2.1.1 Special Rules for the Dummy Module (DM 370 Dummy)
Switch Setting on
DM 370 Dummy
A dummy module (DM 370 Dummy) is a module that you can insert instead of a
module that will be used later.
Depending on the switch setting, the module may or may not reserve address
space for a module. For example, address space is reserved for a digital
input/output module but not for an interface module.
Meaning Order Number
A Address space can be reserved.
Modules in a modular DP slave ET
200M: reserve 0 bytes of address
space.
6ES7 370-0AA00-0AA0
NA No address space reserved. None
(Module is "not visible"; it is not
configured)
2.1.2 Special Rules for the Digital Simulation Module
(SIM 374 IN/OUT 16)
The SIM 374 IN/OUT 16 digital simulation module can be used to simulate digital
inputs and outputs.
You cannot find this module in the "Hardware Catalog" window. You must place
the module you want to simulate in the configuration table instead of the SIM 374.
