Abstract: Various embodiments of the teachings herein include methods for implementing communication conversion between a server-client system and a publish-subscribe (pub-sub) system. An example may include: receiving a message from the pub-sub system, wherein a topic of the message includes information related to a target service in the server-client system to which the message is to be sent, and a payload of the message includes identification information of a consumer in the pub-sub system, wherein the consumer is to receive a response message from the server-client system; parsing the message to determine a host and a service provider that provide the target service, and the consumer who is to receive the response message; sending a request message for the target service to the service provider on the determined host; receiving the response message; adding the identification information to the response message; and sending it to the pub-sub system.

Abstract: A method, apparatus and system are for displaying measurement information. An embodiment of the method includes: obtaining a display instruction for displaying measurement information of at least one second transmitter; and displaying, after obtaining the display instruction, the measurement information of the at least one second transmitter on a display screen of the a first transmitter. The first transmitter and the at least one second transmitter perform data communication with a distributed I/O device according to a preconfigured data transmission path. Further, the measurement information of the at least one second transmitter is obtained by means of the distributed I/O device according to the preconfigured data transmission path. The embodiment of the method enables an operator to conveniently view the measurement information of the second transmitter on the first transmitter nearby, without viewing the information on a remote device manager or the second transmitter.
