●
– For the assignment of the PLC tabs, see section Data point configuration (Page 104).
– For the data point type, see Datapoint types (Page 111).
●
See following sections
– For the type of transmission, see section Process image, type of transmission, event
classes (Page 113).
– For the read cycle see section Read cycle (Page 115).
– High priority
If the option is enabled, the transfer has higher priority (important process data). The
values of the data point are transferred before those of lower priority data points.
In dial-up networks the high priority leads to connection establishment only when the
value of the data point is transferred with the transfer mode “Spontaneous (direct
transfer)“ (see “Trigger” tab).
●
– Object number
The object number of the data point must be unique. The maximum permitted number
of data points per SINAUT object must not be exceeded.
Refer to the column “Number of data points per SINAUT object” in the section
Datapoint types (Page 111).
– Object channel
Channel number of the SINAUT object
– Partner object number
Object number of the data point on the partner.
Per object number, you need to specify a unique object number of the
communications partner. This results in unique pairs of "Object number" and "Partner
object number".
See also section Partner stations (Page 127).
During the configuration of the user data to be transferred by the module, each data point is
assigned a protocol-specific data point type. The data point types supported by the module
along with the compatible S7 data types are listed below. They are grouped according to
format (memory requirements).
