Claim:
1. A process control system for controlling an industrial process, comprising: a first field device configured to generate a first field device state information in a first code system, the first field device state information indicating at least one of an abnormality and a malfunction of the first field device; a second field device configured to generate a second field device state information in a second code system, the second field device state information indicating at least one of an abnormality and a malfunction of the second field device, the second code system being different from the first code system; a plurality of network devices connected with the network and including at least a first network device and a second network device, the first network device being configured to receive the first field device state information in the first code system and convert the first field device state information in the first code system into a first field device state information in a uniform code system, and the second network device being configured to receive the second field device state information in the second code system and convert the second field device state information in the second code system into a second field device state information in the uniform code system; a controller connected with a network and communicating with the plurality of network devices, the controller being configured to receive the first field device state information in the uniform code system from the first network device and the second field device state information in the uniform code system from the second network device; and a higher-level managing apparatus connected higher in level of the network than the controller and configured to receive, from the controller, the first field device state information in the uniform code system and the second field device state information in the uniform code system, the higher-level managing apparatus configured to decipher, using a uniform dictionary for the uniform code system, the first field device state information in the uniform code system and the second field device state information in the uniform code system.
