A Control Block task containing the CML block must not be present

when a tick rate of other than 5.5 msec. is used. If a Control Block

task with the CML block is installed and the tick rate is not 5.5 msec.,

the task installation will fail.

A tick rate below 2.0 msec is not recommended for 6010/6011

Processors due to system overhead. A Control Block task containing

with at most 15 average blocks (an average block has a 70

msec

execution time) can run with a 2.0 msec. tick rate; a task with 30

blocks can run at 3.0 msec.

4.4 Restrictions

This section describes limitations and restrictions on the use of this

module.

4.4.1 Number of Processors in a Rack

A maximum of four Processor modules may be plugged into the

rack. M/N 57C430A, M/N 57C431, and M/N 57C435 can be used in

the same rack.

4.4.2 Rack Slot Restrictions

A Processor module can occupy any slot from 0Ć4 in the 6, 10 or

16Ćslot AutoMax rack. If the rack will contain multiple Processors, slot

0 must contain a Common Memory module and slots 1Ć4 can contain

Processors.

4.4.3 Use with the DCS5000 M/N 57C407 Processor

Module or the 57C430 Processor Module

A M/N 57C430A, M/N 57C431, or M/N 57C435 Processor module

cannot be used in a rack that also contains a M/N 57C407 Processor

module or a 57C430 Processor module.

A rack can contain either 1) DCS5000 Processors only, or 2)

M/N 57C430A, 57C431, and 57C435 Processors only. You can,

however, connect the racks together over a network.

4.4.4 Ethernet Commands

All tasks using Ethernet commands must be run on the leftĆmost

Processor in the rack.
