A connection provides connectivity to some other things over some protocol (see also Industry Protocol Details) and implements connect and disconnect functionality.

type: enum
The value of this property must be equal to one of the following values:

is optional
type: enum
, must be one of connected
, disconnected
default: connected
Only set this property if your protocol-mapper runs as in a distributed mode, i.e. on an agent instance separated from the Connectware. If this is the case, specify the corresponding agent name here.

type: string
default: protocol-mapper

Most protocols expose a property connectionStrategy
which allows configuring the incremental delays between re-connection attempts. Each protocol provides defaults for this configuration which is documented on each of them. In general an initialDelay
property determines how many milliseconds to wait before the first attempt to re-connect is executed and then this value is multiplied by the configured incrementFactor
, replacing the original initialDelay
, up to a maximum configured maxDelay
that once reached causes all subsequent re-connection attempts to occur after that many milliseconds. Once the connection is restablished the initialDelay
is reset to its original value. The procotols Mqtt, Opcua, S7 and Sinumerik use their own strategy described in each of them.
