Claim 0:
1. A control system comprising:
a control device configured to execute a control program controlling a control target while managing a plurality of pieces of process data referred to or updated in the control program, the control device including a first memory that stores a first program, and a first processor that accesses the first memory and executes the first program to periodically transmit one or more data sets, each data set including a value of one or more process data of the plurality of pieces of process data;
one or more information processing devices, each including a second memory that stores a second program, and a second processor that accesses the second program and executes the second program to execute one or more applications using the value of the one or more process data included in the one or more data sets transmitted from the control device; and
a monitoring device including a third memory that stores a third program, and a third processor that accesses the third program and executes the third program to:
monitor a communication load,

determine a transmission setting of a data set transmitted by the control device,
acquire process data necessary for each of the one or more applications executed in the one or more information processing devices,
determine a number of the one or more data sets transmitted by the control device and process data to be included in each of the determined number of data sets according to an evaluation criterion regarding the communication load based on the acquired process data necessary for each of the one or more applications,
update the evaluation criterion according to a result of monitoring the communication load, and
determine the number of the one or more data sets transmitted by the control device and the process data to be included in each data set according to the updated evaluation criterion.
