IB-11B012 INDUSTRIAL INDEXING SYSTEMS, INC.
USER'S GUIDE MOTION CONTROL SYSTEM, MSC-250
3 - 2 OPERATION AUGUST 1998
Each I/O module location has a specific address. Each location can be used as either an
input or an output location. In addition, the locations in any one group of 16 I/O module
locations can be used for programmable limit switches.
PORT 1 is used for communication with the MSC Tool Kit. However, PORT 2 and PORT 3
are addressable by the program for communication with other devices during control
operations.
The PROM POCKET location can hold a PROM with the program which is to be used by
the controller. The program can also be written so data is stored to a PROM in the PROM
POCKET, or so data is retrieved from the PROM, or both. Although data can only be
written to the PROM once, it can be retrieved from the PROM as often as necessary.
NOTE
For additional information on creating the system control
Macroprogram, refer to the Macroprogram Development System
Instruction Book, the IOE-850 I/O Expander Instruction Manual and
the instruction manuals for any other accessories being used in the
system.
3.1.2 LOAD MACROPROGRAM TO MEMORY
The MSC-250 has 32,000 bytes of non-volatile memory for storage of the control program.
This memory location is protected by a lithium battery to maintain the information when the
power is turned off to the controller. Once a control program is loaded into memory, the
MSC-250 will continue to use the program until a new program is loaded.
The program can be loaded into memory directly from a personal computer communicating
through PORT 1. It can also be loaded from a PROM placed in the PROM POCKET.
NOTE
The PROM can be "burned in" using the PROM POCKET in the
MSC-250 controller and direct communication from the MSC tool kit.
This prom can then be used to load the program to other controllers.
Refer to the Macroprogram Development System Instruction Book
for instructions on preparing and using the PROMs.
