Master copies

Validity
The following program blocks are located in the master copies of the global library:
● CPU300/400
Program blocks for the S7-300/400 CPU
● CPU1500
Program blocks for the S7-1500 CPU
The blocks are largely identical. Unless otherwise stated, the description applies equally to
the blocks of the S7-300/400 and S7-1500.
If individual blocks cannot be used for all SIMATIC product series mentioned or if functions
for the SIMATIC product series differ, this is expressly indicated.

Data point typicals

5.7.1.1

Types and overview of the data point typicals

Types of the data point typicals
Data point typicals process one or more data points of the same information type, e.g. 4
bytes of binary information, 4 analog values or 1 byte commands, etc.
When a data point typical (FB) is called the corresponding instance DB needs to be specified
in which the data will be written or from which the data to be transferred will be read.
Transfer direction of the typicals
A data point typical for a specific type or amount of information always come in two versions:
● A typical for acquiring and sending
● A typical for receiving and outputting
When using data point typicals a distinction is therefore made according to the transfer
direction:
● Sending typicals
Sending typicals process data and send it to the remote partner.
They have the ending "_S" Examples: Bin04B_S, Ana04W_S
● Receiving typicals
Receiving typicals receive the data from their remote partner.
They have the ending "_R" Examples: Bin04B_R, Ana04W_R
