subscriber expects data messages with a time stamp. This information is specified in the
parameters specific to destination subscribers.
The system objects
The system objects provide system-relevant information for the CPU user program.
Configuration of the system objects is optional.
● The WatchDog:
The WatchDog indicates to the CPU program whether the communication between CPU
and local TIM is still working; in other words, whether TD7onTIM is still reading from and
writing to the memory areas of the CPU.
● The PartnerStatus:
The PartnerStatus indicates to the CPU program whether communication with its partners
(other ST7 CPUs or ST7cc/sc control centers) is OK or disrupted.
● The OpInputMonitor:
This indicates the status of operating input to the CPU program (with command, setpoint,
and parameter input).
The data objects
The sending and receiving of process data is configured with the aid of standardized data
objects. According to the two transmission directions, these are divided into:
● Data objects for acquiring and sending data,
Their names have the ending
_S
for Send.
● Data objects for receiving and outputting data,
Their names have the ending
_R
for Receive.
In terms of the names, the data objects of TD7onTIM are identical with those of the data
objects of TD7onCPU. In terms of functionality, they are compatible with each other; in other
words, communication between data objects of TD7onTIM and the corresponding data
objects of TD7onCPU is guaranteed.
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.
The 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 message byte.
The data object
Ana04W_S
, for example, has 4 send channels of the type
send analog
value
.
