Communication systems

General

Information needs to be transmitted between the SYS 500 system server and process
units. In some cases information from the process units needs to be transmitted to
the network control centers as well. Commands sent from the network control
centers to process units need to be transmitted in the same way. The data
transmission is a task for the communication system. The process unit protocol is
often different from the network control center protocol. This is why a protocol
conversion is needed.
The communication system also handles the communication between other devices
in the MicroSCADA system, for example, between two system servers or two
communication servers.
The communication can be divided into upper level communication and process
communication. See Figure 4.1.-2. Some protocols used for communication are
shown in the picture.
