Inserting Input and Output Modules

To make the inputs and/or outputs of the input and output modules connected to the I/O bus available in the project, the hardware must be reproduced in the PLC configuration.

Input and output modules connected to the I/O bus of the CPU occupy the I/O following area:

%IB0 .. %IB999 or %QB0 .. %QB999.

There is no fix assignment between module number and the input/output addresses of the channels.

Right-clicking the “I/O-Bus” element in the configuration tree opens the context menu where you can change the “I/O_Bus” mode. Select “Append Subelement”. The sub menu displays all available input and output modules:

Select the desired module depending on its hardware configuration. Repeat this step for all modules. A maximum of 7 input/output modules (10 modules as of V1.2.0) can be appended to the I/O bus.

The following figure shows an example for a configuration with the maximum number of modules:

If the maximum number of modules (7 modules or 10 modules as of V1.2.0) are appended, the context menu item “Append Subelement” can no longer be selected.

Changing the configuration is possible by deleting modules and inserting or appending new modules.

Note

As of firmware version V1.2.0 and PS501 version V1.2, 10 input/output modules can be appended to the I/O-Bus of PM57x, PM58x and PM59x CPU’s, while 7 input/output modules can be appended to the PM55x and PM56x CPUs.
