Double-Width Terminal Block; Additional Parameters On The "Redundancy" Tab For Redundant Modules - Siemens SIMATIC ET 200SP HA Equipment Manual

Parameters/address space
5.2 Description of parameters
A potential group begins with a light terminal block, via which the required supply voltage is fed
to all I/O modules of the potential group. The light terminal block interrupts the self-assembling
voltage buses to the left neighbor.
All other I/O modules of this potential group are plugged into dark terminal blocks. I/O modules
on dark terminal blocks take the potentials of self-assembling voltage rails from the left
neighbor.
A potential group ends with the dark terminal block, which follows a light terminal block or a
server module in the station configuration.
Further information on the configuration of the potential group can be found in system manual
"Distributed I/O System ET 200SP HA
109761547)".
5.2.7

Double-width terminal block

Definition
Specifies that a double-width terminal block is used at this slot.
This parameter is only active if the module is plugged into an even-numbered slot.
If set to "Yes", no additional module can be configured in the slot to the right of the current slot.
When using the terminal blocks with potential distributors, you have to activate the parameter
"Double-width terminal block".
This parameter only affects the configuration in HW Config.
5.2.8

Additional parameters on the "Redundancy" tab for redundant modules

Introduction
For redundant digital input modules, define additional parameters in the "Additional
parameters" section of the "Redundancy" tab.
Discrepancy time (ms)
The parameter is displayed if redundancy is configured.
The discrepancy time is the maximum permissible time in which the redundant input signals
may differ.
• If the discrepancy time = "0" is configured, the discrepancy analysis is disabled.
• If a discrepancy time not equal to "0" is configured, a discrepancy analysis is performed.
