Programming Executive software, use a Generic I/O card in the Rack
Configurator. If a feature of the module is not supported in your
version of the Programming Executive software or you need more

4.6.1 Shark Configuration
In addition to configuring the Shark Interface module in the rack
configuration, the programmer must also write a special configuration
word to slot 0, register 0 in an application task if the Shark rack does
not contain all digital modules and the rotary drop number switch has
been set to a number between 1 and 7. This configuration word
specifies the type of module that is found in each slot of the Shark
drop as shown in figure 4.2. Set bit 15 of the configuration word
equal to one once bits 1 through 10 have been properly set.
Bit 1 = 0: Remote slot 1 contains an analog module
= 1: Remote slot 1 contains a digital module
Bit 2 = 0: Remote slot 2 contains an analog module
= 1: Remote slot 2 contains a digital module
.

.
Bit 9 = 0: Remote slot 9 contains an analog module
= 1: Remote slot 9 contains a digital module
Bit 10 = 0: Remote slot 10 contains an analog module
= 1: Remote slot 10 contains a digital module
Bit 15 = 1: Configuration word is complete
Figure 4.2 Ć Shark I/O Module Configuration Word
A Shark rack can be configured once after it is powered up or after it
is reconnected to the network. If you want to change the
configuration, you must either issue a StopĆAll command from the
AutoMax/DCS 5000 Processor or disconnect the drop cable, change
the configuration word, and then reĆconnect the drop cable.
4.6.2 Rail I/O Configuration (M/N 57C328)
The Remote I/O network transmits rail data from the master drop to
the slave drop and from the slave drop to the master drop depending
on whether the rail contains output or input modules, respectively.
You can mix input and output modules in a rail. Each rail maps to one
input register and one output register in the Remote I/O master.
When a slave drop is initially polled by the Remote I/O master, it will
transmit the rail configuration to the master. The master will use this
information to control access to that drop's registers in the master's
dual port memory via the Multibus. It will allow Read/Write access for
registers defined as OUTPUT and Read Only access to registers
defined as INPUT. All other registers (those without rails connected)
will have no access allowed.
Whenever you change the rail configuration (i.e., you add or remove
rails), the drop will disconnect from the network, reĆrun the powerĆup
