7.3 Dummy module DM 370; (6ES7370-0AA01-0AA0)

Order number

6ES7 370-0AA01-0AA0

Properties

The dummy module DM 370 reserves a slot for a non-configured module. It can be used as

dummy module for:

● Interface modules (without reservation of address space)

● Non-configured signal modules (with reservation of address space)

● Modules which occupy 2 slots (with reservation of address space)

When replacing the dummy module with another S7-300 module, the mechanical assembly

and address assignment/addressing of the entire configuration remain unchanged.

Configuration in

STEP 7

Configure the DM 370 dummy module in

STEP 7

only if you module for a programmed

signal module. If the module reserves the slot for an interface module, you can discard

module configuration in

STEP 7

Modules which occupy 2 slots

Install two dummy modules for modules which occupy 2 slots. You only reserve the address

space using the dummy module in slot "x", rather than the dummy module in slot "x + 1". For

details of the procedure, see the table below.

The rack can receive up to 8 modules (SM/FM/CP.) When using two dummy modules to

reserve a slot for a module of 80 mm width, you may still install 7 further modules

(SM/FM/CP) because the dummy module only uses the address space for one module.
