein each of the control unit and the communication processing unit is implemented by: i) computer executable instructions executed by at least one processor, ii) at least one circuitry or iii) a combination of computer executable instructions executed by at least one processor and at least one circuitry. 6. A control method performed by a control system including a control unit configured to control a target controlled apparatus, and a communication processing unit disposed on a communication path between the target controlled apparatus and the control unit and configured to execute communication processing in communication between the target controlled apparatus and the control unit, wherein each of the control unit and the communication processing unit is implemented by: i) computer executable instructions executed by at least one processor, ii) at least one circuitry or iii) a combination of computer executable instructions executed by at least one processor and at least one circuitry, the control method comprising: sequentially measuring, by the communication processing unit, a processing time of the communication processing and sequentially outputting delay information indicating the measured processing time to the control unit, sequentially acquiring the delay information from the communication processing unit, and based on the acquired delay information, sequentially updating delay information incorporated in a control algorithm for controlling the target controlled apparatus, and updating the delay information incorporated in the control algorithm when a time obtained by subtracting the processing time measured last time from the processing time measured this time is longer than a predetermined length.
