Installing 575 System Hardware SIMATIC 545/555/575 System Manual
Configuring the CPU (continued)
When SW6 is set to the On position, the CPU is in the AUTO-CONFIGURED
mode.
In the
AUTO-CONFIGURED mode, the 575 Release 5.0 is compatible with
575 Releases 2.0 through 3.1.
In AUTO-CONFIGURED mode, a 575 CPU must be located in slot 1.
During FAULT recovery, the 575 CPU in slot 1 issues SYSRESET*.
NOTE: If any 5752104 CPU in your system does not have a remote I/O
annex card, then the entire system must operate in the
AUTO-CONFIGURED
mode. Verify that the 5752104 CPUs in your system that do have an annex
card have SW6 set to the On position; you do not need to do anything to the
rest of the switches.
To select the USER-CONFIGURED mode, you must ensure that SW6 is in the
Off position for every dipswitch, and that SW3 through SW6 are set to the
same positions for every 575 in the system. (5752104 CPUs require an I/O
annex card in order to select user-configured mode.)
In the
USER-CONFIGURED mode, the position of switch SW7 determines
whether the CPU is a primary or secondary 575. Setting SW7 to the On
position indicates that the CPU is the primary 575 in the system; setting
SW7 to the Off position indicates that the CPU is a secondary 575.
Only one 575 can be the primary 575 in a system. If a 575 CPU resides in
slot 1 (the system-controller slot), then it is automatically configured as the
primary 575 CPU, regardless of the position of SW7. Do not configure any
other 575 as your primary.
Switch 8 is used to allow the CPU to perform an Auto Recompile during
runtime. Switch 8 is shipped in the disabled (left) position. To activate this
feature, set the switch to the right (enabled) position. Refer to Appendix F
for more information about the Auto Recompile function.
