Installation and Startup
This section describes how to prepare digital input/output modules for
installation, and how to install and wire them.
8.2.1
Setting the Module Address
You set the module address on the addressing switch. This also
establishes the necessary assignments between user program and
process connection.
The address of the digital input modules (input bytes IB 0 to 255 or
252 for the DI/DQ 482) and digital output modules (output bytes
QB 0 to 255 or 252 for the DI/DQ 482) is the sum of the binary
significances established by depressing the individual rockers in the
On setting (
•
).
The modules are addressed by the STEP 5 program under their
parameters (byte address).
Labelling field
You can affix the adhesive label with the desired module address on a
labelling field under the addressing switch. Suitable labels are
supplied with the CC.
The switch rockers with which the module address (IB n or QB n) is
specified as a decimal number, are marked by dots on the label.
Do not use a pencil to set the addressing switch.
