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