Interface Modules
Operation at Preset <> Actual Configuration
If the parameter is enabled and:
• Modules are removed and inserted during operation, this does not lead to a
station failure of the ET 200S.
• The actual configuration differs from the expected configuration, the ET 200S
remains engaged in data transfer with the DP master.
If the parameter is disabled and:
• Modules are removed and inserted during operation, this leads to a station
failure of the ET 200S.
• The actual configuration differs from the expected configuration, there is no
data transfer between the DP master and the ET 200S. Exception: Option
handling with RESERVE modules (see Section 3.8).
Option handling, general
Using this parameter you can enable or disable the option handling parameter for
the entire ET 200S.
Option handling: slots 2 to 63
Using this parameter you can enable or disable the checking of the configuration.
• Slots 2 to 63 are enabled: Instead of the configured electronic module you can
also insert a RESERVE module in the relevant slot without a diagnosis being
reported.
• Slots 2 to 63 are disabled: Only the configured module can be located on the
relevant slot. RESERVE modules are treated as incorrect modules. Depending
on the setting of the "Operation at Preset <> Actual Configuration" parameter,
the ET 200S will either fail or remain in data transfer.
Diagnostic interrupt
This parameter allows you to enable or disable diagnostic interrupts. Diagnostic
interrupts are only supported when the ET 200S is in DPV1 mode.
Hardware interrupt
This parameter allows you to enable or disable hardware interrupts. Hardware
interrupts are only supported when the ET 200S is in DPV1 mode.
Insert/remove-module interrupt
This parameter allows you to enable or disable insert/remove-module interrupts.
Insert/remove-module interrupts are only supported when the ET 200S is in DPV1
mode.
