Interrupts for Modules with Packed Addresses
Configuring the Distributed I/O (DP)
If the submodule can trigger interrupts and its addresses are packed (that is, it has
a bit address not equal to 0), then you must use the ET 200S address dialog to
assign a dialog address.
The diagnostic address is essential to assigning a DPV1 interrupt to the submodule
as the interrupt trigger. Only when a submodule has this "unpacked address" can
the CPU assign an interrupt and store information about the interrupt in the start
information for the interrupt OB or in the diagnostic buffer. The CPU cannot use a
"packed" address to do this.
This diagnostic address assigned to the submodule is only valid for interrupt
processing (interrupt OB). For processing input and output data in the user
program, the submodule still has the packed addresses.
Note
If the submodule addresses are packed, then the insert/remove interrupt for the
ET 200S is also disabled!
3.6.5 ET 200iS
Configuration
You can either configure ET 200iS and its electronic modules in the HW Config or
conveniently do so with the SIMATIC PDM option package The respective system
requirements and procedure are described below:
System Requirement
STEP 7 as of version 5.1, SP 2, Hotfix 1 or PCS7 as of version 5.2.
In this case, ET 200iS is in the STEP 7 hardware catalog. Diagnostic interrupts,
process interrupts, inserting and removing interrupts and time stamps are
supported.
Configuring the ET 200iS
1. Start the SIMATIC Manager.
2. Configure ET 200iS with HW Config.
- Create new project.
- Drag and drop the module from the hardware catalog to the configuration
table.
3. Configure the time stamping (optional).
4. Save or download the configuration to the DP master.
