1394 System Overview
GMC System
The 1394 GMC System provides all the functionality of the IMC S
Class Compact Motion Controller and power conversion within the
1394 system module. Allen-Bradley offers two versions of the 1394
GMC system module (Standard GMC and GMC Turbo). Both
systems are completely programmed and commissioned using
GML (Graphical Motion Control Language), offer Allen-Bradley
DH485, RS-232, and RS-422 as standard communications, and have
Remote I/O and AxisLink available as communication options.
The 1394x-SJTxx-C (Standard GMC) system supports four axis
modules and provides four channels of auxiliary encoder input. The
1394C-SJTxx-L (Standard GMC) provides the same functionality of
the 1394x-SJTxx-C, but supports only one axis module and provides
two channels of auxiliary encoder input.
In addition, the 1394x-SJTxx-T (GMC Turbo) provides more GML
application program memory and executes the programs faster. The
1394x-SJTxx-T offers 64K of memory with a 32-bit processor while
the 1394x-SJTxx-C offers 32K of program memory with a 16-bit
processor. The 1394x-SJTxx-T also includes a direct, high speed link
to the SLC 5/03, 5/04, or 5/05 that simplifies the programming
required to transfer data between the 1394x-SJTxx-T and the SLC.
