1. working memory

You have the option of expanding the RAM using a memory expansion card up to the maximum printed capacity of the respective CPU.
capacity of the respective CPU.

The MCC(Memory Configuration Card):

- Is primarily used to enable additional working memory, whereby the memory capacity is divided as follows:
Code memory (50%) and data memory (50%); example: MCC 1MB = 512kB (code) and 512kB (data)

- However, the MCC can also be used purely as a memory card for programmes and firmware.

Attention: The CPU only has one slot for memory expansion!

2. power supply

The CPUs have an integrated power supply unit that must be supplied with DC 24V. For operation, an external power supply of
DC 24V is required for operation.

*Type4 can only be operated by CPU 314S & 317S. By using the PS 307 - 1FB70 co-power supply unit, the total current on the backplane bus can be increased by 5.5A.

3. analogue signal modules

General notes on expansion modules

Please note the maximum number of expansion modules supported by the CPU. This information can be found in the technical data of the corresponding CPU.

? CPUs that have an internal SPEED bus can be expanded with all available modules (SPEED bus as well as standard bus).
standard bus).

? CPUs with an internal standard bus can only be expanded with modules that are compatible with the standard bus.

The configurator only displays the appropriate expansion modules that are possible.

4. digital signal modules

5. communication processors

The CPU can use several communication processors in the network so that PROFINET and CANopen, for example, can be used simultaneously as fieldbuses for different drive components.

6. front connector

As an option, 20 and 40-pin front connectors with screw connection or spring-cage terminal can be selected. The various front connectors are also available with pre-assembled individual wires in various lengths.

Spring terminals

Here you can connect wires with a cross-section of 0.08 mm² to 2.5 mm². Both flexible strands without ferrules and rigid conductors can be used.

7. profile rails

Profile rail without SPEED backplane bus

The individual modules are mounted directly on a profile rail and connected via the backplane bus connector. Before installation, the backplane bus connector must be attached to the module from behind. The backplane bus connectors are included in the scope of delivery of the peripheral modules.

Profile rail with SPEED backplane bus

A pre-assembled SPEED bus connector strip is required for the use of SPEED bus modules. This is supplied already assembled on a profile rail with 2, 6 or 10 sockets.
