Possible syntax within the device object

DEVICE name
...
END_DEVICE

declaration of a device configuration, name must be an →IEC-identifier

TYPE PTK := platform-name;END_TYPE

platform for the device configuration

Best practice is to use the content assist in order to select a platform form the list of the available platforms.

COMMUNICATION
(* optional_begin *) VIA comm_node_1; (* optional_end *)
TARGET comm_node_2;
END_COMMUNICATION

specification for the communication with the target system – the details for the target system are being defined in the named sections COMMNODE ... END_COMMNODE that are following

• In case of a target system with a communication without →Gateway, you only need the statement TARGET incl. the relevant section. See the following example 1.

• In case of a target system with a communication via Gateway, you need the additional statement VIA incl. the relevant section. See the following example 2.

COMMNODE comm_node_x
PARAMS := 'jsonstring';
END_COMMNODE

details for the communication with the target system
Mind the following:

• The specifications within PARAMS is a JSON string and depends on the used target system. Contact the vendor of the PLC or logi.cals, whether the device configuration is possible for the target system and which specifications are required.

• A JSON string within the device object must not be longer than 1,023 characters.
