3.1.6 Assignment of the Signal Addresses to the Signals (Addressing)

An address (signal address) must be assigned to each terminal so that the processor

can assign the I/O signals of the signal memory to the terminals of the I/O modules.

For analogue I/O modules this is carried out via the software blocks, with which the

relevant modules are linked into the user program and is documented in these blocks.

The following explanations are therefore only valid for binary I/O modules.

The addressing according to DIN, the symbolic addressing and an addressing specific

to AEG are available as types of addressing independently of the selected method of

programming (cf. Table 20).

3.1.6.1 Addressing According to DIN

A DIN address consists of the following:

Slot reference + port number. The slot reference and port number are separated from

each other by a point.

Example: 4.6

→

slot reference 4, port no. 06

5.28

→

slot reference 5, port no. 28

The following is generally valid:

A slot reference is assigned to each slot. The assignment must be carried out dur-

ing the configuration of the hardware and is described in section 3.1.5.

The port number results by counting the terminals for the I/O signals from the top to

bottom for the modules with front connection (cf. Figure 23, left-hand half).

Figure 24 shows the assignment of the port numbers to the ports for the I/O modules

with rear connection.

Example of a Logic Operation with DIN Addressing

An AND block (Dolog block) should linke the entries of input 1 and input 2 of a

DEP 112 (slot reference 5) to each other and output the result to output 16 of a

DAP 106 (slot reference 6).

AND

I5.1

I5.2

O6.16

END

The letters of “I” for input and “O” for output are parameters of the “AND” block and are

automatically offered when the block is called.
