Chapter 7 - System Input/Output Module (SIO)
82 Adept MV Controller User’s Guide, Rev C
7.1 Introduction
The System Input/Output (SIO) module is a required module in all Adept MV controllers.
The 2-slot-wide SIO is a 6U VME slave module that provides the system I/O functions for
the controller. It serves as the system interface to mass storage (hard drive and floppy
drive), E–Stop circuitry, three user RS-232 serial ports, 20 digital
I/O channels, external front-panel control, and a real-time clock/calendar. This module
also controls AC power for the amplifiers when the system includes the AdeptMotion
VME option or an Adept robot. Communication between the system processor(s) and this
board occurs over the VMEbus.
7.2 Connections and Indicators
➊
Status LED’s. When lit:
OK indicates that this module has passed V
+
start-up test.
E-STOP indicates that the E-stop circuit is open.
ACC V indicates that a 3rd-party VME board has accessed
the Adept VME bus improperly.
SCSI indicates the hard drive is active.
1 - 4 are for Adept Service use only.
➋
DIP Switch (8 position) – see Table 7-1 for functions.
➌
Reset switch – resets all the modules on the backplane.
➍
FP/MCP connector – for an external front panel. You must
install the supplied jumper plug if an external front panel is
not used, otherwise the controller will not turn on.
➎
Drive A – 3.5" floppy drive, 1.4 MB maximum capacity.
➏
RS-232 – three global serial ports for general user serial I/O.
➐
I/O 24V 100 mA (Digital I/O connector) – for 20 channels of
DIO; 12 inputs and 8 outputs. Also, the E-Stop circuit wiring
is installed at this connector; see section 7.7.
NOTE:
The Ethernet connector is not currently used.
Ethernet communication is available for systems using
the 040 processor. Contact Adept Customer Service for
information about the AdeptNet Ethernet option.
