Chapter 6 - 040 Processor Module
72 Adept MV Controller User’s Guide, Rev C
6.1 Introduction
All Adept MV controllers require at least one system processor module; the module can
be an 030 or an 040. You can have both 030 and 040 modules installed, up to a maximum
of 4 modules. The 040 is a single-slot 6U VME module that can serve as a main or an
auxiliary system processor for an Adept MV controller. The CPU for this module is a
Motorola 68040 microprocessor running at 25MHz. The module can be ordered with 4 or 8
MB of DRAM (not field upgradeable).
The 040 has two serial I/O connectors on the front of the module: one is an RS-232 port
and the other is an RS-422 port. In an S-Series Adept MV controller, the programmer’s
terminal connects through the RS-232 port on the primary 040 module. (In an A-Series
controller, the monitor and keyboard normally connect to the Adept VGB module.)
The 040 can be used either as the main system processor, or as an auxiliary processor in
Adept MV controller systems; see section 6.7.
6.2 Connections and Indicators
➊
Status LED’s. When lit:
SF indicates the VMEbus
SYSFAIL
signal is being asserted by
the 040 module. This indicates one of the following
conditions:
• the system is being booted from disk, and V
+
has not yet
completed its initialization.
• the system watchdog timer has timed out.
• another module has issued a
SYSFAIL
signal.
STP indicates the 68040 processor has stopped executing
instructions.
A and VME – these vary in intensity during normal
operation of the system.
SCR indicates the module is configured to be the system
controller (main processor). Otherwise, this LED is off.
B and D are always off.
C is normally on (but off is OK).
➋
Abort switch – stops execution of the software running on
this CPU. This button is pressed only during system tests.
➌
Reset switch – sends a VMEbus reset signal is to all modules
on the backplane.
➍
RS-422 connector – for general serial communication.
➎
RS-232/Term connector – terminal connection with an
S-Series controller; can be used for serial communication
with an A-Series model. See page 74 for more information on
this connector when used with an A-Series model.
