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

4.12 Installing VMEbus Boards

The guidelines in this section apply when you install boards into the local

VMEbus base.

CAUTION

Never attempt to install Series 505 I/O in a VMEbus base.

Doing so results in damage to equipment.

Series 505 I/O is only available as an option for the remote bases in your 575

system.

NOTE: You must adhere to VME addressing requirements for all the

products that you install in the system. Refer to the IEEE 1014 VMEbus

Specification and the literature accompanying other vendors’ products for

additional details required for installation.

WARNING

Installing or removing a board from a powered-up base disrupts your process.

Disruption of your process can cause death or serious injury to personnel,

and/or damage to equipment.

Ensure that all power is disabled before installing or removing boards from

your VMEbus base.

CAUTION

Disconnect the battery (in addition to disabling power) before installing or

removing a third-party board if that board makes a connection to the battery

backup (+5 V STDBY) circuit of the VMEbus backplane.

Failure to follow this caution could result in damage to the 575 power supply.

Do not install or remove a third-party board with connection to a +5 V STDBY

unless the battery is first disconnected. Section 4.8 describes how to disable

the battery.
