Product Selection and Project Engineering
The following conditions must be observed during project engineering:
• Installation of the device is permissible only if it is used in accordance with its intended use;
see chapter 3.1.
• For permissible mounting positions for operation of the device, see chapter 6.
• No separate auxiliary power is required.
• The maximum number of I/O modules on the BusRail is reduced by the number of
redundant I/O module pairs.
• The system requirements and behaviour with I/O module redundancy are described in the
corresponding IS1+ coupling description.
5.1
Product Selection
The selection of the suitable termination board and connecting cable depends on the
following conditions:
• Type and redundancy capability of the I/O module
• Current firmware supports the redundancy of the I/O module
