Parameterisation - Festo CPX-FB33 Operating Instructions Manual

Parameterisation

5. Configure MQTT in the software:
– Broker
A broker is configured via the IP address, the port and a keepalive time. Up to three brokers
can be configured for load balancing. If multiple brokers are configured, a broker is randomly
selected for every connection attempt. If a broker is not to be used, the IP address 0.0.0.0 or
port 0 must be assigned. MQTT communication requires at least one configured broker.
– Template selection
The template selection defines which telegrams are to be sent. The default template selection
has the number 0 and contains the Online, Offline, Asset, Diag, Process, Process_Module and
Will telegrams.
– Section from the process image
– Topic-Prefix
The Topic-Prefix defines a character string that is inserted before the topic of each MQTT
message sent.
– Client Identifier
The Client Identifier consists of up to 23 characters. If the Large Client Identifier option is
enabled, the Client Identifier can be expanded up to 128 characters. The Large Client Identifier
option may only be activated if the broker used supports it.
– Retain-Flag
The Retain-Flag option causes the MQTT server to save the last published message for each
topic. As a result, other clients receive these messages immediately after subscribing to a topic
without having to wait for the next update.
– Use saved configuration
This option ignores all configuration settings and instead uses the configuration stored in the
device.
6. Transfer the automation project to the higher-order controller è 7.1 Setting up PROFINET commu-
nication.
7. Start the web server and check the configuration and status via the MQTT page.
8 Parameterisation
The behaviour of the CPX terminal can be set individually by parameterisation. The following parame-
terisation variants are distinguished:
– System parameterisation, e.g. deactivating error messages
– Module and channel-specific parameterisation, e.g. module monitoring, settings for errors, adjust-
ment of debouncing times for inputs
– Parameterisation of the diagnostic memory
The following parameterisation options are available:
– Parameterisation of the CPX terminal with PROFINET engineering software
– Parameterisation with the operator unit
– Parameterisation via the Festo Maintenance Tool
