Allen Bradley ETH
Description
The adapter allows to connect devices supporting Allen Bradley ETH.
Configuration
The following configuration options are available when creating an adapter:
PLC Address
This field requires the PLC address in form of the IP without the prefixed protocol (e.g., 192.168.34.56).
Polling Interval
The polling interval requires a number in milliseconds, which represents the interval in which the adapter will poll the PLC for new data. For instance, a polling interval of 1000 milliseconds will configure the adapter to send a request to the PLC every second.
Supported Transports
The following transports are supported by this adapter:
- tcp
Transport Metadata
Required
tcp
Advanced
tcp
- keep-alive: Should keep-alive packets be sent? (BOOLEAN)
- no-delay: Should packets be sent instantly or should we give the OS some time to aggregate data. (BOOLEAN)
- default-timeout: Timeout after which a connection will be treated as disconnected. (INT)
Protocol Metadata
Required
Optional
- station: Id of the station we want to connect to (INT)
Tags
The syntax to define tags is based on the PLC4X syntax, see https://plc4x.apache.org/users/protocols/s7.html. Address Pattern:
propertyName=%{Memory-Area}{start-address}:{Data-Type}[{array-size}]
temperature=%I0.0:INT
Best Practices
Instead of creating a large event containing all nodes that should be available in StreamPipes, consider to group the fields logically into smaller adapters. This will ease the definition of pipelines for users and eases future modifications.
