Summary: The procedure in principle
The following phases are distinguished when it comes to the implementation of a standard
machine concept:
1.
Engineering phase: Creating a standard machine project and loading into specific machine
or plant:
– Completely configuring all IO devices (options) ever required in a specific machine or
plant
– Configuring as optional those IO devices that will be omitted in specific machines or
plants
– Preparing user program (see Configuring flexible order of IO devices (Page 1)) with the
possibility of selecting on-site the actually existing configuration via switch or
HMI device
2. Commissioning phase: Preparing specific machine or plant for operation:
– Integrating machine or plant in the on-site network (see Adapt multiple use IO systems
locally (Page 1))
– Selecting the currently existing configuration of the IO system via configured option
5.10.2.2 Configuring IO devices as optional
Requirements
• IO controller supports configuration control for IO systems, for example CPU 1516-3 PN/DP
as of firmware version 1.7
• STEP 7 V13 SP1 or higher
• The rules (Page 1) for the establishment and operation of a standard machine project have
been considered.
Port interconnection
As of STEP 7 V15.1, port interconnection is not necessary for optional IO devices.
A port interconnection between the devices of the IO system that you want to customize with
the user program is mandatory in the following cases.
•
You have configured IRT.
• You have configured MRP.
• You are using STEP 7 <= V15.
