Basic settings for TIMs with TD7onTIM
For each TIM with TD7onTIM, several settings must be made that are always required for
communication, for example specifying the read/write cycle.
Parameters specific to the destination subscribers
Destination subscribers are the communications partners of the local CPU of the S7 station.
Data is exchanged with the partner via the TIM module that has TD7onTIM.
The basic settings for each destination subscriber that apply to the data traffic of all DNP3
TIMs in the project with this subscriber are made here.
MODBUS slaves are not configured as destination subscribers. You will find an overview of
configuring MODBUS communication in the section Configuring MODBUS communication
(Page 224).
System objects
The system objects provide information for the CPU user program relating to communication.
Data objects
The sending and receiving of process data is configured with the aid of standardized data
objects. The data objects are available in a standard library and are inserted from the library
into the TD7onTIM configuration.
An example of a data object is Ana04W_S that organizes the transmission of 4 analog
values.
Each data object contains one or more send or receive channels. The number and type of
send and receive channels per data object cannot be modified.
Send and receive channels
The send and receive channels of the data objects are responsible for the processing of an
individual process value, for example for processing and sending an analog value or
receiving and outputting a command.
The data object Ana04W_S, for example, has 4 send channels of the type send analog
value.
