Installing 575 System Hardware SIMATIC 545/555/575 System Manual

Installing VMEbus Boards (continued)

The following guidelines apply when installing the 575 CPU into the

VMEbus base.

• If you are using a 575–2105/–2106, ensure that you have correctly

configured the dipswitch on the CPU board before installing the board

into the VMEbus base. Refer to Section 4.10 for the configuration

settings.

• If you are using a 575–2104 CPU, ensure that you have correctly

configured the dipswitches on any Series 505 remote I/O or

PROFIBUS-DP I/O annex cards (if installed). Refer to Section 4.10 for

information on how to configure the annex card dipswitch.

• The board that you install in slot 1 (leftmost VMEbus slot) must

perform as the VMEbus system controller. If this board is a 575 with

the

USER-CONFIGURED option set, you must also set the PRIMARY 575

dipswitch (SW7). A third-party master can be system controller.

• When the 575 configures applications at powerup, the primary 575 is

assigned as application A. Secondary 575s are assigned to application

B, C, etc., starting with the leftmost secondary 575 and proceeding to

the right-most secondary 575. To avoid confusion when viewing the

system configuration with TISOFT, install the primary 575 as the

left-most 575 in the chassis.

• If you leave an open slot between boards, set the dipswitches in the

backplane to the appropriate values. See “Setting the Daisy-Chain

Switches” on page 4-41.

• You can place third-party VMEbus boards between 575 CPUs, but be

sure to install any boards that do not pass daisy-chain signals to the

right side of boards that require them.
