10 SmartWire-DT universal module M22-SWD-NOP and M22-SWD-NOP-C
10.1 INTRODUCTION
Universal modules can be installed as placeholders for modules that have
been configured in a system but that have not yet been installed or will only
be installed in a future expansion
• On the SmartWire-DT ribbon cable with universal module M22-SWD-
NOP (front mount) or
• In the M22-I…- surface mounting enclosure on the SmartWire-DT PCB
with universal module M22-SWD-NOPC (base mount).
The goal is to make it possible to configure and program a full system or sys-
tem expansion in the corresponding PLC user program without having to
physically install the required hardware right away so that modules can be
easily added later on.
The user program can detect the presence of a universal module (bit 4 and
bit 7 in the first input byte's input table).
If the universal module is replaced with the configured device in the system
later on, the user program in the PLC and the hardware configuration will not
need to be changed.
The interoperability requirements for these SmartWire-DT modules are
described in ￫ Section 13.6, „SWD module interoperability requirements“,
page 259.
10.1.1 Procedure
▶ In the PLC’s control configuration, program the SmartWire-DT modules
that will be required at a later date in addition to the ones that will be
installed and used immediately.
In the hardware installation, install a universal module in place of this
SmartWire-DT module.
▶ In the user program scan whether the the configured SmartWire-DT sta-
tion or a universal module is fitted.
The program flow must be controlled according to this information.
▶ If a universal module is later replaced with the originally configured
SmartWire-DT module, add this module to the SmartWire-DT network by
pressing the “Config.” button on the gateway.
10.2 Surface mounting
The universal modules can be both front- and base-fixed.
