SIMATIC 545/555/575 System Manual

Installing 575 System Hardware

Follow the guidelines and steps below when installing a 575 as system

controller and/or as primary.

NOTE: Read and abide by the warnings and cautions at the beginning of

this section.

1. Ensure that all power is disconnected from the VMEbus base.

2. If the 575 CPU is to perform as the VMEbus system controller, install it

in slot 1.

If the 575 is not performing as the VMEbus system controller, then

install the 575 primary as the leftmost 575 CPU in the system,

according to the “General Guidelines” at the beginning of this section.

3. Install 575 secondary CPUs, if any. (Follow the procedure on page

4-36.)

4. Power up the 575 system.

5. Reconnect the battery after the PCG LED lights up on the 575 system

controller; that is, when the LED on the bottom right-hand side turns

on. See Figure 4-19 for the location of the LEDs.

6. Load your program(s).
